Course, aid, and logistics

Courses change each year and are routed on Sylamore, Syllamo, and Ozark Highlands trails. Terrain is rugged singletrack with rocks, climbs, creek crossings, boulders, and varied trail surfaces. Average elevation gain is roughly 130 to 175 feet per mile, with some sections exceeding 200 feet per mile. High and low points are about 1,400 ft and 300 ft above sea level.

Aid stations are typically 4 to 9 miles apart, provide hydration, sports nutrition, solid foods, and basic first aid, and do not supply cups. Runners should carry their own water container. Pacers are allowed on the 50-mile day with no more than one pacer at a time. Drop bag and crew access vary by distance; the 50-mile has three drop locations. Camping is available on site in primitive group sites and individual sites per US Forest Service rules; sites have water and heated restrooms.

Cutoffs and awards

Cutoffs are enforced at aid stations with published time limits per day. Finishers of each stage receive a custom award; runners who finish all three days receive a commemorative "Rock." Awards ceremonies are held after each stage for overall and masters categories. Visit the organization's website for the most recent information.
