I too am up for fatboyralph's suggestion. Don't really like the idea of 30,000 other cyclists to be honest. I will attempt it on my 48x17. Hoping that going up Highate Hill every night with a heavy bag will stand me in good stead.

BMMF, will you be doing any more of the Saturday morning hill runs again. I still can't believe how quick you got up some of those hills. Especially Muswell Hill
