London Summer Walk charity places 2026

Thousands of adventurers have taken on the London Summer Walk or an Ultra Challenge® - 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 goal, conquer the capital and push yourself further for an important cause. If you’re up for a charity challenge event this year, make it the London Summer Walk!

The Ultra Challenge Experience

Walk at your own pace. The level of support enables you to go further. There are rest stops, lots of food and drink, medical and massage teams, with a fully signed route to guide you.

A big finish-line celebration with hot food, bar and music awaits with an amazing sense of achievement for you personally and also for your fundraising efforts.
