Borders 8-hour Challenge (NU Limits Running)

The event on 05 Sep 2026 is an eight-hour trail challenge in Borders Forest Park. Participants complete as many 4.366 mile loops as possible within the eight-hour time limit. Each lap has about 480 ft of ascent and the full route is on trail paths.

Distances:

• 3 laps = Half Marathon
• 6 laps = Full Marathon
• 7+ laps = Ultra Marathon

Runners wear electronic wristbands (HuTags on velcro straps) that record the start and finish of each lap and provide a final lap count. Tags must be worn on the wrist and remain uncovered to ensure accurate readings. Runners must check out at Basecamp after finishing to finalise lap counts and receive a finisher bag.

Basecamp includes two 6 x 3 metre gazebos and an indoor hall for kit storage; the organiser does not accept liability for lost items. Spectators are welcome. Onsite catering will provide hot food, snacks and drinks. Parking on the Rock UK grounds is charged at £5 per day and £15 per night for campervans, with access to water and toilet facilities. Accommodation options are available at Rock UK with two-night rates showing a range of prices for bunk rooms and self-contained lodges.

Mandatory kit includes at least 1500 ml fluid, 60–90 g carbohydrates per running hour, appropriate clothing, dry end-of-event clothes, a mobile phone and a headtorch.
