I love running and the environment, so I thought I'd try the challenge of running the London marathon in under three hours for WWF. 

I will be extremely grateful if you can donate even the smallest amount for WWF's vital wildlife and climate work. The world's environment would be a poorer place without it.

You can donate by SMS too:
