Why not risk a hair-raising hike around some of the London’s scary streets and historic haunts? Choose your distance, gather your bravest friends to make up a team, or go it alone if you dare 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 you. Once you escape there’s ghostly looped routes, with zombie rest stops, and if you manage to get back in one piece there’s a macabre medal, a glass of the Devil’s fizz, some horrific hot food and drink!
