North Downs 50 Ultra Challenge

We're heading to the North Downs with a fabulous challenge setting out from our Guilford basecamp. Choose your distance, and walk, jog or run the full looped 50km route, a 25km half challenge, or even the Guildford 10km. Take in some of the best of the Surrey hills, the North Downs Way, and the surrounding countryside. A route with real variety and some wonderful scenery & views – and easily accessible from London – there's a North Downs 50 Challenge for everyone!

By taking on a challenge event you'll help us support over 350 babies, children and young people who are seriously unwell – helping them, and their families, to make the most of every day.
