Courses and race details
- 66.6 km - cumulative climb close to 6,000 ft; four major climbs; cut-off 12.5 hours.
- 33.3 km - cumulative climb around 2,500 ft; cut-off 12 hours.
- 16.66 km - cumulative climb close to 1,200 ft.
All three courses include the Devil's Glen ski-hill climb and a section that requires crawling through the "keyhole" on the Keyhole Side Trail (an option to take a longer bypass exists). Terrain is described as highly technical with steep climbs and long, steep descents; participants should expect slow kilometers in some sections and hot, buggy conditions. GPX files are provided for each course.
Aid stations will be spaced less than 10 km apart and will offer electrolyte drinks, salty and sweet snacks, pickles, and sandwiches. The event is cup-less; runners must carry a collapsible cup or bottle for aid-station fills. Participants receive a race kit that includes a race bib, shirt, sticker, a Skeleton Key that must be carried and shown during the race, and a finisher medal.
