Course and logistics

The course is one large loop that crosses a variety of surfaces: smooth and technical singletrack, grassy double track, gravel, and a short section of pavement. It passes through multiple ecosystems, includes multiple waterfalls and stream crossings, and reaches high-elevation balds and summits above 6,000 ft. Aid stations are placed roughly every 4.5 to 9 miles. At a minimum aid stations provide water and Skratch Labs electrolyte drink; minimum food items listed include bananas, orange slices, potato chips, pretzels, PB&J, pickles, Snickers, and M&Ms.

Race rules require runners and pacers to carry specified safety gear at all times. Required items include a headlamp with backup batteries or light, a seam-sealed weatherproof jacket, an emergency bivy (an emergency blanket does not count), an insulating base layer, warm hat and gloves, an emergency whistle, a 32 oz+ hydration carrier, and the GPS tracker provided by the race. Pacers may join at aid 5 and must complete the final ~20 miles. Visit the organization's website for the most recent information.
