Course, rules, and logistics

Aid stations are limited and spaced far apart because of the remote location; stations are located at start/finish or turnaround points, approximately 24 miles apart, and provide water, electrolytes, and light snacks. Runners are expected to be largely self-sufficient and to carry nutrition and supplies. Mandatory gear includes water, a GPS or map, a first aid kit, and extra layers. Cut-off times apply at specified checkpoints. Weather in the area can be variable, including sun, rain, strong winds, or snow, so participants should prepare for changing conditions. The event operates under a free permit with the U.S. Forest Service, with a suggested $90 donation per individual or per relay team to support local nonprofits. Volunteers are requested for the event. Visit the organization's website for the most recent information.
