Course and logistics
The event is a single loop of just over 100 miles that travels through the Big South Fork National River and Recreation Area, crossing briefly into Kentucky and returning to Tennessee. The course includes technical single-track trails and about 14,500 ft of ascent. Runners pass sandstone arches, rockhouses, overlooks, waterfalls, and old farm and homestead sites including the No Business settlement. The race reverses direction each year, and a special buckle is awarded to runners who complete the course in both directions. The race provides a runner's manual, course map, and crew/pacer guidance; aid stations and volunteer roles are listed for the event. Visit the organization's website for the most recent information.
