Tentsmuir Forest 8 hour Challenge 2026
NU Limits Running stages an eight hour loop challenge at Tentsmuir Forest and Beach near Tayport, Fife. Participants complete as many 4.366 mile trail loops as possible within an eight hour time limit. The route is on trail paths around Tentsmuir Forest and has about 20 ft of ascent per lap. A GPX file for the route is available.
Timing uses electronic wrist tags that register each lap with the event timing system. Tags are worn on velcro wrist straps and record start and finish times for each lap; runners must avoid covering the tag and must check out with the timing partners to finalise results and collect their finisher prize at the basecamp gazebo.
Basecamp is marked on the event GPX map. It can be used for kit storage and will include two 6 by 3 metre gazebos. Spectators are allowed at basecamp. Tentsmuir operates a pay barrier parking system with a £4 daily charge.
Mandatory kit guidance includes sufficient nutrition and hydration for the duration of the event, a minimum of 500 ml fluid per hour and 60 g to 90 g of carbohydrates per hour of running, appropriate weather resistant clothing, dry clothes for after the event, and a mobile phone.
Entry details list an early price of £44.95 and a total event capacity of 250 places.
