Ride London 100

I did 87.5 miles, being the course south of the Thames - starting/finishing at Putney bridge - in 5 1/2 hrs, ave speed 15.7mph

My advise is to get round and do the course to find out for yourself - I was a bit taken aback by how hard it is - I found the run from East Clandon to Abinger, a lot harder than Box Hill, as it has three climbs in close succession and seems to go on far longer.

The upside is that as soon as you've done it, you'll accept it is very doable.

Good work sir, and a lovely day for it. Did you Strava the route? I was going to scout it out sometime in May too.
