In April I will once again be running through the centre of London. And once again, I'm going to be raising money for Shelter.

Shelter helps the homeless, and those in bad housing situations. Affordable housing is hard to come by in London, so I hope that you'll help me to help many of the people I'll be running past in April.

And if not ... well, donate to support me wearing something silly in front of thousands of spectators, and broadcast on television. Me in fancy dress - that's got to be worth your while.
