Twas The Run Before Christmas - Thetford Forest

Twas The Run Before Christmas takes place on Sunday 13 December 2026 at High Lodge, Thetford Forest, Brandon IP27 0AF. The event offers multiple fixed-distance options on a looped course within the forest grounds; the route is a 5.3 km loop and the final route is TBC.

  • Half marathon
  • Heavy half marathon (standard 5 laps, option to change to 6 or 7 laps on the day)

There is an event cut off of six hours; a four-hour cut off applies for a later start wave. A water and aid station is located at the lap point. The course is mainly pathway with a small section of trails and woodland; road trainers are suggested but trail shoes may be useful depending on weather. The event is cupless, so participants should bring cups or bottles for refilling.
