Good to read that the AAA Milne lives up to the name. I will be pulling together the routesheet and submitting the ride to "the powers that be" in the next month or so. Should be available generally from the New Year.
The 1,900m climb figure is slightly more than I would expect. I'll do a contour count as part of the submission, as I don't personally trust the climb figures that come out of GPS units, which appear to overstate climbing in the South East by 10% or so.
Now that one is out of my system, I can turn to plotting my 200km and 300km permanents. The outlines are there (respectively at least 3 and 4.5AAA, possibly more). I've a choice of routes for each (variations on a theme) so now just need to decide whether to be twisted or evil. I want the 300 to be the definitive grimpeur event in the South East, which to me means taking in half a dozen of the "classic" climbs of the area (White Lane, Leith Hill, Box Hill, Yorks Hill/Ide Hill, the Wall, White Down, Toys Hill). I am so close to getting these into a nice route, albeit currently at 315km and goes down rather than up the Wall. So, so, tantalisingly close. I'm genuinely looking forward to making it happen.
