All courses are run on a mix of single track, horse trail, and gravel road. The 100K distance will run the 50K loop twice. The 35K runs along Bear Creek and Settlers trail to the Overlook aid station and back. The 11K course goes to the first aid station (Gate 31) and back.
The course is made up of about a third gravel road, a third singletrack, and a third grassy horse trail. None of the terrain is particularly challenging, but there are places where rocks and roots will grab at you. Elevation is minimal with 2000ft. of change for the 100K course.
