The photograph to the left was taken at my recent triathlon training camp in the himalayan foothills. This time spent pushing my body to the limit while at altitude has proved invaluable and I am now much better at holding my stomach in.

I've got a dodgy knee and I'm carrying 27 stones of excess baggage but I'm going to swim 1km, run 10km and cycle 80km for charity, so the least you can do is join my celebrity friends and sponsor this valiant effort, after all it is for the kids (and the adults).

And if I don't make it, remember, I love you all.

Donating through this site is simple, fast and totally secure. It is also the most efficient way to sponsor me: Aplastic Anaemia Trust will receive your money faster and, if you are a UK taxpayer, an extra 28% in tax will be added to your gift at no cost to you.

So please sponsor me now!

Many thanks for your support (I'll be wearing it on the day).
