About the event

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 & finishing at our Base Camp in Henley-on-Thames, there's a Saturday night celebration BBQ & entertainment with 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 also - there's a Chiltern Challenge here for everyone!

Push yourself further and help us to support anyone affected by breast cancer.
