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 be supported along the way so you can tackle your 10km 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 10km!
