Event details

Take on the Chiltern 50 Ultra Challenge and enjoy a stunning route through some of England’s finest countryside. Join over 1,000 Challengers taking on the distance as a walk, jog, or run, all whilst fundraising for charity and making a real difference.

Set out from basecamp in Henly and head north along historic trails and across rolling hills with fantastic views. You’ll travel on Shakespeare’s Way, the Chiltern Way, and the Icknield Way and through nature reserves known for deer and other classic English wildlife. Easily accessible from London, this is the perfect scenic day out on the trails for Challengers of all abilities.

Join as an individual or as a team and get ready to experience full support every step of the way. Regular Rest Stops packed with food & drink, hot meals, fully marked routes, massage & medical care, marshals on course and walking the route with you, and of course an unbeatable community. There are even camping & transfer options available so you can plan your whole weekend smoothly.

Join the UK’s #1 Series of treks & trail runs in 2027, and push yourself further with the Chiltern 50 Ultra Challenge.
