The 25th Hour Endurance Run - Old Fort, NC
The 25th Hour Endurance Run is a 25 hour timed trail event held at Camp Grier in Old Fort, North Carolina on October 31, 2026. The format ranks runners by the number of complete laps finished within 25 hours; partial laps are not counted. Runners use chip-enabled bib timing and are scored by elapsed time for tied lap totals.
The course is a 3.6 mile loop composed of single-track trail, gravel, and a grassy lake-area loop, with about 400 feet of elevation gain per lap. The main aid station and timing tent are located in the grassy lake area. There is also a water-only station each lap. The event permits personal aid setups along the course and offers space for tent camping in the lake field.
Amenities include a large, well-stocked aid station with typical ultra food and vegetarian options, free tent camping in the designated field, and lodging options through Camp Grier. Pacers are permitted after the 10-hour mark. No pets are allowed on Camp Grier property and open fires are not permitted; a campfire at the start/finish may be held if conditions allow.
Awards are presented for overall top finishers by gender, masters, and grand masters, and milestone awards are given at 25, 50, and 75 miles. All entrants receive a branded race shirt, a race sweatshirt at packet pickup, and additional swag. Entry price listed is USD 200.52. The event has a strict no-refund and no-transfer policy after July 31, 2026. Visit the organization's website for the most recent information.
