It's probably been discussed to death on Catford HC threads. [smug]I've been the fastest up on fixed 3 times [/smug] - 2m04, most recently (in 46x22 / 55inch). Only gone under 2 minutes once in training. We went up it recently, sort of by accident, on a Ant's Kentish Rollapaluza CC clubride. Well, me and hippy rode up, the rest walked, but no shame in that, as it's fucking ridiculously steep, although the short section of 20% between the two 25% stretches is a bit of a breather :O I still think Chalkpit is worse, from memory. The severity of climbs is about more than steepness alone.
Yeah, me and bmmf, regular little mountain goats we are..
