For some reason, I've decided to have a go at a half-iron man distance triathlon (swimming 1900m, cycling 82k and then running 20k)....raising money for charity will help me cross the line.

The money is being raised for Tri for Life, a charity which will distribute the proceeds to a variety of other charities such as Rays of Sunshine, Teenage Cancer Trust, World Jewish Relief, MTV Staying Alive Foundation and Great Ormond Street Hospital. Tri for Life is holding its own mini distance triathlon if you fancy having a go (400m swim, 20k cycle and 5k run) - see www.triforlife.co.uk

I don't have a target in terms of a time (although around six hours would be nice), please help me make the pain worthwhile...

Donating through Justgiving is quick, easy and totally secure. It’s also the most efficient way to sponsor me: Tri For Life gets your money faster and, if you’re a UK taxpayer, Justgiving makes sure 25% in Gift Aid, plus a 3% supplement, are added to your donation.

So please sponsor me now!
