This family-friendly walking event offers frightening fancy-dress fun and silly spookiness, for ages 12 and up.

Escape the dungeons at The Oval Cricket Ground to follow looped London routes for 10k, a half marathon, or a full marathon, with zombie rest stops all along the chilling challenge.



Start and finish at The Oval Cricket Ground, Kennington Oval, London SE11 5SS



Saturday 30 October 2021

Take on a terrifying 10K in the afternoon only, or tackle a horrible half marathon or fearsome full marathon in the afternoon or evening.


Entry fees and sponsorship target

Your entry fee includes your medal, hot food, drinks and snacks, a glass of fizz, and a souvenir neck buff and bobble hat.

There is a choice of entry fees, depending on the percentage of the entry fee you choose to fund yourself. If you choose to pay less than 100%, the event provider Action Challenge pays the rest – there is no cost to Twins Trust.

  • Minimum entry fee of £10 and raise at least £225 in sponsorship
