Sign-up fee: £10 and upwards

More than just a spooky stroll, this is the most hair-raising Halloween hike around some of London’s scariest streets and historic haunts!

Choose between a wicked 10k walk and a 25-mile horrific hike, and gather together your bravest guys and ghouls to make up a team – or stride out solo for Team Lily if you dare. This is definitely an event for dressing to distress, and the organiser’s creepy dungeon keepers will be there at the Oval Cricket Ground start to meet, greet and spook you!

Once you escape their clutches, there’s a ghostly looped route back to the Oval dotted with zombie rest stops. If you make it back unscathed, a macabre medal, a glass of the Devil’s fizz and some horrific hot food and drink will await you.
