Borders 8-hour Challenge (NU Limits Running)

Borders 8-hour Challenge - Borders Forest Park, 05 Sep 2026

The Borders 8-hour Challenge is an endurance event organised by NU Limits Running Ltd on 05 Sep 2026. Participants complete as many 4.366 mile trail loops as possible within an 8 hour time limit. Each lap has approximately 480 ft of ascent and follows trail paths around Borders Forest Park; a GPX route file is available for route details.

Lap totals convert to standard distances:

• 3 laps equals a half marathon
• 6 laps equals a full marathon
• 7 or more laps qualifies as an ultra marathon

Timing is recorded using wrist-worn HuTag electronic wristbands on velcro straps. Tags register the start and finish of each lap with the event timing monitor; tags must not be covered and runners should avoid congregating at the start line to prevent false readings. Runners must check out at Basecamp to return timing chips and receive a finisher bag.

Basecamp is indicated on the GPX map and offers two 6 x 3 meter gazebos and an indoor hall for kit storage; NU Limits Running Ltd does not accept liability for lost items. Rock UK will provide onsite catering with hot food, snacks, and drinks. Parking is on Rock UK grounds with marshals directing vehicles; parking is charged and overnight options are available. Accommodation packages with Rock UK are listed for two nights and include shared kitchen and bathroom access.

Refunds and transfers follow stated timelines: refunds up to two months before the event, event transfers up to one month before (within the calendar year), and participant transfers up to one week before. Visit the organization's website for the most recent information.
