The course is point to point, starting at the Ridge Road Trailhead and finishing at the Greenbush Group Camp Shelter. Transportation is provided from the finish to the start. Aid and access to drop bags for 50K entrants are provided at the finish and at Mile 3.5 and Mile 25, with additional water available near backcountry shelters along the route.
