Royal Parks Half Marathon Why not challenge yourself and take part in a half marathon? We have two to choose from this October, one in London's Royal Parks and another in Oxford. The Royal Parks Half is always a great run, through some great scenery. The stunning 13.1 mile route takes in the capital’s world-famous landmarks on closed roads, and four of London’s eight Royal Parks – Hyde Park, The Green Park, St James’s Park and Kensington Gardens. We have charity places for our most ambitious fundraisers. Contact us here to find out more. After we have registered you, you can set up your own fundraising page on this website and email your friends direct.
