I have never asked you to sponsor me before, and very likely will never do anything like this again. I will never run a marathon, ever. Even 10k: it isn't going to happen, ever. Triathlon: no! Simply never going to happen. For those of you that haven't seen me in a while, I am no thinner than how you remember me....

But in four weeks I will attempt to cycle more than 260 miles from London to Paris in 24 hours to help save the lives of thousands of boys with Duchenne Muscular Dystrophy (DMD).

So please dig into your pockets and help save lives and defeat the biggest genetic killer of teenagers and young men in Britain. Oh yeah, Google will match every pound you give, with another pound :-)
