Thetford Festival of Running

Thetford Festival of Running returns for its second year at High Lodge in Thetford Forest, Brandon, IP27 0AF. The event is organised by Zig Zag Running and offers multiple distance options on a compact forest course.

Distances available

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

The core route is a roughly 5.3–5.4 km loop on woodland trails and tracks, described as almost entirely off road with about 12 m of climb and elevations around 58 m high and 46 m low. The lap format means the 5k is one lap, the 10k is two laps and longer races stack laps accordingly. All distances start together and the event uses time cut offs that vary by start group.

Standard lap counts are stated for longer options: a heavy half marathon is set at five laps with day of race options to increase laps, and the standard ultra is nine laps with scope to extend up to about twelve laps depending on time available. A water aid station is positioned at the lap point. Parking is discounted to £5 for participants presenting a QR code. Registration and finish provisions are based adjacent to Oak Lodge where complimentary teas, coffee and cake are provided on completion.

The event is cupless so participants should bring their own cups or bottles. Virtual entries are offered through the Zig Zag Running shop. Twenty percent of each entry fee supports forest upkeep and woodland care. Visit the organization's website for the most recent information.
