Course, aid and rules
All distances use the same figure-8 "big" loop, with each big loop approximately 10 miles and about 1,000 ft of climbing. The 50K covers roughly 3,000 ft of total gain. The route uses South Plateau Loop, Firetower, the Family Bike Trail (Bucca), Logan-Keith, and the climb up Sinks. Runners pass near the pavilion aid station around 6.4 miles and must check in at the arch after completing each big loop.

Medical support is provided by HEMSI. Bibs must be worn on the front and visible at all times; bib transfers are not allowed. Distance changes to a shorter race are allowed before Wednesday, November 12 only; starting and finishing rules require finishing the distance for which a runner is registered to appear in official results.
