There is a 19 hour cutoff for the standard course and a 20 hour cutoff noted for the 2025 course. Historically about one third of starters finish the full distance within the cutoff.
Entry is limited to members of Sky Pilots Endurance Navigators and to runners with demonstrated mountain experience. Runners must have experience with rugged terrain, navigation, and assessing mountain weather. Support on course is very limited, some years gear such as ice axes and traction devices has been required. Much of the route is remote, rescue could take hours or days, and typical travel speeds are roughly 1 to 2 mph. Maps and GPS tracks from previous years are available for download from the event maps.
