This ‘end of season’ 50km looped route covers some of the best of the Chilterns countryside. You can walk, jog, or run along historic trails and over rolling hills.
Starting and finishing in Henley-on-Thames, there's a Saturday night celebration BBQ at the end with entertainment and camping options.
Passing through nature reserves, forests, and a few hills with great views, it's a route with real variety and some wonderful scenery – and it's all easily accessible from London.
With 25km options, too, there’s a Chiltern Challenge here for everyone.
No matter which distance you choose or how you decide to tackle the challenge, you will get full support and hospitality all the way from the fantastic Ultra Challenges team!
Why should you sign up?
In addition to a Mental Health Foundation t-shirt, a fundraising pack and bespoke support from our Events Team, there are also some other great incentives too to sign up for this fantastic challenge.
