London Halloween Walk charity places 2025 | 25km

Thousands of walkers have taken on the London Halloween 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 25km goal, conquer the creepy capital and push yourself further for an important cause. If you’re up for a spooky charity event this year, make it the London Halloween Walk 25km!
