Course, format, crew, aid and rules
The event uses five different looped routes that start and return to a single home base. Terrain is all off-pavement - a mix of single track, dirt roads, and ATV tracks - with an average altitude just over 5,000 ft. Runners must have separate GPX files for each course and know how to use them. An RD will be on site 24/7. There will be no medical staff on site. The course may change if required by land managers.
One full sequence of all five routes is one Journey. Runners must complete four full Journeys to avoid a DNF (about 220 miles in 150 hours). Route order varies by Journey and includes preset, drawn, alternating, reversed, chosen, and ordered formats. Crew may only assist at the home base; outside contact with crew leads to disqualification. The home-base aid station provides hot and cold food options, drinks, and a small collapsible cup is provided; participants must bring other personal gear.
