Get involved Richmond Park Marathon Donate Fundraise Local volunteer, James Simcox, ran the Richmond Park Marathon in 4 hours and 25 minutes, knocking 11 minutes off his London Marathon time last year, despite the hills! All money raised will help us protect our British mammals. In the past twenty years many British mammals, including hedgehogs and water voles, have declined by up to two-thirds. The Mammal Society and Natural England warn that twelve British mammals are threatened with imminent extinction. We are doing what we can to help these iconic animals but we need funds so we can do more. There is still time to donate for James's valiant effort. Our heart felt thanks to James and all who support him.
