This 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!

 

Your entry includes free food and drink at regular rest stops, plus support including medics, marshals and massage. As you cross the finish line, you’ll get a glass of fizz, t-shirt, and a medal to commemorate your achievement.
