AAA points have ‘changed value’ several times since the scheme was created. It isn’t really possible to compare AAA points totals that are widely separated in time.

I'm aware of the 2009 change which was to award AAA based on metres climbed irrespective of distance (subject to a threshold for each distance) but that rule hasn't changed since in AUK AFAIK. What has changed is that previously eligible rides (calendar perm and DIY) have been downgraded but not uniformly across the UK. The South East with our many shorter sharper hills with lower maximum altitudes appear to have suffered more as a result.

Previous to 2009, the AAA points system was revised once or twice. Changes to perm eligibility altered how many AAA points could be accumulated in a season too. All of those changes meant that AAA totals before and after each of the changes couldn’t be directly compared.

I figure that alterations in how altitude is measured (e.g. contour counting vs. GPS records) similarly means that direct comparisons before and after those sorts of transitions aren’t really possible. It is common knowledge that different GPS devices or altered settings or using various phones to record GPS tracks can give quite different elevation gains round the same route.

Having played with the Nasa 90m dem that gives Googles laughable elevation data, and tried out a few comparisons where I know rwgps' data is duff compared to Strava's crowd sourced barometric data (south loch tay road} I've just realized I've never thought to put a route using it through the tool to see what it's data makes of it.

I'm curious as to the nature of the os data, is it automated contour counting, a 3d model of the osgb grid or something else?

I can quite comfortably get AAA qualifying routes in "flat" Fife, rarely above 100 and mostly high single digit to mid-teen gradients.
Any imbalance from a consistent quality model would suggest previous methods were imbalanced.

Surrey Secrets reinstated on the basis that its AAA have been honoured by the new system  :)

Thanks for the clarifications, Martin. Surrey Secrets also comes in at 1870m for 1.75AAA as per Pete's variation.

Note that if you have any ride validated as a mandatory DIY and for whatever reason your track doesn't get awarded equivalent AAA then I am prepared to take the figures from the intended route as submitted if you flag this up to me.

Thanks Ivan; I have directed SS entries to Manotea (as regional DIY man) but hopefully any (unlikely) problems will come to you eventually  :)

Thanks for the update Martin. And thanks for the info Ivan.

I will look forward to riding it again ............ although some perusing the OS map has now convinced me that with a few more route tweaks I may be able to squeeze an extra couple of hundred metres out of it.....  :)

the route was devised by cover girl formerly OTP who made many variations / extensions around it including one which was worth 3AAA! I wanted to make it a calendar event with the Secrets being just that, secret controls, but it was a logistical nightmare. I rode it many times when I lived near there and never needed a triple chainset unlike Tour of the Hills

Be sure to look out for the Space Station en route! and the cheese straws in Peaslake village shop  :P just before the aptly named Walking Bottom

I did spot the space laboratory, which I definitely wasn't expecting in a leafy surrey lane!

All those Surrey Secrets variations sound intriguing. Do they still exist anywhere (e.g. rwgps), or are they now lost in the mists of time?
