The 25th Hour Endurance Run
The 25th Hour Endurance Run is a 25 hour timed trail event held at Camp Grier in Old Fort, NC on October 31, 2026. The event is scored by the number of complete laps each runner finishes; partial laps are not counted and ties are broken by the elapsed time when the last lap was completed.
The course is a 3.6 mile loop that combines single track, gravel, and a grassy loop near the lake. Each loop has about 400 feet of elevation gain. The official aid station and timing tent are located in the grassy lake area. A main aid station in tent city provides water each lap plus a fully stocked aid tent with typical ultra food and some vegetarian options.
Tent camping in the grassy field is free; this area is intended for runners, crew, and family. There is space along the course for personal aid stations. No RV space is available. Lodging options are offered through Camp Grier.
Race rules note that runners may leave and rejoin the course only at the same location, pacers are permitted after the ten hour mark, and all runners will use a chip enabled bib with timing provided by a professional timing company. Pets and open fires are not permitted on site. Awards include milestone recognitions at 25, 50, and 75 miles and handcrafted awards for top finishers in age categories. All runners receive a sweatshirt at packet pickup.
There will be no transfers or refunds for new entrants after July 31, 2026 and the stated refund policy disallows refunds or transfers after that date. Visit the organization's website for the most recent information.
