Course and logistics
The 100K is a continuous course with ten aid stations, about 14,200 ft of elevation gain and roughly 80% single-track trail. Its high point is about 5,820 ft and the route passes Gold Creek, the Dungeness River, Royal Creek and sections near the Buckhorn Wilderness boundary. The 100K uses many of the same trails as the 50K but in a different order.
The 50K is a single-loop course starting near 2,600 ft elevation, with about 8,600 ft of climbing and 74% single-track. The 25K is a single loop with nearly 4,000 ft of elevation change and includes a 2,250 ft climb to Mount Zion over 3.7 miles.
Aid station, drop bag, crew and pacer locations are specified for each distance. Race HQ is accessed via Forest Service roads off Route 101; expect a rough 12-mile forest road drive from the turnoff and limited cell signal after leaving Rt 101. Camping and volunteer information are provided by the organizers. Visit the organization's website for the most recent information.
