The course follows trails around Jenkinson Lake. Most sections are single track with gently rolling hills, mixed with flat wide sections and short paved segments. The route begins with a short downhill on gravel followed by a steep quarter-mile climb, then follows relatively flat trails near the lake in a counterclockwise direction. Some sections are technical with rocks and roots.

Two aid stations serve the longer distances, located near the finish area and at Hazel Creek. Porta potties are available at the start and restrooms are available at the Waterfall Trailhead. All finishers receive a medal. Visit the organization's website for the most recent information.
