About the race

Thetford Festival of Running is a multi‑distance trail event held at High Lodge, Thetford Forest, Brandon, IP27 0AF and organised by Zig Zag Running. The event uses a single forest loop of about 5.4 km (3.4 mi) that is almost entirely off road, with approximately 12 m of climb per lap and a high point near 58 m and a low point near 46 m. All distances start together and the event operates with time cut offs, including a six hour cut off and a shorter cut off for later starts.

Distances offered include:

  • 5k
  • 10k
  • Half Marathon
  • Full Marathon
  • Ultra Marathon

The loop is designed to stack for longer distances (for example two laps for 10k). A standard heavy half marathon is set at five laps with the option to increase to six or seven laps on the day; the standard ultra is nine laps with the option to extend up to about twelve laps if time allows. An aid station with water is located at the lap point. Event registration and post‑race teas, coffee and cake are provided from Oak Lodge. Parking on the day can be discounted for participants with a QR code. The event is cupless so no disposable cups are provided on site. There is a bespoke event medal for finishers, with a lucky dip medal option where available. Twenty percent of entry fees is allocated to forest upkeep and woodland care. Virtual entries are available through the organiser's shop. Visit the organization's website for the most recent information.
