North Downs Ultra Challenge

Join #TeamWinston for the fabulous North Downs Ultra Challenge!

The North Downs provides a fabulous challenge from a Guildford basecamp, with a looped 50 km route which takes in some of the best of the Surrey hills and the surrounding countryside. You can take it on at your pace as a walk, jog, or run – and fundraise for Winston’s Wish!

A route with some wonderful scenery and fabulous views out to the south, and easily accessible from London! Sign up as an individual or as a team; you’ll get full support all the way, plenty of food and drink, optional camping and transfers, a special medal, T shirt and celebration finish. With 25km & 10km options also available – there’s a summer challenge here for everyone! Push yourself further in 2026, take on an Ultra Challenge – the UK’s No.1 Series of treks & trail challenges.
