Course and facilities
The route uses a 5.0 km loop within the grounds of Thetford Forest; the final route is to be confirmed. The course is mainly pathway with a small section of trails and woodland and is described as mainly flat with a few rises. Lap formats are used: a standard half marathon is five laps (options to change to six or seven laps on the day) and a standard ultra is nine laps (with the option to increase, up to 12 laps, according to time available). A six-hour event cut off applies; a four-hour cut off applies for later starts.
There will be a water aid station at the lap point. The event is cupless, so participants should bring cups or bottles for refilling. Registration and post-race refreshments will be based adjacent to Oak Lodge, where complimentary teas, coffee and cake are provided on completion.
