Right, so I'm going to run over 13 miles in order to raise money for People and Planet, who campaign on climate change, human rights and world poverty. All pretty good causes, I would say. So if you can dig into your pockets, or down the back of the sofa to find a couple of quid to sponsor me with that would be amazing. I need to raise at least £250, so please sponsor me now!

Donating through Justgiving is quick, easy and totally secure. It’s also the most efficient way to sponsor me: People & Planet Trust 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.
