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. Runners complete repeated laps of a single 3.6 mile loop that combines single-track trail, gravel and a grassy lake area. Each lap has about 400 feet of elevation gain. Partial laps are not counted; ranking is by number of complete laps and ties are broken by elapsed time of the last completed lap.
The grassy lake area houses the main aid station and timing tent. There is a large, well stocked aid station plus a water only station on each lap, with typical ultra food and vegetarian options. Runners wear chip enabled bibs for scoring.
Tent camping in the lakeside field is free; the tent campground officially opens Friday, October 30 at 4:00 pm. No RV spaces are available. Lodging options on or near the property are available through Camp Grier. Personal aid stations may be set up along the course behind aid canopies and the grassy field can be used for tent setups.
Event policies include no pets on site, no open fires, pack out all trash, and no sleeping tents along the course edge. Pacers are permitted after the 10 hour mark. Awards are given to the top three male and top three female finishers, top masters 40 plus and grand masters 60 plus, plus milestone awards at 25, 50 and 75 miles.
Registration and fee details are set by the organizer; no transfers or refunds are permitted after July 31, 2026. Visit the organization's website for the most recent information.
