The course uses eight 12.5 mile loops, with approximately 1350 feet of elevation gain per loop. The surface is a mix of single track and dirt roads (about 75% single track, 25% dirt road). The course is marked with reflective tape and reflective arrows. There are two fully stocked aid stations per loop, located roughly 6 miles apart, offering hot food, vegan and gluten free options, and Tailwind. Massage therapists and a reflexologist will be available in the start/finish area.

Logistics: pacing is allowed after 50 miles for the 100M and the 100K; pacers are not allowed for the 50M or 50K. Drop bags will be staged under a canopy after each loop.
