I think this will be too much vertical gain for my L knee but if next week's skiing does not confirm my fears I will enter or at least turn up for the finish. I may have a new bike with a triple by then and so would have an opportunity to road test.
PS I think I have successfully duplicated the route on ridewithGPS.com together with a turns list and a scary elevation chart - saved as Cheam&Morden hilly 50 km
