The race
The Doomsday Run takes place on Sunday 29 November 2026 in Bere Wood, a private woodland on the Charborough Estate in Dorset opened for the event: around 600 acres of dense forest.
There are a half marathon and two-person relay (start 10:00) and a 10K (10:15), on rough ground of roots, ruts, mud and low light under the canopy. The final route and exact distances will be announced nearer the race; a GPX file is sent to entrants beforehand.
