The marathon course is routed through a mix of smooth single track, rocky steep climbs, ridge running, and fire road sections; course composition for the marathon is 72% dirt trail, 17% fire road, 10% dirt road. The half course follows similar terrain with 81% dirt trail. Split segments and elevation details are provided for each aid station leg.

Safety and services include marked trails with pink directional flags and red wrong-way flags, trail marshals, and remote aid stations stocked with Tailwind, water, Honey Stinger gels and waffles, and fruit. A hydration vest or bottle is required for the marathon and strongly recommended for the half because aid stations are widely spaced.
