The 5K is a mix of road and trail, listed as 3.43 miles with 243 ft elevation change.

Aid stations are located at specified mile points on both loops, with some stations stocked fully and others water only. Time cutoffs: 100K - 37 hours; 50-mile - 35 hours; 25-mile - 35 hours; shorter distances have no cutoff. Pacers are permitted after completion of the third loop (mile 38.5).
