Halloween Walk | Royal Free Charity

Halloween Walk

25 October 2025 
Evening ground shot looking up at Big Ben, with the clock face coloured in orange, and a spooky tree in front of it.
Join us for this year’s spine-tingling Halloween Walk and help raise vital funds for patients, staff and researchers at the Royal Free London. 

Take part solo – if you’re brave enough – or rally your ghoulish gang for a frightful team adventure!

Choose your distance, don your most distressing costume and meet other chilling challengers at The Oval, where dungeon keepers will be ready to greet you at the start and finish.

Once you escape the gates, follow eerie looped routes past zombie-infested rest stops. Survive the journey and you’ll be rewarded with a macabre medal, a glass of the Devil’s fizz and some hauntingly good hot food and drink.

Are you ready to walk through the darkness?
