Festival style season-finisher on 24 September 2022

This 50 km looped route covers some of the best of the Chilterns countryside, with historic trails, rolling hills, nature reserves, and fantastic views. Starting & finishing at our base-camp in Henley-on-Thames, there’s a Saturday night celebration BBQ & entertainment with camping options. It’s a route with real variety and some wonderful scenery – and it’s all easily accessible from London. 

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, tshirt, and a medal to commemorate your achievement. You’ll get full support & hospitality all the way, and with a 25 km option also – there’s a Chiltern Challenge for everyone!
