On the 10th October 2010, I'm joining 16 employees at Hays Financial Markets to take part in the Royal Parks Half Marathon, which takes us through most of London's Royal Parks and past most of its glorious landmarks.

This comes at a price, however, and means that we have to run a considerable distance of 13.2 miles (or 21km). Why are we doing this? Please see below:

Action for Children helps the most vulnerable children and young people in the UK break through injustice, deprivation and inequality, so they can achieve their full potential. Through over 400 projects, they help 156,000 children, young people and their families every year.
