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. Runners complete repeated laps of a loop that is 3.6 miles long with about 400 feet of elevation gain per lap. The course combines single-track trail, gravel, and a grassy lakeside loop with views of Jarrett Creek, Copper Ridge, and Camp Grier Lake.
Timing is chip based and organizers score competitors by the number of complete laps finished; partial laps are not counted. Ties are broken by the elapsed time when the last lap was completed. Runners may leave the course but must return at the same location they exited. Pacers are permitted after the first 10 hours of the event.
A main aid station and a separate water-only station serve the grassy lakeside area each lap. The main aid station in tent city offers typical ultra food with additional real food at mealtimes and some vegetarian options. The grassy field near the lake provides free tent camping for participants; RV parking is not available. Lodging options are available through Camp Grier for bunks, rooms, or cabins on site or nearby.
Awards include hand-crafted trophies for top male and female finishers and for masters categories, plus milestone awards at 25, 50, and 75 miles. All participants receive a race sweatshirt at packet pickup. Registration closes on October 24, 2026, and no refunds or transfers are allowed after July 31, 2026.
