Borders eight hour Challenge (NU Limits Running)

The Borders eight hour Challenge is a timed loop event on 05 Sep 2026 organised by NU Limits Running Ltd. Participants complete as many 4.366 mile loops as possible within an eight hour time limit. Each lap includes about 480 ft of ascent and is run on trail paths around Borders Forest Park.

Timing uses electronic wristbands (HuTags on velcro straps) that record the start and finish of each lap. Tags must remain uncovered and runners should avoid congregating at the start area to prevent false readings. Runners must check out with the timing partners after finishing to finalise lap totals and finish times; finisher prizes are collected at the event basecamp gazebo.

Basecamp is located on site and offers two outdoor gazebos and an indoor hall for kit storage; the organiser does not accept liability for lost kit. Onsite catering will offer hot food, snacks and drinks. Parking is at Rock UK with a charge for daytime and overnight parking; overnight parking includes access to water and toilet facilities.

Mandatory kit includes sufficient nutrition and hydration (minimum 1500 ml fluid and about 60–90 g carbohydrates per running hour), appropriate clothing for weather, dry clothes for after the event, a mobile phone and a headtorch.

Distances:

  • 3 laps = Half Marathon
  • 6 laps = Full Marathon
  • 7 or more laps = Ultra Marathon

Refunds are available up to two months before the event. Transfers to another event are allowed up to one month before the event. Participant transfers to another runner are allowed up to one week before the event. Entry price listed until 02 Sep 2026 is £46.95. Total places: 200.
