Im aiming to do this.
A friend of mine is doing it for the BHF. Another friend of mine is also doing it, although just for fun - he's a photographer with a cycling magazine and a cycling nut. He's also very fit. Last weekend he completed the 85 miles Paris-Roubaix. Starting this weekend, he's doing a 12 day Lands End -John O'Groats tour. Needless to say, 54 miles should be a doddle to him.
Anyway, they both asked if I wanted to join them for the L2B. I said yes.
Considering that a month ago was the first time I'd sat on a bike since I was about 15, and the fact I've put a lot of weight on in the last year, I've definitely got a lot of training ahead of me to catch up to their level. Agreeing to join them on the ride was more of a motivation to exercise for me, something to galvanise me, and something I think would feel amazing to achieve. So my friend has leant me a 10 speed Raleigh and we've been heading out each weekend on long rides in training.
So far, I don't think I'm doing too badly. Two weeks ago, after getting the bike off my friend, I went out after work, intending only really to ride around the block - I ended up doing 9.5 miles. The following Saturday, we went out and did 22 miles, got home and both felt good, like we could carry on.
Tonight, I went out again, and did nearly 11 miles with no problem. Hopefully if I can keep up a routine of doing 10 miles every few evenings after work followed by long rides at the weekend, the weight should come down, my endurance should rise and I'll be ready to tackle the L2B.
At first, I was dubious, but after reading about the route, I'm in high spirits, and actually looking forward to the challenge. The biggest problem I have at the moment is getting saddle sore; just need to find some padded shorts...
