Earlier this year I committed with my Channel 4 co-presenter Krishnan Guru-Murthy to cycle from C4 HQ to the Eiffel Tower in 24 hours in aid of the Duchenne Children's Trust. You can find all the details on www.bike4good.com but sadly I have just had to pull out of the ride for reasons of a boring domestic nature. So as penance I have agreed to do what all cyclists do to go faster - have myself waxed. My target is £10k per leg. If you get to £25K I'll do the whole body. It will hurt - probably more than doing the ride. That's the idea. So go on - you know you want to.
