Other trail races within 187 miles
A unique 50K format: one loop of the 10K course followed by two loops of the 20K circuit, totalling 50km with 1,313m of elevation gain on well-maintained Carolinian forest trail. Crew tents and a bag drop are available at the start/finish between loops. The 14-hour cutoff makes this an accessible but genuine ultra trail challenge.
