Humanity Direct Chiltern Challenge 2025

Join us this summer for the Humanity Direct Chiltern Challenge, an experience through some of the most stunning countryside in the South East.

With three distances to choose from – 10km, 25km or 50km – this event is designed for everyone, whether you're taking your first steps onto the trails or pushing for a personal best.

You’ll be supported every step of the way with our legendary XNRG care – fully-stocked checkpoints, a friendly team, and a welcoming community atmosphere that keeps people coming back year after year.

Whether you’re walking, jogging, or running, the Chiltern Challenge is all about testing yourself on your own terms and loving every minute of it.

What's more, it's FREE to run, if you commit to raising funds for Humanity Direct.
