Thousands of adventurers have taken on the Chiltern 50 Ultra Challenge® - part of the UK’s biggest and best series of treks and trail runs for a wide range of ages, fitness and experience levels which raises £10+ million a year for charities!

You’ll get full support all the way so you can set a new 50km goal, conquer the Full Chiltern 50 Ultra Challenge® and push yourself further for an important cause. If you’re up for a charity challenge this year, make it the Chiltern 50 Ultra Challenge®.
