+1114.8 vs Godwin line
+920.9 vs Searvogel line
-395.9 vs Amanda after 70 days
-1095.4 vs projected Coker line


Is the "projected Coker line" just a straight line i.e. shows the average required to do every day to match Coker's projected total?

Spot on. 
Her anticipated total (only anticipated for a few more hours) / 365 * the number of days Steve has ridden.

Week 11:

Those who worry about sleep issues take note this week, if anything is going to show up surely this (week 12) will be the week.  Last week Steve pushed every irregular sleep boundary.  He posted 13 rides which means he was active at midnight 6 out of 7 days.   From lunchtime on Thusday he was active for 36.5 hours straight of which he was moving for 30.75 hours.  He did allow himself rest of 14 hours before and 12 hours after that marathon.  The result is his second highest total for the year, 2566.9 miles or 227.86 mpd average.  Week 1 was highest naturally.

His routes were interesting, for a change he did keep to the flatlands.  8813 mtrs climbed is his lowest weekly total by 500mtrs and only his second week under 10,000.  Steve didn't use this to gain speed, his average for the week was 26.15 but there's no automatic correlation as Steve consciously controls his speed.  We do have enough data though to see if there is an unconscious relationship between speed and meters climbed. 
This is a spread of his rides so far, speed in kmh on the horizontal and meters climbed vertical:

Lopsided in the expected direction?  Add a trend line:

Yep, a clear trend to flatter routes = more speed.  That outlier looks like it is skewing things though, lets remove that:

The outlier (3rd April, his east coast route to Ferrybridge with a reasonable tailwind) was skewing the result but the trend is certainly there.

Does anyone know if the kJ work done figure on Strava comes from his power meter or a guesstimate from the route?

1270.2 ahead of the Godwin line.
1056.9 ahead of the Searvogel line.
1157.5 behind the Coker line.

Weeks are slippery things.  If take day 1 as day 1, and week 12 as Sat 13-Fri 19 May, you do indeed get that.  But if you align with a Monday-Sunday week, skipping the first two days (which I think Steve has mentioned in his videos, and which aligns to Strava weekly totals which makes for easy cross-checking) the week from 15-21 May was actually his lowest since the start, at only 215 mpd.

Does anyone know if the kJ work done figure on Strava comes from his power meter or a guesstimate from the route?
I'm fairly certain that the avg Watts comes from his power meter.  Some rides he uploads from GPX files, and the watts are missing, some rides come from his Garmin 520 and the avg Watts are present.  Not sure about the kj figure, I've never really looked at it.

From Strava

Quote
​
Total Work, expressed in kilojoules (kJ), is simply the sum of the watts generated during your ride. There is a close 1–to–1 ratio with Total Work and Calories expended during a ride.
​

Since he's running a power meter, the kJ figure will be from that.  Remember, energy = power * time.

You know that, I know that.  But Strava has a tendency to make things up so you always need to be careful about the provenance of the data.

My last quote was from a ride on which I had a power meter.  Here's the equivalent text from a ride in which I didn't have a power meter.

You'll note that if you have a PM then Strava gives 'Power', whereas if you don't have one, it gives 'Est Power'.

Quote
Energy Output measures the amount of work you've done during a ride, expressed in kilojoules (KJ). It is a factor of how much you're pedaling, how fast you're pedaling and how much force you're exerting on the pedals (measured in W). Power output is most accurately taken from a power meter, but if you don't have a power meter we give a rough approximation through our power estimator.

Funny what pops out of the numbers when you look and I missed Steve saying that.  It's surprising that which weekend forms part of the week makes such a significant difference.  The weekend before was certainly big but the weekend after didn't seem that small.  Using the strict day number week he has 3 lower than 215mpd.

Thanks all for the quotes on strava power.  I may go back over the rides and add that to my spreadsheet then see what relationship there is with climb and speed.  Don't anyone hold their breath though.

Drop me a PM if you want the backlog of power readings from Strava for each ride in spreadsheet form and I'll email you a csv.  Will make going back over your rides easier.

I've idly done a bit of analysis relating speed and power and come up with the earth shattering conclusion that when Steve puts in more power he tends to go faster, but not always.  I think there may be a PhD in it.  Steve was quite clearly (or clearly-ish)  gradually increasing his power input up to about day 60 or thereabouts, and it's levelled off a bit since.  Speed crept up commensurately.

The headache that the power data provides is that not every ride has power data.  Sometimes you get days with two rides, one of which has power data, and one which doesn't.  It all gets a bit messy.

Yes, well done Steve, the weather's turning getting better so just enjoy being out on the bike, you deserve it after all that wind and rain.

Week 12:

Fairly normal week for Steve.  He's kept to the fens a fair bit and recorded a third week under 10,000m climbed (9050m).  He was out past midnight twice and neither benefited him in mileage but that's not why he does it I'm sure.  He rode a long Saturday returning home at 6am Sun then back out for a short one, 411.7 miles.  Thursday he set out at 09:52 and was moving 29 of the following 36 hours for 441.7 miles.  Both those are below his year to date daily average of 221.7.  Thursday night was particularly still which is far more likely the reason he was out.
Of the other three days he was out & back before midnight two were above his year to date average.

216.76 mpd average for the week
1347.9 ahead vs Tommy
1115.3 ahead vs Kurt
1300.5 behind vs Amanda

I overtook Steve today while heading to Mother in law's house, in the car. He looked happy enough bombing up the A10.  :thumbsup:

Week 13:
A new record low on meters climbed (8794), high since week 1 on daily average (231.15)

Week 14:
A handful short of a new record high on meters climbed (12559) and not great on daily average (215.61)

Both of these are I'm sure down to the wind.  It was pretty mild at the end of May but June has so far been exceedingly vent lateral.

+1596 vs Tommy
+1324 vs Kurt
-1494 vs Amanda

Saw Steve this morning in MK just after the start of today's ride. Gave a friendly toot and a wave from the car and he smiled and waved back. He was looking good  :)

Go Steve.

Steve appears to have taken a 2 hour nap in an Audax hotel in Clophill early yesterday morning. After that he went home arriving about 07:50 and stayed there all day.  Any word on book face etc? Planned or unplanned basically? It was day 100.

Whatever was up (if anything) isn't today.  According to the Ivanoscope he's been moving at 29kph since 09:00.
