Treat yourself to a hair-raising hike around some of London's scary streets and historic haunts

Why not risk a hair-raising hike around some of the City’s scary streets and historic haunts. Choose your distance, make up a team or go it alone and meet up with other chilling challengers.

Dress to distress, and our creepy dungeon keepers at The Oval start and finish will meet, greet and shock. Once you escape the ghostly looped routes, with zombie rest stops, you will receive a macabre medal, glass of fizz and some hot food and drink.
