Something a little different:
http://tlatet.blogspot.co.uk/2008/03/eddingtonnumber.html or http://en.wikipedia.org/wiki/Arthur_Stanley_Eddington#Eddington_number_.28cycling.29
If you are on MCL, go to the "view" page, that gives you a complete list of all your rides that you can export to CSV. Then it's easy to sort in Excel.
I'm on "49", so when my legs have recovered from the 400km at the weekend it's inspiration time to go for another ride of at least 80.463 km

41. And rising. ;D

105km  rising slowly (sounds like the shipping forecast)

80 miles or 128Km, and unlikely to increase anytime soon.

We did this a while ago. I had a spreadsheet once into which I poured all my bikejournal / cyclogs / mycyclinglog data, but I haven't kept it up to date. From memory, mine was 42 but I would think that it has risen a little.

62 miles.

I've just checked Mycyclinglog and since 1/1/2010, when I started recording rides there, it is 55 (miles).

81 (miles) or 104 (kilometres).

I believe the Eddington Number has to be in miles.
Unfortunately, it doesn't include the hundreds of long rides I undertook as a young man, though I doubt that the number would be higher than sixty even so.

126 miles
It's probably not coincidence that this is very close to Randonnee distance :).

Wasn't there a different name for the number in km? I'm pretty certain that someone did cite it in a previous thread on the topic.

I've just gone through Bikejournal from 2007 to 2009. I exceeded 55 miles on 78 occasions during those three years.
I suspect that, from my previous cycling life, I would have to add only one ride to my Eddington list to have any effect at all, and that was the Essex CT 100mile ride in 1981. I don't remember any other ride over 70 miles, although I dare say there were a few over 60. I did London to Brighton a few times in the 1980s.

I was wrong, and I find that I referred to Imperial Eddingtons in a previous thread, which I think is shocking.
We did develop the Millimole number, which was like an annual Eddington.
And the Spooner, which is simply the number of 1000km rides you've done.

I've imported the data since 1/1/2007 and my Eddington number for the period stands at 67: I've cycled 68 miles or more on 67 occasions. The 68th ride is under 68 miles (67.67).
Before 2007 I was using the old Cyclogs site, which seems to have gone for good. I had at least 2 70mile rides in 2006: my first 100k audax, including riding to and from, and my first FNRttC. I think there was one other, in the December.
I took a sabbatical from 1987 to about 2004.
In my pre1987 cycling, I know I had 1 imperial century under my belt, and probably a few other >70 mile rides. I used to do quite a few CTC Sunday runs, almost all of which would have been in excess of 60 miles.
I reckon my true Eddington Number is therefore about 70.

It has occurred to me that my age is rapidly approaching my Eddington number. As of next week, the difference will be 12.
What is better  to be able to increase your Eddington Number when your age exceeds it, or to push it into 3 figures so that you never need to worry about it?
Actually, I think I'd like to keep my Eddington Number in excess of my age by 12 years. That's quite a complicated aim, as if I decide in my 59th year to do enough >71mile rides to knock out all of those between my provable Eddington number (67) and what I believe it to be (70), I'll have to ride that distance 17 times. The following year, to get it up to 72, I'll have to ride >72 miles 18 times. I suppose what I need to do is ensure that, during the next 12 months, I ride 17 days in excess of 71 miles, but each one incrementing by one mile, to make an investment for future years.
If I decided to ride (say) 10 100mile days, although that would push my Enumber much higher much sooner*, that would take away the incentive, as I get older, to keep the rides ticking over. It would be a great achievement to push my Enumber into 3 figures when I'm approaching 88!
*Not strictly accurate as, of course, it's not as simple as that. However, I've got 82 100mile rides to do to get my Enumber into 3 figures. I suppose I'd better get on with it.

Mine is about 126. I've not totalled enough 300+km brevets or 300+km days in longer brevets to get it noticeably higher yet. With luck it should eventually get to around 200.

My guess is that there are loads of audaxers with an Eddington number of 126, since the 200k ride is their staple diet and lots of them drive to the start.
All but one (I think) of my very limited number of 200k audax rides have been in excess of 130 miles as I used trains to get to the start, and that also included crossing London. That one exception is the only one I drove to. I'd never drive to/from another ride as long as that: my legs cramped so badly just after I set off for home that I could hardly change gear.

Thinks... shall I start a new thread?
Hands up all those whose Eddington number (miles  as defined in the original version) is greater than their age ?
Mine doesn't yet, but it will if I complete my RRTY....
As for the numbers up above 120... and therefore likely to include some 400km rides, how do you log your miles if the ride goes past midnight?

Per 24 hour day, rather than per multiday ride seems appropriate.
I know a bloke who doesn't like to enter anything shorter than 600km because his average brevet length is about 595km.

As for the numbers up above 120... and therefore likely to include some 400km rides, how do you log your miles if the ride goes past midnight?
I log rides over 24hrs as between sleeps, so a 600 is 2 rides before and after a sleep stop.
I think my number is between 70 and 100. I doubt very much I've done 126 200k+ yet, for all I'm a points chasing fiend.
(And that's greater than my age, by more than 20, whatever the actual number is).
This year so far it's 49. I CBA to look back to when records began.

All my 200k audaxes have been within the same calendar day.
I have always regarded the Dun Run as a single ride, because it is encompassed within a 24 hour period. I think, without checking, that I log it to the Saturday because that's when it started. I certainly don't reset the computer at midnight.

Some of my 100k rides have spanned two calendar days (just), as I include the riding from home to the start of an FNRttC. But the ride is always completed well within 24hrs, and before I go to bed. I do sleep on the train home usually, but don't think that's enough to separate it. I don't think I'm likely to do any rides which cover more than 24h startfinish, so I'm reasonably happy with my parameters.
And my Eddington is lower than my age at the moment, but has increased significantly since Butterfly got a Ti bike ;D

126 miles
It's probably not coincidence that this is very close to Randonnee distance :).
Hmm. I've not worked this out. I don't think I have ever done 200km unless part of a randonnee, so the number should be the number of randonnees I've ridden, plus the two 600s I've DNFed. So my number based on that alone is at least 97 (miles). I have done a few >100 mile days outside of Audax, so I can reasonably claim E of 100, but not much more.

101. Its been 100 or 101 for quite some time and it will take a while to get me off this mark as I seem to collect century rides.

I've found this interesting. Thought my number may be quite low, but it's about 70, which is more than my age. I've never chased mileage per se, but just like going out for a ride and seeing where I get to. In fact recently I don't really log miles closely but only keep a rough guide for maintenance purposes.

My recorded rides still give an Eddington no of 68. I have just added the Dun Run to my collection and have now completed 18 century rides.
My problem is that I have 10 recorded rides between 68 and 70 miles. It's going to take me a while to get my Eddington number past 70. ;D
I have recorded 171 rides in excess of 50 miles, all in the past 7 years or so.

A little bit of SQL tells me mine is currently 42.
Less than my age, but only just.

HK and I think that teethgrinder might be one of the few folk with an Eddington number close to 250.

Mine is embarassingly low. To be honest, I'm just amazed that it's in double figures (albeit only just).
Onwards and upwardsonwards...

Must be 102 now. Onwards and upwards.

Just checked mine from my MCL records and its 48 (imperial) and 57 (metric)
I need five, 50 milers to reach 50 (imperial)

80
I have cycled more than 80 miles on 80 occasions (over 100 miles on 69 occasions...they do start to add up don't they?)
It would be more like 90 if I divided my longer Audax rides into separate days.
Oh dear...E=100, another challenge on top of 1mph average I need to chase.
That means another 31 x 100 mile rides. 3xRRTY I suppose.
John Spooner has ridden most of the very long Audaxes many times, his E must be high.

My ride on Sunday increased my Eddington number to 69.
What a position to be in!
I have 6 recorded rides of 69.nn miles, so I doubt that I will be shifting it again in 2012.

My EN is 44.

Mine is currently 63 :thumbsup:

I'm not sure and I can't seem to get the Polar site to spit out it's info in a useful fashion. Did manage to export to xml at one point but it seemed to have a number of duplicates of certain rides.

It has occurred to me that my age is rapidly approaching my Eddington number. As of next week, the difference will be 12.

Made it !

I only have a record for this year, so for 2012 my Eddington number is 54. I can get that up to 55 though before the year's out.
I plan to increase it significantly next year :)

I think my Eddington Number might be slightly higher than I thought. It's the number of miles ridden in a 24hour period, as I understand it.
I have found a few days which seem to have slipped through the net because I've gone out on one bike and ridden 60+ miles and then later gone out on the tandem and ridden another 10 or more. Different rides, same day, total over 70 miles. I shall spend a bit of time sorting that out I think.

Like all good numbers it invites some debate over definitions. I've worked on the view that events like ParisBrestParis are single rides, even if they take multiple days, because the event is based on a single time limit. This would be different from, lets say (as I haven't done it) Lands End to John O'Groats which I would do as a series of daily rides. Where I've been out on a club run and then, as an afterthought, gone out with my sons for a leisure ride I've seen this as two rides, whereas a daily commute I see as one.
If I used the definition in the quote above then my Eddington number would go up as Audax events such as LEL, PBP and the Mille Miglia would become 3 100+ mile rides or even 4, and quite a few of the 600km events I have done would have had 100+ miles in two consecutive 24 hour periods. It would be difficult to do the calculations as I only record the total distance for the event not the point at which I got to after 24 hours. A guess would be that it would move from 101 to about 110.
However, will stick with the way I've calculated and appreciate the beauty of its mathematical uncertainty. I hope that Arthur Eddington would approve. ;D

Just run Butterfly's numbers (as a byproduct of doing something else):
Eddington Number: 41
Eddington Number (2012): 34

...

My personal view on this sort of thing is that it comes down to doublecounting. If I want to brag about "a 1200km ride", I can't then also bump up my 100km count by 12. I couldn't live with myself <wrings hands>.
_{(A bit like how I can't claim a 700km audax if I just happen to ride 700 in a weekend, having entered/declared a much shorter ride. Of course, I can still drop the fact into random interweb threads ... )}
I'm sure there are grey areas I haven't considered/met yet.

Me:
Eddington Number: 43
Eddington Number (2012): 36
Overall figures (as for Butterfly) are for 1/1/2011 onwards

Just checked mine from my MCL records and its 48 (imperial) and 57 (metric)
I need five, 50 milers to reach 50 (imperial)
Currently 50 (imperial) and 61 (metric) :)
(all data since I started logging in July 2010)

Like all good numbers it invites some debate over definitions. I've worked on the view that events like ParisBrestParis are single rides, even if they take multiple days,
The definition commonly attributed to Eddington is quite clear (and different to your interpretation)  "the number of days a cyclist has cycled more than E miles"
Indeed it includes no reference to "single rides" so for a ride to work in the morning and a ride home in the evening would be combined into the total for that day.

Agreed, Saturn. I think that the only question remains over the definition of a day.
I consider the Dun Run, which is a ride done without a sleep break, to be within a 24 hour period and therefore allowable for Eddington Number purposes, even though it starts on a Saturday and finishes on a Sunday.

I just go for single ride lengths. It's rare that I will post two rides in the same day and if I do then they are usually too short to worry about.
This approach is taken for the simple reason that it makes calculating the result easier in excel, rather than any sense of it being more right than any other method

My number would be a lot higher if I were to count a day's commutes as one ride within 24 hours, but that's too fiddly, so I just live with the number I have :)

I reckon Eddington would be OK with Wowbaggers 24 hour days but other measures surely deserve a term of their own because they can't really be called Eddington numbers if folks find it more convenient to make up their own definition ::)

Well I take commutes as being two rides as that's how they've gone into my bike computer and thence onto the Polar website.
After a bunch of shenanigans getting the data out of Polar in a useable format I believe my Eddington number to be 32. That is if every ride over 32 miles counts towards the n for 32. If only rides between 32 and 33 miles count then my Eddington number is far lower.

You are almost certainly more correct than me  however  I will stick with my calculation 1) as it coincides with my personal cycling log that has been going since 1997 and so would be impossible to rework, 2) it avoids the difficulty of trying to calculate (for example) where I was at midnight on a 24 hour TT, 3) it will be a conservative estimate of the number, and 4) it doesn't involve double counting ;D

That's fine but it wouldn't be right to refer to it as your 'Eddington Number'  let's just call it your 'Crazy English Number' ;)

I've amended my signature... :thumbsup:

This gets a little bit brainfrying. I've looked at the multiday continuous rides I have done:
8 600km Audax rides, with at least 200k done on two consecutive days
2 24hr time trials, with at least 300k done on two consecutive days
The Mille Alba  200 miles or more on 3 consecutive days
Paris Brest Paris x2. Each of these had 200km+ on 3 consecutive days. Technically with the 4pm start in 2011 I did over 200km on day 1, a further 400km to Brest on day 2, 400km to Villaine on day 3 and 200km to Paris on day 4
LEL  200km+ on 4 days (the 5th day was a little under at about 180km)
Mille Miglia  200km+ on 4 days  the first "day" was only 3 hours and we only did 120km on the last day.
If we use an Eddington number calculated on the basis of what was done on a Calendar day  this would give me an additional 22 rides of 200km (124.5 miles or more)  which would make a dramatic improvement to my Eddington number (imperial) from 102 to 118. Its much more difficult to work out what it would do to the metric number as several of the 400km rides I have done spanned 2 days and had between 136km and 200km on the second day. However, at the moment it would be fairly safe to say it was in the region of 161 due to the milestonedriven cluster of rides I've done of that distance or slightly over.
I guess, however, that Sir Arthur wasn't in the business of Audax or 24hr time trials and therefore did not have this conundrum. At midnight on a 24Hr time trial I wouldn't be able to tell you what road I was on let alone how far I had gone.
And, if we take Wowbagger's suggestion of a 24 hour period it gets even more difficult. At least it resolves the 24TT situation but for the long Audax rides, especially the 600s I have no idea how far I would have gone at 6am on the second day as typically I would be halfway through the first stage after the sleep stop and wouldnt have a proper time of departure from the first go.
So, I'm going to stick with the way i've calculated it and know that on a strict definition the results are higher.
By the way  a 114 mile ride today has improved it per my calculation ;D but I guess would not under the strict defintion. :demon:

Once an accountant, always an accountant ;) (takes one to know that)
Chapeaux on your true E number Sir (and for working it out) :thumbsup: Eddington presumably would have devised a watertight definition if he'd have realised that one day some cyclists would ride such crazy distances on such crazy timescales. You don't need to worry about metric by the way, I don't think Eddington mentioned that.

Oh the perils of doing a quick calculation! :demon: I simply took 23 rides out of my list in revising the Eddington calculation. So that had 102 rides more than 118 miles! But the Eddington number has its subtleties  118 is 118 rides of 118 miles. And I can't claim that. Its more like 110. :(
Never mind. I will stick with 102 and have to do 5 rides of 103+ miles to increase it, so that should be by the end of May. After that it starts to get easier as I get past the cluster of rides just over 100 miles and it will be a while before I get to 125 x 125 which is where I hit the 200km Audax distances.
Then I might revert to a previously set target. When I was young my ambition was to be a cricketer  around about the time that Messrs Cowdrey, Amiss, Boycott, Zaheer and others were reaching 100 first class centuries. I passed that milestone on the bike in 2011 and so the next one is Jack Hobbs first class record of 197.
You're right. Once an accountant.....
(although large quantities of Smirnoff are reputed to help)

I've been tracking my Eddington number for a while now (http://www.buttonsofmymind.co.uk/eddingtonnumbercycling/). Using the definition of days as calendar dates I'm currently E56 (imperial) and my next target is E60 (I need 11 rides >60 miles). In metric I'm E79 but since it's not equivalent (100 days of 100 km is harder than 62 days of 62 miles) I've never looked at the metric version before :)
John

Since Eddington himself used imperial, I don't really see that the concept of a "metric" Eddington number is of any value.
Why doesn't one of our august number of metric enthusiasts "invent" it and name it after themselves? :P

Metric could be called your Kiddington Number.

Yesterday I invented the Knumber which is the number of calendar years, K, in which you have ridden at least K,000km. I think mine is about 6.

A whole new way to play with a decade'sworth of data. :)
I spent a happy evening discovering that my Eddington number is 94. If all goes well and I finally complete a RRTY, I should get it above 100. It's a motivating thought for this time of the year.

Strange to discover that we've been carrying out the same exercise in parallel :) I only had 3 years of data to work with and I'm currently sitting at 71.

How about the Fnumber, which is based on Furlongs. Allows a decent score  mine would be over 400 :smug:

Or the FFF number (http://en.m.wikipedia.org/wiki/FFF_system), which would denote the number of fortnights in which you have cycled FFF furlongs and also consumed FFF firkins (of beer; or, if metric, of wine).

Strange to discover that we've been carrying out the same exercise in parallel :)
I've kept weekly and cumulative annual total distances since late 2003, when I got back into riding seriously, but I didn't have the individual ride distances needed for the Ecalculation all in one place. So I went back through diaries, AUK records, blogposts, GPS tracks and memory to create as good a list as I can of all my rides of over 100 km, right back to my first century ride (ArdgayLaxford BridgeTongue, solo, aged 16) and including a 7day LEJOG, Raids Pyrenean and Corsican, WellingtonAukland (NZ) and holiday rides in France, Italy and Germany,
Happy memories. If I ever have to stop riding, I'll be able to relive them all. Meanwhile, more living to do: LEL and the Raid Alpine planned for this year.

I can't believe that I'm seriously considering dredging back through the records, adding up daily totals, and converting to miles before sorting and counting...

I'm trying to fight against the temptation to do it.
(Putting it on my Jobs List will probably secure the win.)

I can't believe that I'm seriously considering dredging back through the records, adding up daily totals, and converting to miles before sorting and counting...
49 (data only back to 2009)
One ride required to get to the magic 50. Six rides for 51...
But at least I now have a spreadsheet for entering any daily totals over 80km. And just 98 imperial centuries to get to 100 :\

How to work out my Ed# using a spreadsheet? ???
I've a column of numbers from 1 mile to 177 miles, 2098 entries deep. I think my Ed# is somewhere between 67 and 81.
What do I need to get my spreadsheet to do to work it out accurately?

You need to sort them in descending order of distance, then read down to find where the row number (assuming no header rows) and the distance converge, and read off the lower distance value (rounded to whole numbers, natch).

I was expecting a majick formula! ::)
My E = 76. Five rides of >77 will mean E = 77.

Here you go:
In column A have a list of your rides in descending order  Name this range (the whole column) 'Dist'
In column B put this formula =IF((COUNTIF(Dist,">=" & A2))>=A2,(COUNTIF(Dist,">=" & A2)), "n/a") and copy the formula down the whole list
Look down column B and the first number returned after a load of n/as should be your Eddington number (if your rides are sorted in descending order)
This formula assumes that you have column headers in row 1

You need to sort them in descending order of distance, then read down to find where the row number (assuming no header rows) and the distance converge, and read off the lower distance value (rounded to whole numbers, natch).
I was expecting a majick formula! ::)
My E = 76. Five rides of >77 will mean E = 77.
Here you go:
In column A have a list of your rides in descending order  Name this range (the whole column) 'Dist'
In column B put this formula =IF((COUNTIF(Dist,">=" & A2))>=A2,(COUNTIF(Dist,">=" & A2)), "n/a") and copy the formula down the whole list
Look down column B and the first number returned after a load of n/as should be your Eddington number (if your rides are sorted in descending order)
This formula assumes that you have column headers in row 1
Modifying that formula for OpenOffice Calc gives an Eddington number 1 too great for me. The first row with a number is the row under the actual Eddington number row. I've altered it just to take 1 off the return if the statement is true and it works OK.
=IF((COUNTIF(Dist;">="&D2))>=D2;(COUNTIF(Dist;">="&D2))1;"n/a")
My distances are in column D starting in cell D2.
The way I do it is just to create a column adjacent to the descending distances with the numbers 1,2,3,4 etc. down it. You can just drag down the sequence to fill in the column. This number is the Eddington number in the last row where is still less than the distance.
i.e. in my table the relevant section looks like this...
NUMBER DATE RIDES MILES
52 01/02/09 1 57.8
53 25/07/09 1 56.8
54 31/08/10 5 56.6
55 04/01/09 1 56.2
56 31/05/11 1 56.1
57 22/05/10 3 55.8
58 29/05/09 1 55.3
59 04/06/11 1 55.1
60 29/05/11 1 54.9
So my current Eddington number is E56.
I just add new rides to the bottom and sort columns B to D on distance descending leaving A as it is. Thus my Eddington number will increase to E57 once I've done 5 more days of more than 57 miles (I need to wipe out the 4 days of 56 and a bit miles and also do one more to bump the rows down to 57).
John

I went for a slightly different countif.
Put the distances in column A, a set of ascending numbers in column B, and then this formula in column C: 
=COUNTIF($A$2:$A$1000, ">="&B2)  Headers in row one for this
Copy the cells down in column C (so &B2 becomes &B3, &B4 etc.). At the highest number where Column A and Column B read the same number, that's your Eddington Number.
eg: 
Ride Distance Count
1.2 1 5
3.8 2 4
2.6 3 3
4.9 4 1
3.1 5 0
Eddington number here would be 3

Why?
Eddington had a simple system  count up the number exceeding a certain distance. Reading the row numbers on a spreadsheet gives us that without any fancy calculations (well, other than the one converting my km into miles for the reference column).
Could. Not. Be Simpler. Why complicate things unnecessarily? Surely Eddington, as a scientist, would frown on anything beyond the simplest method required.

That is all the formulae are doing. It's not fancy, just automated.

Since I've done more than 125 200km audaxes, without spending any time calculating, my Eddington number must be about 125

Since this is about miles completed in a day it's going to be bloody hard to get beyond 200 regardless of who you are.
Maybe a regular RAAM contestant may rack up 200 miles a day 200 times as part of training and RAAM itself but it gets increasingly hard to raise your number.
E=100 would be easy for me, my prep for PBP2015 will get me there.
I suppose, if I keep doing 200km Audaxes, I'll end up like Phil d with 125 but there's a significant drop off in the number of rides over 200km I've done. Getting to E=125 would be fairly easy over the next couple of years but getting to E=130 would be a significant undertaking.
I reckon E=>150 is an exclusive club.
Best just to turn all your rides into 200 milers at an early age.
Given that this is about miles in a day rather than rides I reckon I'll break my 600s and PBP into separate days and claw back a few more E's

Plain Eddington is a lifetime measure, favouring those who've spent years in the saddle as well as those who cycle prodigiously in their youth.
Having calculated plain E for getting on for 10 years or recorded rides, I'd like to calculate what it was at the end of each of those years; and what it would take to maintain it over a rolling period of n years.
The first would give me a satisfying feeling of progress; the second would give me an incentive to keep riding at least as much and as far in years to come as in my better years so far. That feels like a better target than chasing an everharder higher E (though it would be satisfying and achievable to get to E = 100 by the end of this year).
What I'm thinking, and the approach of splitting 600s to rack up a few more Es, suggests that Goodhart's Law (http://en.m.wikipedia.org/wiki/Goodhart's_law) applies: as soon as you use a measure as a target, it starts to influence the behaviour it was intended to measure, with sometimes unintended consequences.

Like thinking "I've only got time for E miles today, hardly worth going for a ride"

Having calculated plain E for getting on for 10 years or recorded rides, I'd like to calculate what it was at the end of each of those years; and what it would take to maintain it over a rolling period of n years.
Some sums later...
 Oct 2011: E = 93
 Oct 2010: E = 84
 Oct 2009: E = 68
 Earlier years: unknown, as my individual rides list only captures rides > 100 km
If I do my planned rides this year, E will get to 100. If I want to keep it at 100 on a rolling 10year period, I need to do (obviously) an average of 10 century rides a year, so the equivalent of RRTY each year would do nicely. A couple of years of that, and I'd get to an alltime E = 125 and then, because most of my long rides are 200 kms, probably not a lot further.

Whilst we are discussing formulae etc... I'm sure there's a simpler bit of SQL, but the following works for me:
sqlite3 html bike.sq3 <<EOF
select cast (t.distance as integer) as eddington_number from times t where cast (t.distance as integer)<=(select count(x.distance) from times x where x.distance>=cast (t.distance as integer)) order by t.distance limit 1;
EOF

I'm new here, but I reckon I've ridden 64 miles more than 64 times.
So 64 it is.
I don't think its going to get any bigger than that.
The E number would be a similar concept to the N number.
How many minutes one can keep up N mph. 26.2 anyone?

Oh, easily.
You did mean downhill in the Pyrenees with a tailwind, didn't you?

I've only got around 6 or 7 years of rides recorded, but then I don't suppose I did anything prior to then to confuse the calculation anyway!
I'd guess my number is around 70 but if I remember next time I open up Cyclistats then I'll confirm that.
I like the K number stat too. I reckon mine would be around 5; 5 years of more than 5000km. Reckon I'd make it 6 this year, all going well.

Mine is still firmly at 43, but I thought it would be interesting to see how it increased with time. A little Python script later revealed the following (bah  just noticed the US date format on the xaxis .... #broken  fix later):
(http://www.oakden.org/mark/bike/yacf/pics/en_by_time.png)
My aim is to get it to 50 this year... 14 rides of >= 50 miles required for that though.

If one consistently rides 100 miles, the first ride will result in an E number of 1 due to the number of rides and not miles. The second ride will increase the E number to 2, due to two rides ridden.
This will continue until the 100th ride, when the E number will be 100, Bingo 100 rides of 100 miles.
Another 100 mile ride will result in the E number remaining at 100 due to distance, not number of rides.
A ride of 101 miles will now increase the E number to 101.
A ride of 125 miles will stabilise the E number at 101.
Another ride of 125 miles will increase the E number to 102.
The E number does not, a/ indicate total miles ridden. b/ indicate total number of rides ridden. c/ indicate the longest ride ridden. d/ indicate average miles per ride.
It is a statistical nonsense.

The E number does not [do anything useful]
It is a statistical nonsense.
Your point, caller?
I didn't think it pretended to be anything other than a slightly silly bit of fun (and a demonstration that anyone who's got a high E number has cycled quite a lot).

I think it's interesting, and not silly. It doesn't have to be useful. Though, interestingly, it is: as a time series, like Oaky's, it offers a summary of a longdistance cyclist's development, quite economically and in a way that complements the other summary measures Ningishzidda mentions.
I'm not attracted to the equation "not useful = nonsense". That would create a lot of nonsense.

Agree but if one person finds it interesting and is encouraged to go for one more ride or ride for one more mile, how could it be either?

A ride of 101 miles will now increase the E number to 101.
No it won't, it will need another 100 rides of 101+ miles to hit E=101 (http://www.nrtoone.com/forum/images/smilies/cycle.gif)

True. That's what makes it stupid.

It's a really interesting measurement.
I am not a recorder of miles  until this year when I will give it a go. (I do have records of each audax I have ridden though).
Since I started audax (late 2010), I have around 47 days of 100 plus miles. Prior to that, I'd only have half a dozen or so 100 mile days.
So  without going into too much maths and guessing (as there's quite a few 100km rides)  my number would be around the low 50s.
I'll just revisit the whole equation in a couple of years when all being well, I'll be able to prove 100 days of 100 miles. I suspect that like most audaxers, I will, sometime in the next few years, hit 125 and there it will stay.

If you keep doing the same ride, you'll hit a ceiling. If you vary your rides, your progress is likely to continue for longer. Eddington was mainly interested in having a bit of fun playing with numbers.

Most 200 Randos are over 125 miles. When you ride your 126th 200 Rando, you might likely get a 126 E.
Will it be dependent upon the shortest 200 Rando you ride?
Bad luck if you rode a 200 Rando that was bang on 200 km ;D

Yes.

The typical 200k Audax that I've done has ended up at around 130 miles  DIY perms are usually somewhat overdistance as are most of the calendar rides. It also helps to ride to and from the start of local Audax rides (my Kennett Valley Runs have ended up at about 150)  so I'm expecting my E to get stuck in the mid130s...Eventually... if I keep to my current riding patterns. Much higher than 160 seems inconceivable unless you Teethgrinder.

Does anyone know what Eddington's Eddington Number was?

84

Are people forgetting this is just harmless fun. Being at 100 exact, I'd hope that the next significant milestone for me is the 126 (200k) marker.

Does anyone know what Eddington's Eddington Number was?
What about Tommy Godwin's E#? It must be around the 150  180 area!

Given that he averaged 200mpd for 500 days I would assume something like 220. Unless you consider it to be all one ride and therefore it would be a lot smaller :smug:

I understood the Eddington Number to be based on miles per day. I don't know if Eddington did overnight rides and how he counted them, but I count them as a single ride within a 24 hour period not punctuated by going to bed.

I worked this out a while ago (and still have the spreadsheet). Currently it's 91, but I need another 25 or so rides of 100 miles to get it up to 100. I have done a lot of rides in the 90s without bothering to do the extra turn around town to get over 100.
Like CET, I've not worked out separate days on longer rides, as that would involve going through brevet cards and guessing, which hardly seems to fit with Eddington's concept. For example, I'm not counting rides before 2005, which is when I started to keep records.
It may not meet with the idea of a day's riding, but it is accurate, and consistent, and a bit of fun. Maybe I should only ride 300 km and above from now on...

Well my stats are a bit out due to Audax days going in as three rides, the ride to the start, the Audax proper and then the ride home.
I guess I can either change how I log things now or given that I can export a csv file I wonder is there's a way to automate totting up all rides starting on a day into one total?
ETA: Except, I guess, commute days as that seems like a bit of a big gap between them to count as one ride ???

My Eddington Number went up to 46 today.
:thumbsup:

D'oh. Didn't see this before. In Excel, what you want is a PivotTable with the dates down the left hand side and a sum of the distances in the data field.
If anyone needs some Excelfu, feel free to PM.
Worked out mine last night, which is up to a (good for me) 25. Onwards and upwards!

I've lost track of my E number but I've done 70 rides of 100 miles or more so it's at least 70.
I'd like to get it to 100 but 100 miles is a long way. I may get back into RRTY.

I just checked mine and it's 56 at present. Up from 48 in September which I'm quite happy with.

I have three >80 mile days to my credit in the past month or so, which has ensured that my Eddington Number is demonstrably not less than 69. I have four more rides to do over 70 miles to bring it up to that number.

I can't really give an exact number, but given the miles I've done so far this year
I must be around 75 now, and with my current training for LEL it will rise.

(I'm still trying to stave off the temptation to work mine out!)

I’ve increased mine this year by around 5, having done 200k x 3, 300k x 1, 600k x 1. So probably pushing 110. Soon it will reach 125, and it will get stuck there for ages.

104.
Since records began in 2009.
I suspect I'll get to 127 this year, and, like simonp, (and most randonneurs) it will then stay there for, well, ever. I can't imagine doing another 163 300k+ rides in my lifetime.

I probably have around 50 days significantly over 200k. I’ve done LEL, which equates to around 5. PBP x 2 another 6. 11x600k another 22. I’ve done around 5 400s, so another 5, say. At least 10x300k, so that gets to around 48, two 600s which I DNF’d, another 2. Plus one 144 mile day before I’d done my first 300k, and add a few 200s which I rode to/from, and we’re looking at pushing 55. So I only need another 75 or so to push the number significantly above 125. Ok, so actually it’s not very likely.

Mine seems to have increased from 126 to 130 since I last checked.

Mine is stuck on 102, as I've 5 rides at this distance, still have 3 103+ mile rides to make it go up. So am working on the metric one which is easier to do as its got into that space between 128km (80 miles) and 161km (100 miles) where, unsurprisingly, I don't have many completed rides. It went up to 137 on Monday courtesy of a spectacularly hilly romp around the South Downs and the greensand hills north of Midhurst and Petworth.
On a tangent, looking at other possible units of measure  a furlong is almost exactly 500 kilometres. I've kept a log of "long" rides  anything over 100km, and, at current rate of progress should have a lifetime Eddington number of 500 in furlongs by the end of 2016.
I still haven't split up my multiday events  as I've no idea exactly what distance I did on each day of most of them.

Has anyone looked at climbing figures?
(in the spirit of Strava and Brailsford)
At a rough guess, Nx100ft might work best.
_{p.s. CET: I don't think a furlong is even close to 500 kilometres!}

There's 8 furlongs in a mile, and a mile is about 1600m, so a furlong must be about 200m.

So 500 furlongs is about 100 km, and CET has ridden over 100 km 500 times. What's complicated about that?
I think I'll stick with miles.

My youngest son is by no means a cyclist.
We went to a drag race meeting at Avon Park Raceway and I happened to have one of my bikes in the back of the car.
After the motor racing had finished and the race meeting organisers had packed up their timing equipment, we got my bike out of the car and had a ride up and down the drag strip.
My son rode one 1/4 mile and was knackered. He rode no more.
HOW is an Eddington number of 0.25 achieved?
HOW can a person ride 1/4 of a bike ride?
Successfully debunked. :o :facepalm:

My youngest son is by no means a cyclist.
Evidently.

Since it works on integers, N jr has an Eddington Number of zero.
Undebunked.

Back from a long weekend (in every sense: three days, including the longest, and >250 km each day), I checked my Eddington number again: it's exactly 100, which is quite satisfying.
If all goes according to plan, and counting LEL days separately, it'll be 102 by the end of the year  twice my age. And then my age will increment...

After Saturday's Tan HIll ride (102 miles) I'm still two rides short of getting my E number up to 70, 40 rides short of getting it to 80, 76 rides short of getting it to 90 and 80 rides short of 100.

I'm currently at 46 and my aim for this year is to get mine up to 50  I'm 7 rides away at the moment. It'll take more than 20 rides to get to 56 though.
(http://www.oakden.org/mark/bike/eddington20130710.png)

Mine, being so low, has shot up (relatively) quickly  from 2 at the start of 2012 when I started logging my mileage, plateauing at 20 over the winter and is now up to 28.
Hopefully there'll be some more quick wins over the next few months, as more of my weekend rides are in the 50100mi range. My first goal is to get it higher than my age (I'll be 30 next year and then keep it there :thumbsup:

As soon as your E number is in excess of your age, sit back, relax and laugh at everyone who is still struggling.
The way to do this is to start riding Imperial Centuries when you are still at school, and continue to ride three or four per year until demise onsets.
Before AUK was around, the CTC was a good source of encouragement.
Starting this venture in your twenties will require a clutch of six or eight century rides per year until you have reached the relaxation point.

10 years and 4 months of an RRTY will put your Eddington number at 124.

16 years 8 months with a generous 300 RRtY will get you a cool 200.

Sir Arthur would be happy  he reached 84 and popped his clogs at 61, thereby retiring with an E number greater than his age.

My Eddington number is already more than 2.5x my age. When should I stop? I doubt I will live long enough to overtake it even if I stop now.

Get out of bed earlier.

Since I last posted I have had another small operation to finish my nose reconstruction  just 10 days off the bike this time  and have, after a further 5 rides, managed to get my E Number up to 47.

My Eddington number currently exceeds my age by 11. I suppose my ambition is for my age eventually to exceed my Eddington number.

My Eddington Number hasn't shifted for a while, and lags behind my age a bit.

(I'm still trying to stave off the temptation to work mine out!)
I gave in and displaced important jobs, to discover that:
My E Number (miles) is 139. Big contribution from DIY 200s, which usually have a lot of extra distance (mine do, anyway).
One more 140 mile ride will get it to 140.
Eleven more rides of 141 or more to reach 141.
but 68 more of 150 or more to reach 150.
Edit: I acknowledge the advantage of having had 71 years to do it in!

My Eddington number currently exceeds my age by 11. I suppose my ambition is for my age eventually to exceed my Eddington number.
Actually, it didn't. On that date, one month after my birthday, it exceeded my age by 10.
I quite like my Eddington number being 69. It's nice position to be in.
I need two more rides to bump it up to 70. I think I will plan one of those for halfterm.

Today's total was just over 71 miles. One more ride to get to an Eddington number of 70.

As a new convert to Eddington (as in today), mine is 43, from a total of 15,200 miles since I started logging rides (2009).
Six more rides and I can increase it to 46......I can see this taking control of me now!!!
:facepalm:

Oaky keeps trying to explain this to me. For a while I thought they were called Erdington numbers and I wondered whether they had anything to do with a district of Birmingham. I am dimly aware of Erdington as my cousin Big Rachel lives there. Actually, I'm not sure she does any more, I think she lives in Great Barr now.
Anyhow, Oaky is wasting his time (although you have to admire his tenacity) as I am (a) not remotely interested in E numbers and (b) even I was I'm too thick to understand.

An additional two Eddington rides last week puts me at E=59. Another three needed for E=60, which I should manage over the Xmas hols.
A target for next year is to get to E=70 which will require another 38 rides of 70 miles+.

I have one more ride still to do to be sure of reaching an Eddington number of 70. I think it is highly probable that I have some unrecorded rides in excess of 70 miles from the 1980s but of course they don't count.

Hmm. Not going to recalculate from scratch but since last time 200 + 300 + 400 + 600 + 1400 takes me to around 115 I think.

Just processed my logs from 2006 to date and calculated my E number as 155.
You can tell it's Christmas day.

There was a bit of 'rubbish' in the news recently that purported riding a bicycle for one hour extends life by one hour.
How do I convert my E number into months of extra life? And IS it useful ???

Its easy.
( ( E^2 ) / S ) / 24 = Days extra life, where S is average mph.
When S is 12 and E is 60, Days extra life is 12.5.
Open to Peer review ;)

Not sure this works as it doesn't factor into account all the nonEddington rides that you do and their contribution to extra life. Also  Tommy Godwin in his recordbreaking year would have racked up about 200 days worth of extra life but the effort probably shortened his.... I suppose according to the origianl assertion if you never stopped pedalling you would never pop your clogs  so you'd have the key to eternal life (as long as you never stopped) :facepalm:

My Eddington number for running is now 14

Have managed to put my logbook into Excel which means that i can now work out in year Eddington numbers. Each year shows the total distance (miles), the number of rides, the inyear Eddington number, the lifetime Eddington number (this was understated until 2011) as there were some longer rides before 1994 when I didn't have complete records. I also calculated the median and average distances in each year. 2003 was my first year of BR Audax rides, 2005 my first SR series, and 2007 my first 1000k+ ride (PBP). 2012 was the year when I commuted most and 2013 I had a lot of overseas travel.

I have one more ride still to do to be sure of reaching an Eddington number of 70. I think it is highly probable that I have some unrecorded rides in excess of 70 miles from the 1980s but of course they don't count.
I did it today, so my Eddington number still exceeds my age in years by 11. Today's ride (78.01 miles) is Number 46 counting down from my longest ride (147.34 miles  Dun Run etc., 30/6/2012). I have now recorded:
193 rides in excess of 50 miles
130 rides in excess of 60 miles
70 rides of 70 miles or more
38 rides in excess of 80 miles
25 rides in excess of 90 miles
21 rides in excess of 100 miles
13 rides in excess of 110 miles
9 rides in excess of 120 miles
7 rides in excess of 130 miles
4 rides in excess of 140 miles
I have 5 more rides of 71 miles or more to do to increase my Eddington number to 71.

I have also been able to achieve that long desired calculation  my Eddington number in furlongs….
It is 457 (that's 457 rides of 57.2 miles or further). However, I still have a further 105 rides of 62.5 miles or more to reach the magic 500. At current rate of progress that should be some time in 2016.

Finally made 50.
It was meant to be last year  that was the only real cycling target I set myself, but injuries, bad weather and CBA meant I failed in my atempt. (Had I realised I was only 6 miles short when arriving at the Essex Xmas do, I might have nipped out for an extra loop... or perhaps not....)
Knocked it off today with a 55 miler circumnavigating Chelmsford.
/me scuttles off to check how many rides I would need to get it to 62 in order to set myself a target to fail to achieve this year...

Congrats Oaky :thumbsup:
Mine, being so low, has shot up (relatively) quickly  from 2 at the start of 2012 when I started logging my mileage, plateauing at 20 over the winter and is now up to 28.
Hopefully there'll be some more quick wins over the next few months, as more of my weekend rides are in the 50100mi range. My first goal is to get it higher than my age (I'll be 30 next year and then keep it there :thumbsup:
Well mine did shoot up pretty quickly after that and hit 31 in August last year, but it has stayed there ever since. I seem to do a fair few rides of about 50km, which are no no longer contributing to an increase in E. Getting to 34 shouldn't be too difficult, but after that it's looking a bit harder.
Longer rides are looking few and far between in my logs  I only have 16 rides logged over 40 miles, and only 13 logged over 50. Lots of work to do this year then!

Reached 101 last weekend.
Need another 6 102+'s to jump up a notch.

72
(but that's based on 72 rides of 100 miles or more so each time I ride 100 miles it will increase all the way up to 100, if I checked in more detail it may be a slightly higher than 72).
Two and a bit RRTYs would get me to 100 fairly quickly.
Since I've done a fair few rides over 100 miles I can see potential for E=103 fairly easily but then there's a big jump to 125 that I can't see me making.
Surely a fair few Audaxers have E=125, 10xRRTY gets you damn close.

I reached E=48 today.
Great ride up to the Teifi Pools  the source of Wales' longest river River Teifi (whole length in Wales that is), that reaches the sea at Cardigan. Highest point reached was 1520 ft with a few hard 20%ers along the way :)
May 2nd. As of today E = 49
June 20th. E = 50 :thumbsup:

Reached 101 last weekend.
Need another 6 102+'s to jump up a notch.
As you can see from my stats above I went from 82 to 100 in 2 years and then took 3 years to get from 100 to 105. Comes from the fact that I've only done 6 90  99 mile rides and about 40 100  109 miles. Funny thing round some milestones :)

I worked this out a while ago (and still have the spreadsheet). Currently it's 91, but I need another 25 or so rides of 100 miles to get it up to 100. I have done a lot of rides in the 90s without bothering to do the extra turn around town to get over 100.
Like CET, I've not worked out separate days on longer rides, as that would involve going through brevet cards and guessing, which hardly seems to fit with Eddington's concept. For example, I'm not counting rides before 2005, which is when I started to keep records.
It may not meet with the idea of a day's riding, but it is accurate, and consistent, and a bit of fun. Maybe I should only ride 300 km and above from now on...
Up to 98! Only 3 more 100 mile+ rides to get it over 100.
I guess the next milestone will be much much harder  only 65 rides of 110 miles or more, only 52 over 125 miles...

I don't have full training logs so can't count most of my early rides (not that there will be many long ones TBH). Currently E=65, only 4 more rides to get it to 67  but then the gaps quickly start to get larger!
I've only recorded 45 over 100miles, so it'll take a long time to get near that! :o
I've only been on the RRTY train for 18 months so far, certainly can't imagine still being on it all the way to E=125 :facepalm:

My 79 miles on Friday night/Saturday morning means that there are only 4 more rides required for me to increase my Eddington number to 71.

I now have 3 more rides of 71 miles or more to make that my Eddington number.
Whilst updating my spreadsheet dedicated to such things I noticed that I have 199 rides of 50 miles or more recorded.
I think we need to do something about that in sociable mode. I will put my mind to it  possibly at Mildenhall!
Edit: soddit! I missed it! I hadn't logged my 59miler on July 20th, the BHF LondonSouthend ride. So I have a doublecentury of halfcenturies.
Actually, there are certainly quite a few more 50milers from my previous cycling existence in the 1980s, which of course I never logged at all so it's all pretty contrived.
Edit 2: I have just sorted my recorded rides into date order and I know of at least two, possibly three, 60milers that are missing. Apart form my only 100mile ride from the 1980s, for which I have a certificate somewhere and which I have attributed to 1st June 1981, the earliest ride I have recorded is the Hopey New Year of 6/1/2007. I can think of two which were well over 60 miles from 2006  my first ever FNRttC which was an excellent night out, and my first 100k audax, Up the Uts.

The Mildenhall 200 took my Metric Eddington number to 150, 150 rides of 150km plus. Due to milestoneskewing stats I've only 2 rides between 150.0km and 160.9km so will need just another 13 160km plus rides to reach the magic 160.
Meanwhile the imperial Eddington is starting to make some progress after passing the bottleneck of just over 100 miles. Another 14 113 mile rides will bump it up from 107 to 113.
The big milestone remains the Eddington in Furlongs  I am just 69 100km rides from reaching the very round sum of 500 (62.5km being almost exactly 500 furlongs). At this year's rate of progress that might be achieved by Christmas 2015.

Surely the millilight second must be the ultimate goal for every E number chaser. At 299.792 km it roughly equates to a standard Audax distance.....something to aim for?

Ha ha. I'm only about 250 short on that count :facepalm:

My metric Eddington number is just a shy above the magic number of 200, 201 at the moment. It'll be quite hard to make serious gains now on the metric Eddington Number front.

Due to CET Junior having extra rugby training had 2.5 more hours today and so went out for a long ride than usual. Result was an unexpected increase in my Eddington numbers to 108 (imperial) and 151 (metric). When I started this year wasn't expecting to add 4 points to the imperial Eddington number so chuffed. But have logged 18 imperial centuries this year (looking good to beat previous PB of 21 in a year). I need 3 more 109+ rides for 109 and 5 more 110+ rides for 110 so those are probably 2015 milestones.

Mine's 100 as of yesterday :D

Mine's 100 as of yesterday :D
Chapeau. A ton of tons. Only if you are like me it gets hard to improve the number from then on due to the cluster of rides just above 100 miles. I've done 49 century rides between Eddington 100 and Eddington 108.

Good one, Deano!

The same problem will occur when you reach the metric 200 mark.

At current rate of progress that is about 15 years away :). Imperial 125 is probably only 4 years away and, if achieved will be while the metric mark is stuck in the low 160s. Fortunately for my Metric Eddington progress (probably in my retirement) I don't actually do a high proportion of my overall audax rides as bare 200s,

72
(but that's based on 72 rides of 100 miles or more so each time I ride 100 miles it will increase all the way up to 100, if I checked in more detail it may be a slightly higher than 72).

Surely a fair few Audaxers have E=125, 10xRRTY gets you damn close.
I've now done 75 rides of 100 miles or more so that's a definite E=75. I should really check how many rides between 75 & 100 I've done
Edit. E=85
I should be able to get to 107 over the next few Audax years (2 x RRTY) but, once I get to 107, my "bank" of slightly overdistance 100 milers rides starts to run out and for every ride I try to add at the top, I lose one at the bottom.
I'll be very happy to reach 100, I think that's not an unreasonable achievement, 100 miles ridden 100 times.

Just reached 102.
Need 1 more 103 to jump to that figure and 4 x 104's to jump to that figure.

If you (and all your rides) are on Strava, there's an app for this: http://canini.me/eddington
It does a good job of adding up all the rides in a given day, but not splitting out rides spanning multiple days. Happily, I generally record & upload long rides in daysized chunks.
E_{Thing1} = 76 [20141113]

Is that all thing1? It seems very low to me? Or just since _{STRAVA} records began?

Is that all thing1? It seems very low to me? Or just since _{STRAVA} records began?
Mine is similarly unimpressive (79) because:
 strava records for me only go back as far as around 2010 (and are not complete since then)
 multiday rides such as LEL which I've entered as a single ride only count for one ride; when I computed it myself I considered PBP to be worth 3 rides of 200 miles ish and LEL 4 of around 180 miles, for instance. I guess the app is not examining the gpx log and determining if a ride spans multiple days. So I could increase the number if I went through and split up any multi day rides, but I prefer to record them as such.

Mine's 129, with 3 x 130 required for 130.
I just don't really believe I've done that many more moderately long days than thing1.
Or maybe his greater speed means he does the same distance in fewer days ;)

I could probably claim over 120 now if I worked it out based only on Audax results.

Is that all thing1? It seems very low to me? Or just since _{STRAVA} records began?
;D Yes I realized I used to Audax without GPS, and there's probably a few touring days over 80miles that won't be on there either. Would be interesting to xref the brevet cards. I don't think I'm over 100 though.
Funny story  thinking 76 was a modest score I posted it on the work biking list and promptly got back praise and congratulations for having such a high number. Including from the author of that app who I didn't even know worked there (a surprisingly common occurrence at my work. Stories include "why does UTF8 work this way?" "why is Java like X?" "what was the phrase used by my MIT CS lecturer in 1980" and in all cases the author of said thing has replied....)

Mr Eddington is a harsh master....SR Series this year plus another ten 200's and I move from E59 to E66. It will take another similar year to move into mid 70's. And I thought I was a cyclist.

Just for fun of itbeing a rather grey cold day here...have accumulated all cycle rides I`ve logged on Excel between 2002 2014;
SCAREY I have ridden 2193 logged rides; about 500 of these are down to a daily 1517 mile commute.
Just under 64 000miles to date
If I understand Eddington correctly my E=79; probably a bit higher over cycling span as have in youthsince aged 14 done several 200km Audaxes (eg Exmoor Grimpeur a couple times, Crossing Desert of Wales ) / and one 400km rides and other longer unlogged (on Excel) cycle routes of over 80 miles
so maybe I`m about E=85??

Got to 103 last weekend. Need x 2 104's and 8 105's.

In audax years mines about E24.
I can tell you're impressed.

The Poor Student took it up to 109. Progress is getting easier for a while now that I have got over the lump of rides that were 100 miles or just over. Only need 2 for 110, 4 for 111, 8 for 112 and 9 for 113, which hopefully will get this year.

just got over 60 rides of 60+ miles. That's over 2/3 years so some work still to do

based on childhood tours, teenage tours, fnrttc and other social rides it should be at least 55 but I have no records to prove it.

Never mind my Eddington number (*), what we want to know is what Teethgrinder's Eddington number is, not to mention what it will be at the end of the year.
*
114, last time I worked it out. I very much doubt it's increased since.

Reached 104. Now need 5x 105's to reach that figure.

110

130  only calculated it recently as a clubmate offered 67 and he thought that I'd be passing that soon. He was quite "surprised" at the figure. Cannot get much higher now  but hope to reach 131 by the end of May.

With yesterdays Oasts & Coasts Audax I have now reached 105.
Need x6 106+ to reach that number.

not doing nearly as badly as I thought.... used that strava thingumywhatsit to work it out for me (which counts my commute as 2x7 mile rides each time)...
According to my Strava data, I've cycled 28+ miles on 28 different days = so E=28 currently
To reach an Eddington number of 30, I need 3 more rides of 30+ miles.
To reach an Eddington number of 35, I need 12 more rides of 35+ miles.
To reach an Eddington number of 40, I need 25 more rides of 40+ miles.
all in all, that means that with what I have planned for May and indeed the rest of the year  I would hope to be E=35 or more by the end of May, and something like E=45 by the end of the year!
:)
quite pleased with that for a relative novice.

Yesterday's effort took me to 111 x 111 rides so a double Nelson or E111.
E111 is also s the disodium salt of 1(msulfophenylazo)2naphthol6sulfonic acid, used as a food dye but banned since 1978 as it was proven to be toxic. And the European Health Insurance Card which might be handy on PBP.
4 rides of 112+ miles are required for the next improvement which, ironically might be in PBP. The bigger milestone, which might just be squeezed in this year is 100 x 200km+ rides. I do myself out of things a little as I count multiday events such as PBP as one ride not 3x or 4x, primarily because I can't be bothered to work out what distance I'd done at midnight.

whoop! just hit the 30 mark.... and only a couple more rides to get to 35...

Currently on E=52.
My E would be higher if I had proper Eddingtoncompliant records (splitting multiday rides such as overnight 300s, 400s and 600s into their dayby day components and combining multiple shorter rides in a day). My notquiteEddington number is calculated over whichever rides I recorded separately... I tend to record an Audax as a single ride, so I get Eddingtonshortchanged on the two day ones. I separate obvious two day trips such as camping into out and back, so those are OK). I doubt the approximation makes a great deal of difference though.
I still need 20 more 100k rides to get it above 62 though!

I would count a day's ride as a day's ride, even if I finished in the early hours. Only if a ride was over 24 hours or contained an hours of darkness sleep, would I count it as two for Eddington purposes.

My understanding of Eddingtoncompliant rides is that they are completed in a 24hour period. Thus, the Dunwich Dynamo, which starts about 8pm on Saturday, doesn't normally finish until boarding a train in Diss or some such, about 20 hours later. Ergo, all 149 miles count.

Hah, I used the calculator on swinny.net and achieved a mighty score of:
26
Ah well, I only started using Strava last year so there's still hope of cracking 50 if I live a very long time :)

This is tough  rode through a harsh Cairngorm winter to get my RRtY and completed another SR Series to see my Eddington number 'shoot up' from E66 to E71. With a number of rides in 70's it's not going to increase much this side of 2016.

My E Number has shot up to 51. Only another 10 rides above 52 for another leap ::)

Mine's 49, based on Strava data  I started using it in December 2013 though, so it would definitely be >50 if I had records of the rides I did before then.

I've done 83 rides of 100 miles or more so it's at least 83.

Eddington is the ramp test of cycling achievements. It gets harder as you go along. I've had 15 century rides this year and it has moved me from E109 to E111. I may just get to E113 by the end of the year. Another 6 or 7 years of Audax might push it as high as 130 and then it will get stuck.
But Eddington can, in theory, be applied to any set of units, which I think would have appealed to Sir Arthur, who tried at one point to calculate the number of atoms in the universe. So the next Eddington goal I have (rather conveniently since 100km = 500 furlongs) is to reach E500f (500 rides of 500 furlongs or more) :smug: I'm on 469 at the moment and at current rate of progress (1 per week) the goal will be reached early in 2016.

Just calculated this for the first time, using that third party Strava app (rides back to 2013), and my excel file of rides going back to 1980s.
The result is: E=42 (need 14 more rides of 50+ miles to get E=50)

Just clicked over to E=53. I need 3 more rides for 54, 6 more for 55, 11 more for 56 and 24 more to get it to 63 (i.e. above 100km)...

It has occurred to me that my age is rapidly approaching my Eddington number. As of next week, the difference will be 12.
What is better  to be able to increase your Eddington Number when your age exceeds it, or to push it into 3 figures so that you never need to worry about it?
Actually, I think I'd like to keep my Eddington Number in excess of my age by 12 years. That's quite a complicated aim, as if I decide in my 59th year to do enough >71mile rides to knock out all of those between my provable Eddington number (67) and what I believe it to be (70), I'll have to ride that distance 17 times. The following year, to get it up to 72, I'll have to ride >72 miles 18 times. I suppose what I need to do is ensure that, during the next 12 months, I ride 17 days in excess of 71 miles, but each one incrementing by one mile, to invest make an investment for future years.
If I decided to ride (say) 10 100mile days, although that would push my Enumber much higher much sooner*, that would take away the incentive, as I get older, to keep the rides ticking over. It would be a great achievement to push my Enumber into 3 figures when I'm approaching 88!
*Not strictly accurate as, of course, it's not as simple as that. However, I've got 82 100mile rides to do to get my Enumber into 3 figures. I suppose I'd better get on with it.
Thinks... shall I start a new thread?
Hands up all those whose Eddington number (miles  as defined in the original version) is greater than their age ?
Mine doesn't yet, but it will if I complete my RRTY....
As for the numbers up above 120... and therefore likely to include some 400km rides, how do you log your miles if the ride goes past midnight?
I need to get my 14x 50+mile rides done within the next year to reach equivalence; Age = E. :)

Another nudge to my Eddington number at the weekend with 123.71 miles of Dun Run.
I now have 68 rides in excess of 71 miles and a further 5 of 70 or more. I therefore need 3 more rides >71 miles to shift my Eddington number.

Friday night's Lun Run took me up to an Eddington number of 39  a nice eightyear buffer in my E>age efforts!
I think pushing up to 40 (five rides needed) will be my last big move for a while, as I've got a lot of rides in the low 40s, and getting to 50  or even 45  will need a fair bit of work. I've got designs on making my E=40 ride a trip to the Berkshire village of Eddington (https://www.google.co.uk/maps/place/Eddington,+Hungerford,+West+Berkshire+RG17/@51.4176015,1.50748,15z/data=!3m1!4b1!4m2!3m1!1s0x4876aca1eb6be4ad:0x89a2819910fa4b90) :D

I've ridden through Eddington many times without ever realising it :facepalm:
I've even used it as a control and called it Hungerford. My most profuse apologies to the community. :facepalm: :facepalm:
Worse still I have descended Eddington Hill many times (on CCB club runs) and never ridden up it :facepalm: :facepalm: :facepalm:
There is only one thing for it. Plan the ride that takes me the next Eddington number up so that the exact Eddington distance is reached in Eddington, going up Eddington Hill :smug:

I have reached E= Age :)
and I'm only 3 rides off 35 too....
I also realise that since the 1st Jan I've ridden 1600 miles  and 1240 of those have been on my new Ribble... which means that in the 6 months I've had the Ribble, I've ridden more miles on it that I did in the whole of 2014.... I'm impressed with myself. My 3 cycling goals for the year (Ride London, Bruno 200 and more miles than last year) I have achieved in just 7 months. :D

15 miles / 19 km at the moment

After yesterday's Around Weald Odyssey my Eddington No. is now the same as Eddington's Eddington No.  84.
Based on typical ride patterns I'll hit 85 by the end of this year, be on a 100 at the end of next year but then it will take me an entire further year to get to 101 :[ I guess, all part and parcel of why Eddington is such a fascinating / obsessiongenerating artefact.

16 miles / 20km now.
Next jump after two 17mi rides, or one 21km ride.
Not sure when I'll jump up to E=18m, but should be E=21k by Thursday  planning an imperial century, provided I recover from not sleeping enough over the weekend just gone (sufficiently insufficient sleep that at one point, barakta of this fair realm later told me she'd referred to me as "Duracell the Incoherent Bunny" the night before… and I didn't learn for two further nights after that…)
Haven't been on my bike for a week, with being out of town for a few days, and now too knackered to trust myself to remember how to use brakes. Fingers crossed I recover enough spoons to actually do it…

Not sure what my (imperial) alltime cycling Eddington Number would be (probably around 50), but I'm hoping, weather permitting, to nudge my running Eddington Number up to 15 this weekend.

My understanding of Eddingtoncompliant rides is that they are completed in a 24hour period. Thus, the Dunwich Dynamo, which starts about 8pm on Saturday, doesn't normally finish until boarding a train in Diss or some such, about 20 hours later. Ergo, all 149 miles count.
IMO, the explanation on Wikipedia is a simplified version. It says ‘days’ so the reader gets the jist of what the man meant.
In our world, it is ‘rides’, where a ride is where the average speed from start to finish is greater than 14.3 kmh. Refreshments, showers, changes of clothes and sleep can be taken within the ‘ride’ providing the average speed is not below 14.3 kmh when the ride finishes.
Using these guidelines, it is possible to achieve E 370 if 10 x 600km Randos are done per year for 40 years.
Now that’s a challenge for the teenagers here.

Success on E=21km!
1 more 17mi+ ride to reach E=17mi.
2 more 22km+ rides to reach E=22km.

The theory of Eddington.
If you start off riding 25 milers. Complete 25 of them and you’ve got an Eddington of 25.
To get to a 26 Eddington, you CAN’T use any of the 25 mile rides you’ve already done, so you’re committed to ride 26 more rides of 26 miles each.
To get to 27, you’re in the same predicament as you were when you finished your 25th ride of 25 miles and decided you want an Eddington of 26.
To get a really big Eddington number several decades in the future, build up distance as fast as you can, riding as far as you can and keep doing that.
Don’t mess about riding short rides over and over. Increase your distance up to 400 km randos and keep doing them until you have got 250 of them.
You are on a thirty five to forty year quest.
Then, you have some bragging rights and receive your club’s Lifetime Achievement award.

If you start off riding 25 milers. Complete 25 of them and you’ve got an Eddington of 25.
To get to a 26 Eddington, you CAN’T use any of the 25 mile rides you’ve already done, so you’re committed to ride 26 more rides of 26 miles each.
To get to 27, you’re in the same predicament as you were when you finished your 25th ride of 25 miles and decided you want an Eddington of 26.
No kidding :facepalm: but does anyone really ride like that?
My Eddington number is 39, but only two of those are 39.something miles. The others are
4x 100+ miles,
2x 80something miles,
2x 70something miles,
13x 60something miles,
5x 50something miles, and
11x 40something miles.

If anyone’s unsure how it works, the 30 mile daily commutes aren’t worth a jot after six weeks.
You have to put in a 50 miler once a week to get Eddington 50 after a year.
Then if you include a 100km Pop each month, it'll be 5 years to get Eddington 60.

I must confess I haven't sat down to work out my Eddington number, I'm just going off what VeloViewer is telling me. So if it's doing the maths wrong…

But that's not what he's suggesting. To use your numbers as an example... When you get to 102 miles, do you stop and get a taxi home because you don't want to do a ride which might count for an Eddington number of 103 before you get your E up to 102?

The behaviour I was confessing to (with tongue moderately in cheek) was
"To get a really big Eddington number several decades in the future, build up distance as fast as you can, riding as far as you can and keep doing that. Don’t mess about riding short rides over and over. Increase your distance up to 400 km randos and keep doing them until you have got 250 of them. You are on a thirty five to forty year quest."
I've set myself a target of E100+ and now keep riding to that as a minimum for a mediumtolong ride. However, I still ride audaxes of all lengths at least twice per month.

A 300 DIY at the start of the month plus PBP pushed my imperial Eddington number up to 142. The metric version is at 205 now.

Chapeau Ivo. At my rate of progress I should reach 142 by about 2025.

I would imagine that one Kurt Searvogel must be a prime candidate for a WREN.

His Eddington for this year alone should be near 200

Well now, with a bit of planning, Kurt might ride 200 steady 200s and the remaining days 190something, while Steve rides 220 long 220s with the remaining days 180somethings.

My Eddington obsession just ramped up a further notch as I gave in to the temptation to calculate all my annual Es as well as my overall E (overall E=84 with 2015 E=57). Is there an Eddington Anon meeting I could go to to break this habit?

It's held on Eddington Hill on the number of minutes equal to your imperial Eddington number after a blue moon. But not in leap years.

Ah, of course. Hence the Audax anthem "I'll find my thrill on Eddington Hill"

One of the fiendish things about Eddington numbers is how hard it is to plan when they go up. No Eddington Hill special for reaching 113, a couple of permanents in North Carolina this weekend meant that the number crept up to 113 without aiming to do so. 4 more rides are required for 114 so that will be next year some time.

I should work it out properly and maintain a spreadsheet. Veloviewer claims it's about 80 but this is too low as my Strava only goes back so far. In reality it's probably now around 120.

86 (it's probably a bit more but I know I've done 86 rides of >100 miles).
I'd like to ride 100 rides of >100 miles. That is an RRTY and a bit away, and maybe the post PBP challenge I'm looking for.
Realistically It would be very hard for me to get beyond 125 as most of my longer rides are 200km Audax rides (125130 miles typically).
There's a bit of a wilderness between 128 and 186 miles (when my few 300km Audax rides kick in) and I don't have any plans to start riding 186 * 300km Audaxes any time soon.
Anyone with a E=186 will be a bit of a legend (Steve Abraham must be running it close if he hasn't already done it)

In a pleasing bit of synchronicity when I complete my next 85+ mile ride (prob Saturday) each of my imperial, metric and annual Eddington numbers will go up by 1

I am looking for that magical day early next year when I ride my 500th 100km ride and so can claim E500 in furlongs. The current tally is 477.

Your personal spreadsheet might be a lot more accurate.

Your cycling Eddington number is 40.
According to your Strava data, you've cycled 40+ miles on 40 different days.
To reach an Eddington number of 45, you need 14 more rides of 45+ miles.
To reach an Eddington number of 50, you need 22 more rides of 50+ miles.
To reach an Eddington number of 60, you need 38 more rides of 60+ miles.
Yay!

You only have to update it when you do a ride which is over your Eddington number ;).

For the first year ever I have an annual Eddington number in the 60s (OK, exactly 60). Only two more rides to get it to 62, but then I pay the price for too often climbing off as soon as I hit 100k and will need a further 11 to get to 63.

I know the feeling. I took forever to get from 100 to 101 to 102. I am now in a period of slow progression until about 5 years time when I hit 125, after which forward progress will be glacial. Eddington was a hard taskmaster.
Interestingly enough Eddington is getting a bit of a renaissance as a physicist as well, based on my recent reading of an article in the Economist which was reappraising some of his ideas vis a vis Enstein.

An Eddingtontastic weekend: 2 x 200km rides meant increases in my Eddington no. (to 86), my metric Eddington (to 120) and my 2015 Eddington (to 63). Phew. Off for a liedown.

As opposed to his firstborn, En+1stein. :P

I'm so looking forward to be able to say that my Eddington number is 1, heck even 0.5 (Coming up to three years of the bike...)

To put these numbers in context I wonder if anyone apart from TG on this forum has a lifetime Eddington number >150 miles
Mine is 167 at the moment. I'd be very surprised if there aren't many others with higher than this, I've not been doing long distances for that long.

You've not been riding long distances for very long and have done 5 months' worth of rides of at least 167 miles?

You've not been riding long distances for very long and have done 5 months' worth of rides of at least 167 miles?
Yes. 34 of 600k+, 27 of 400k and 58 of 300k audaxes. That's 119 rides and the rest will be riding to and from 200k events mostly. That's in 10 years and many of those years have been quite lean years for long distance rides. What I was thinking is that those who haven't kept records could be surprised at how large their number could be.

600+km in a single day each time?

600+km in a single day each time?
Obviously not, but as I'm only counting 167 miles of them for this purpose, that's a strange thing to say. Are you implying that I don't understand what the Eddington number is? I generally record my 600s as 2 rides for each of the 2 days unless I go without sleep. Either way, they'd only add 1 to my Eddington number as I rarely need to do more than 150 miles on day 2. I've only done a handful of longer rides than this.
I hope this is the inquisition over, people must be getting bored reading this now.

Most folk wouldn't associate 'not that long' and a decade's worth of long rides.

Well done mikek.
Like me you don't necessarily split multi day audaxes into separate days. This means that my Enumber is understated as there will be about 20 days where I've exceeded my Enumber on 2nd, 3rd and occasionally 4th days of events, but not counted them, possibly because I've never bothered to check my distance at midnight. (and there aren't any counting rides at the moment where I did less than my Enumber on both days of a multi day event)
I've been doing long rides for slightly longer (12 years of 400k plus) but I don't get the opportunity to do as many long rides so mine will take a few more years to get to 125, and I'd need to get to about 30SR series to get an Enumber close to 167  so its probably more impressive than you think.

Averaging a 167+ mile ride roughly every 3 weeks for 10 years is both a very impressive achievement and  in my eyes at least  counts as being over a long period of time. Congratulations mikek.
I don't think there's a universally agreed answer to the "how to account for rides >24hr" problem. Personally, any ride that takes me less than 24 hours I count as a single day's riding regardless of whether or not it falls entirely within a calendar day. If a ride takes me more than 24 hrs I pro rate the distance by the number of hours ridden each side of midnight (which I suspect probably means my E is understated as I end up throwing some miles away uncounted if the ride was unevenly spread across the days).
Can't see myself ever getting to 167 but I'll hit three figures next year (all being well) and 125 isn't an unrealistic goal before old age overtakes me.

(cut&pasted from the TG thread)
Inspired by Jo's magnificent visualisation of the Eddington numbers I had a go at recreating it in Google Sheets for my data. Pretty straightforward to do. I used the .csv datadump from VeloViewer to get all my rides then used MS Access to total up the daily mileages.
See it here...
https://docs.google.com/spreadsheets/d/1c3WkBdf4T9TsZmM254QHBsaqt7n4AguOxeTgJPxCBk/edit?usp=sharing
Cool, thanks for that jochta. I've graphed my running Eddington number and concluded that, from my current 15, 17 is easily achievable within the next year, 19 within the following marathontraining cycle, and I may well never get to 20!
(just a small point  the inequality in column F needs changing to a ">=", rather than just ">". Otherwise, nothing shows up at the exciting moments when, so to speak, E=E+1 ;D)
(Edit to add: the same for the one in column E  I assume you want your 15.00 mile ride to contribute to E=15, and your 28.00 to E=28. I don't normally log warming up and cooling down from races, so Strava or Veloviewer would (should) record a 10m race as 10.00 miles. If it recorded it as 9.99, I would manually change it in the spreadsheet to 10!)

I added metric Eddington to my Google sheet and I'm E100 which is rather neat!
I'm one day of >=68miles to go up to E68. It's going to take me a while to get to E70 though as I need 15 days of >=70 miles...

According to veloviewer I am at Eddington of 90.
I know it is considerably under calculated. I have uploaded most multi day events as 1 long event, which it just counts as 1 ride no matter that it took 4 days (or whatever).
Even without going back to pre GPS days, I would reckon there's 1015 days that would work for me.
But, I will celebrate when I hit 100 even though I am most likely already there.
No doubt I will top out somewhere at 125 like most Audaxers.

I'm wondering how total mileage graphs with increasing Eddington number. I've just noticed that in my most recent 5000k of riding I have a metric Eddington number of 50, and somehow that seems about average (twice the minimum distance required). But is that anywhere near right on a larger sample or over a wider range?

The minimum distance you need to ride to achieve an Eddington number is the square of the Eddington number  so if you had only ridden 50 rides and they were all 50 miles long there would be no superfluous mileage  and you would get it done in 2500 miles. OF course, no one does this, and of course in this example, you would have no riders to count for E51 and above  if you wanted to get to 100 you'd need to do another 100 x 100 rides.
I've kept records on a spreadsheet of my rides over 20 years so you can see how things might progress  although with Audax and other things  over the last 5 years I have tended to do longer rides which helps advance the Eddington number.

The Eddington numbers are understated because I count multi day events (such as 600km Audaxes) as single rides, if I followed miles ridden in a day my E would be approximately 125 (but I've no way of measuring as I don't tend to care where I am and how far I've gone exactly at midnight on such events).
To give an idea of how hard it gets, I've ridden 80 x 100 mile rides since June 2011 to increase my Eddington number from 100 to 113. I need 4 x 114+ rides to get to E = 114 which will probably be April next year, and on current progress I will get to E = 125 by 2019 and E = 130 by 2025.

Eddington: 54 (miles), 71 (km)
What that means I have no idea! 8)

only got my head around this. so, let's say someone decides to achieve e=250, this would mean doing 250mile rides 250 times? assuming one ride takes one (long) day, and riding such a distance is better in warmer weather (aproct), and without going too crazy doing this twice a month  it would take almost 18 years?! doing srrty (as discussed in another thread) could reduce to 10 years.
i can see this challenge being appealing to a dedicated rider.

only got my head around this. so, let's say someone decides to achieve e=250, this would mean doing 250mile rides 250 times?
Exactly, and rides of 249 miles would have no value towards it.
Even Steve Abraham is likely to top out around 200 I expect, because he done loads of 200 milers, but they count for nought against an Eddington of 201.
I'd be surprised if Steve didn't end up with E=220 at some point (which is a fairly exclusive club I bet).
As Marcus implies E=125 is likely to be engraved on the gravestone of many Audaxers.
It's best not to learn about Eddington because it can lead to you thinking too far ahead.
For example, I have an E=87 (possibly more but I only track rides of 100 miles or more).
If I want an E=100 then I ride 100 miles 13 times HOWEVER.. If I rode 110 miles 24 times I'd have E=110. If I don't turn those first 13 rides into 110 miles then I get no closer to E=110.
So, if you want a big E number you'd better make up your mind at an early age and don't bother dicking about with rides under 250 miles.

But under more 'normal' circumstances the figures seem to show that when to I've been riding for some years, the square of your E number tends towards the distance you rode in the last year (or two of you're lucky, regardless of how many years you've been riding.

Interested in this :thumbsup:
Do you have any graphs / stats / other evidence to support? I typically average between 10,000 & 12,500 miles per year (variable work patterns mainly to blame) which suggests if you're right I'll never reach the gold star E=125 target but instead top out at around E=110.

With the high amount of audax riders there are no normal circumstances here ;)
My imperial Eddington is 143 while I typically ride around 10.000k (so 6250 miles) a year.

Your Eddington number will tend to get stuck around normal milestones. So mine progressed slowly through the 60s because that's the distance of my typical cycle club run. It raced through the 80s and 90s but made very slow progress from 100 to 103 as a century is a target distance and a lot of my rides tend to be of that distance (including my occasional commutes to London). Like many Audax riders it will then get stuck in the high 120s due to the number of 200km events  although I am luckier than most.
However, beyond about 130, you are going to be a seasoned Audaxer, one who regularly gets 5000km+ of events a year, a supertourist, or a record breaker, or someone who has decided to dedicate their life to an obscure record and set out (as a few posts above have mentioned) to specificaly reach an eNumber.
I view mine as a mathematical curiosity that defies any attempt to deliberately influence its outcome, but is simply a consequence of me doing what I like doing which is riding long distances on a bicycle. Freed from work and family constraints it would probably go up much quicker, but I rather value both my job and family so such things are idle fantasy.

Just picked up this additional challenge
Been commuting regularly since Apr 09 and building towards longer distances as domestic circumstances permit.
Eddington= 57 (=age)
Got 3x 200 to complete for my RTTY so a slight increase may be possible.

Out of curiosity I searched on Wikipedia https://en.wikipedia.org/wiki/E_number#E100.E2.80.93E199_.28colours.29
to see what my Enumber (food additives) my Eddington Number coincided with. Sadly there isn't anything until I get to E120  Cochineal. However you could have the equivalent of a judo belt system as I discovered they are based on colours:
E100  109 Yellow
E110  119 Orange
E120  129 Red
E130  139 Blue
E140  149 Green
E150  159 Brown/Black
E160  199 Gold
Tarzan and Teethgrinder, who are in the E200+ range unfortunately have entered the world of preservatives.

My running Eddington Number is 15. If I went out for a 32 mile run (as I attempted over Christmas but cut it short at 18 because I was feeling really ropey), could that legitimately count twice towards 16? Would I have to stop running at 16 miles, stand about for a couple of seconds, then start running again? My wife says that she would only count it once...

Nope, I wouldn't count it twice. Sorry. It's the number of days you've done n miles, so it'd count as 32. But do it another 31 times... ;)

39, but my data only goes back as far as 2013

I think it would go up if I could add by older rides to it. Must see if I can get the numbers out of BikeJournal.

From 2007 to the end of 2015, my metric Eddington number is
112 118 and imperial is 89 93. :thumbsup:
[edited to split my 600km + audaxes into individual days.]

;D There is not the faintest chance that I will ever achieve an Eddington number greater than 26.

It's a start, I suppose...

Well, I really wrote it for fun, I'd wanted to play with Eddington numbers since I first heard of it. I haven't spent much time on Veloviewer, as I haven't paid for it. My Eddington number on there, from 25 rides in 2008, when I was working 3km from home, is apparently 4.
So the differences i can see are
 It's free
 It works with Endomondo and MyCyclingLog as well as Strava
 It can split overnight rides

Well, I've paid for veloviewer for the other things it offers as well, don't use endomondo or mycyclinglog and don't do any overnight rides that I'd want to split… so I'll probably pass, but hope you get the feedback you want off people who'll find it more useful :thumbsup:

For the old hands it still has the disadvantage that the preGPS rides aren't considered.

Well, it does work with MyCyclingLog, which doesn't require GPS. If your rides are recorded on a spreadsheet (or a text file), it's very easy to upload that to MCL.
But if your rides are recorded on paper, I don't think there is a technological solution for you :(

Strava doesn't require GPS

But does the data spat out by the API (and therefore available to J's tool) include the manually entered rides? I vaguely remember some Strava API tools not including them in their output.

It works fine. It doesn't tell you when it's done (despite saying it will) but it usually only takes a minute or two. Be careful to get the columns and date format right, as it will work even if they are wrong, just makes a mess of your data, and it's a real pain if it's wrong to delete it all. I used the wrong date format, and it put a lot of my rides into the future.

No, manual rides work fine. As the strava API no longer gives GPS data, there is no difference between manual and recorded rides as far as the API is concerned.

Thanks :thumbsup:

E = 500f
500th 100km = 500 furlong ride today. :smug:

Now I`ve gone right back thro records I have am on E =117

Mine is three, not bad after three and a half off the bike :)

My 200km DIY on Good Friday took me to 89, and still on target for E = 100 by the end of the year. There may not be a badge, but I shall sure as hell be getting myself a tshirt.

Hit 100 today. 10 x 101 milers needed for 101, 47 x 105s for 105. I've only done one double ton, don't see myself doing 199 more.....!

You have my sympathy. It took me three years to move from E100 to E103 and then just two to get from E103 to E113.

Is that using my page? Coincidently I updated last week (following the complaint of another 3digit rider) so it tells you how many rides for the next 3 distances as well as the impossible remote goals. (eg 101, 102, 103, then 105)

Today's ride of 81.65 miles slots in at no. 38 in my alltime list. I have now completed 69 rides in excess of 71 miles.

Is that all thing1? It seems very low to me? Or just since _{STRAVA} records began?
;D Yes I realized I used to Audax without GPS, and there's probably a few touring days over 80miles that won't be on there either. Would be interesting to xref the brevet cards. I don't think I'm over 100 though.
I noticed my enumber had hit 101 today. So I finally sat down with the box of brevet cards from 20052011 and made strava manual ride entries for all the 200km+ rides.
With those included... E = 118. :thumbsup:
I only need 3 more 200km to hit 120, but it's going to take a very long time to move the needle much beyond that.
EDIT  an interesting observation is RAAM (the race itself, not the training) is not doing diddly squat for my E number: we averaged 115 miles per tandem per day...

Put all of my rides into a database and now I can work it out properly (I think).

Simple little stored function called enumber does all of the work for me.
Anyway, my Eddington number at the moment is 63 and I need another 3 rides of 64 or more miles to increase it.

Have you seen this though http://mcgalliard.org/eddington/
makes all working out done for you,
and I`m now 119 btw :thumbsup:

Mine is ten, need two rides more, above 11 to get to 11. Then it will become harder because my max distance atm is about 18 and I don't think I can keep at that for too many days in a row.

Using jefmcg's excellent web page, I sorted out the multi day stuff and have got to 115
But it will be hard work to get much more! EAch step will take multiple rides.
Good stuff though!

:thumbsup: A very impressive E no., and within sight of the Audax gold standard of 125 :thumbsup:
Currently on 91 myself, with just 12 rides to get me to 100 so will hit that later this year. However, getting from 100 to 101 is going to take me pretty much an entire extra year (though harbouring optimistic hope that I might hit 101 whilst on LEL).
My other cunning plan is that my E=100 ride will be from home in S London out to Eddington Hill nr. Hungerford and back.

With last weekends ride, it took my number to 109.
Your imperial Eddington Number is 109.
You need to do 3 ride(s) of at least 110 to increase it to 110.
You need to do 13 ride(s) of at least 111 to increase it to 111.
You need to do 22 ride(s) of at least 112 to increase it to 112.
You need to do 44 ride(s) of at least 115 to increase it to 115.
You need to do 63 ride(s) of at least 120 to increase it to 120
Starting to get much harder now.

It really is a cruel measure:
You need to do 2 ride(s) of at least 116 to increase it to 116.
You need to do 7 ride(s) of at least 117 to increase it to 117.
You need to do 8 ride(s) of at least 118 to increase it to 118.
You need to do 12 ride(s) of at least 120 to increase it to 120.

As of last Sunday I have completed 100 rides* of 100 miles.
* simple** definition, where, for example, LEL = 1 ride of 100 miles plus.
** though I'm struggling to define it other than by the frinstance.

Another notch on the old Eddington bedpost
Now at 110.
Now it get's a bit difficult..

Mine is now 11 :) Two more rides above 12 to get to 12, slowly does it.

Last weekend finally got me to E=120.
Big bloody way still to go for 125 though
You need 3 more days (of 122 miles or more) to achieve an Eddington number of 122
You need 6 more days (of 123 miles or more) to achieve an Eddington number of 123
You need 9 more days (of 124 miles or more) to achieve an Eddington number of 124
You need 21 more days (of 125 miles or more) to achieve an Eddington number of 125

The Dun Run on Sat/Sun took my Eddington number to 71. My 71st ride was 71.09 miles.
Such is the paucity of rides in the next chunk, it will take me only 9 >75 mile rides to push my E number to 75.

+1 on that too, I reached E=120 after a w/e 123 km ride but as you say a hell of a lot to ride to E=125 ::)

My (incomplete) attempt at the "Old Roads and Drove Roads" audax on Saturday was enough to bring my Eddington number up to 50.
It will be slow progress passing it up from here, though, as I have a lot of 50ish mile days of recreational riding with friends on my record; 13 rides required for E=55, and 26 rides required for E=60....

It's been pointed out to me that Veloviewer shows your Eddington number automatically :thumbsup:
(https://cf.veloviewer.com/blog/2016+Infographic.jpg)
Unfortunately, I don't do Strava :(
And even if I did, noone connected Huret Multitos (http://www.sheldonbrown.com/cyclecomputeraccuracy.html) to Strava, and so many of my early rides would be missing.

If I were in your position, and had ridden 122 miles, I would try damn hard to find the extra 3!

In the last month have managed to tick over E115  E116, but also now have E= 504f (furlongs).
I need another 19 rides of 125 miles or more to reach E = 125, although pedantically, 124.3 miles is just over 200km, so E = 124 will do that and I only need 17 rides of 124 miles or more. At current rate of progress E = 125 will be another three years. However, if it's any consolation, the furlong number is also difficult to shift. To get a 9 point improvement in the furlong Eddington I will need another 38 rides of 63.9 miles (513 furlongs or more).
However, did have the satisfaction of passing Jack Hobbs record of 197 centuries in first class cricket with my 198th lifetime century cycle ride last week. I've now decided to keep up with snooker players scoring centuries on the professional circuit, but with Ronnie O'Sullivan in the 700s and still potting I don't think I will ahead on that list.
(reluctant accountant  has lifelong fascination with numbers and an aversion to process)

127 :D
I don't think I'll go much higher than that  16 more to get to 130, 76 more to get to 150...

Six months and five days after hitting E=100 I've finally reached E=101, all the time cursing every ride in the past when I'd climbed off the bike the moment I passed 100 miles.
Next major target now E=125, all being well about two years away.

Mine is 32, mostly achieved this year. But a lot of my riding is done off road ;)

Nudged up to 117 with the Brimstone

The Maastricht 400 of last weekend pushed my imperial Eddington to 150.

Hungerford Hurrah takes me to the imperial century.

^ :thumbsup:
Has anyone got a good (or even rough) estimate of how many folks there are with an Eddington of 100 or above?
Are centurions part of a tiny club, or twoapenny?
And if 100 doesn't mark the boundary between "more common than you might think" and "actually quite rare", what does? 125? 150?

A lot of longterm Audaxers will have Eddington numbers around 125. Getting much above that is pretty rare.

A lot of longterm Audaxers will have Eddington numbers around 125. Getting much above that is pretty rare.
But still quite reasonably available among long term Audaxers. An Eddington of 200 puts you way ahead of the crowd.

Not too many folk have ridden 200 days of 300+km brevets.

Not too many folk have ridden 200 days of 300+km brevets.
Indeed, a shedload of 300k audaxes isn't even enough for an Eddington of 200.
An Eddington of 150 is quite well possible for audaxers who don't have a car so tend to ride to their events, either from home or from another sleeping spot.

New Eddington number reached. 113.

The Dun Run on Sat/Sun took my Eddington number to 71. My 71st ride was 71.09 miles.
Such is the paucity of rides in the next chunk, it will take me only 9 >75 mile rides to push my E number to 75.
Something seems to have gone wrong with my recording. I have just put this year's Dun Run in and the spreadsheet reckons that this year's ride pushes me to 71 miles. Shome mishtake, shurely...
Edit: yes, I did make a mistake. I didn't do the sort properly on the spreadsheet and my 72nd ride is indeed 71.09 miles.

My running Eddington number has nudged its way to 19.

My running Eddington number has nudged its way to 19.
Should be able to edge mine up to 15 with this winter's marathon training (assuming my foot gets better and I can actually start running again).
(The long runs in my training plan are 14, 15, 15, 18 and 22 miles but if I ever get my weight down and get back to proper fitness I intend to keep it going after the marathon rather than falling back to apathy and doing nothing long for 8 months before building up again...)
Having recently signed up to VV and uploaded the history I have I can see my cycling EN is 53 (miles) or 60 (km). (I have 36 rides of 124 miles or more, so a long way to go in terms of the 'long standing Audaxer' standard although I personally count multiday rides as a single ride...)

Finally got to E = 119. It should move a bit faster now as there aren’t many rides logged in the 190  200km range

Chapeau :thumbsup:
I’m on 118 with fairly small increments up to 130, but then the cliffface gets seriously steep.

The Heart of England brought the Eddington number up to 120.
E120 is Carmine, or Cochineal, the red dye made from crushed insect bodies.

125! On track for 126 this year (3 more rides needed, which are already in the calendar)
Also: everyone nominate yacf as your club for the the Eddington Number club challenge, here: https://swinny.net/Strava/4968TheEddingtonLeaderboardforClubs
We should be able to own that.

Only if you are on Strava... I suppose I could add all of my rides manually but that would (a) be anal even for me and (b) be regarded as totally suspicious and fraudulent by everyone who hadn't actually ridden all the miles.

Finally made the century :thumbsup:

Made it to the magical 125 :thumbsup:
Boy does it get harder from here though  37 to 130, 82 to 140 and 105 to 150. I can just about see myself getting to 130 within a couple of years, but I suspect my final Eddington will be in the low 130s.

Does anyone else calculate their Eddington in Metric?
I've only got records of my rides from last Autumn, so my number is low, but growing steadily.

Imperial, metric, and furlongs (handily there are 8 furlongs to a kilometre). But any reasonable unit of measure will do, as I have all my long rides in an excel spreadsheet it was a matter of a minute to discover that my Eddington number is 109 (Nautical Miles) and 57 (English Leagues) or even 35 Norweigan mils.

E121 in miles, which is also Citrus Red 2, which can be used in the USA to color the skin of oranges, although it is suspected to be a carcinogen. So take care when using orange zest for your chocolate and orange cake that you don't use American oranges.

...(handily there are 8 furlongs to a kilometre)...
Ahem.
Veloviewer does it for me, it gives me:
Eddington: 53 ml, 62 km, 109 min, 920 m (46)
(The 920 m (46) is climbing, which is done in chunks of 20m. So I've done 46 rides with at least 46x20m climbing.)

My running Eddington is now 20. :thumbsup: :smug: ;D

Managed 125 miles in the murk and the wet on Saturday, which brings my imperial Enumber up to 122.
E122 (Azorubine) is red food colouring used in the EU (but not the US) in some cheeses, dried fruit, and alcoholic beverages.
Cheers! Or dried apricots?

Definitely worth raising a glass to :thumbsup:

Slowly creeping up. Am up to 52km now. Doing 100+km for 10 days in a row certainly helped. Have a suspicion it's going to stall at about 200km tho.

I expect my metric Eddington to get stuck at about 210, as it's rare for a 200k Audax to finish spot on the distance.

Not checked for a couple of years, so pleased to see that I've hit E=101 :)
I need 2 rides >102miles to get there
I need 27 rides >120miles to get there
after that it goes downhill quickly :)

For the older folk (and those who only started counting recently) what's your agerelated Eddington number?
That's n rides of n miles/km after the age of n years. I'm currently on 58 metric and hoping to get over sixty but there will be a lot of longer rides I'll be losing.

70 (Imperial) or so (on the evidence of 81 imperial centuries in the 6 years since age 70).

Reached E=515f today, 515 rides of 515 furlongs or more. A joyous statistic. E515 is potassium sulphate used as an acidity regulator.

I'm an accountant. I have a spreadsheet. :facepalm: It also calculates it in metric, imperial, and nautical miles (110). Sadly the nautical one is trapped in the quagmire of 200km and a bit rides so it's going to need 24 more to get up to 115. At current rate of progress that's about 4 years. The furlong one is giving me more encouragement as that tends to go up more frequently.
But Eddington is a cruel task master. To get E515f to E600f, which is probably about as high as it will get, requires a further 262 rides of 600f (75 miles, 120km) so I'm only about 56% of the way there.

With Le Tour de Neuf Chevaux Blanc (highly recommended by the way) yesterday, imperial Eddington number has reached E = 123.
E123 Amaranth is a dye, commonly used in food. Unusually it is banned in the US as a suspected carcinogen, but is still authorised for use in the UK where, among other things, it is used to give Glace Cherries their distinctive colour. Had I not bought Factor 50 in Boots at the Marlborough control point as proof of passage my skin may well also have resembled Amaranth. As it is I'm walking around today with a tan no one would believe was earned in Wiltshire in March. A student of irony may wonder at the number of Glace Cherries used for cake sales on behalf of the Macmillan Cancer Trust.

The Auld Alliance has taken my Eddington Number to 124
E124 is another synthetic azodye used to colour foodstuffs red, with lots of investigation (inconclusive) into any negative health effects, it has many names, of which the most common is Ponceau 4R. When I Googled E124 most of the sites were French, suggesting that they have had a stronger debate about it than other nations.
It also brought my Eddington number in Nautical Miles to 111, which is often referred to as Nelson, after Admiral Nelson, which seems rather appropriate.

My Eddington number in furlongs is now 517. E517 is Ammonium Sulfate, which is used as an acidity regulator in flour and bread.

With the aid of my firm's charity ride around all their offices and being environmentally friendly by riding to the start and back from the finish of my two allocated days, put in back long rides yesterday and today (125 miles and 152 miles respectively), which had the effect of getting my Eddington number up to 125, where it will stick for about a year, courtesy of all those minimum distance Audax events.
E125 is another azo food dye, no longer permitted either in the US or Europe

Furlong Eddington number = 518
E518 is Magnesium Sulphate, more commonly known as Epsom Salts, which very appropriately can be added to bath water to relax tired muscles.

After being stuck on 129 for what felt like forever have finally made it to 130.
From here to 133 not too steep, but every increment after that looks pretty daunting.

To be honest I'm only keen to hit 84 (currently at 82) after that it'll increase steadily as I do more 200s and then pretty much stop at around 125.

E=522f  its crept up a little bit over the winter  E522 is potassium alum, which I use as a natural underarm deodorant  under the Salt of the Earth brand  not sure that means I've been particularly neutrally scented over the last few months. Am 1 ride of E=523f, hopefully Sunday, as I'm not getting rides in which are long enough to work on any of the other Enumbers.

Today's effort took my Eddington number in furlongs up to 524. E524 is Sodium Hydroxide also known as Caustic Soda or Lye. Nasty stuff but it is used to glaze pretzels and as the preservative in stockfish (Norwegian disk Lutefisk uses fish cured with lye).

Snuck my furlong Eddington number up to 526  that's 526 rides of 526 furlongs (65.8 miles) or more. The qualifying ride was Basingstoke down to the top of the New Forest, before heading up to Salisbury Plain via Fovant and Dinton.
E526 is Calcium Hydroxide, also known as slaked lime, with a vast number of applications from building, water treatment to food, including pickling cucumbers.
My imperial Eddington number is stuck on 125, for obvious Audax reasons.
