I've run a marathon (or two) and now I want a new challenge. So I am going to walk over very hot coals because everyone needs to do something just a little bit whacko every now and then. 
In order to be allowed to do this feat of potential foot-destroying death, I need to raise £50 for Retrak – a charity helping street children in Africa. A worthy cause, so please give me a bit of moolah and I will burn my precious tootsies by walking on fire.
