An out-and-back through the Colorado desert, this route climbs very little for a hundred-mile ultra: most of the relief happens in the opening kilometers.
5 am, at Hawkeye Trailhead, in Fruita: runners head out into the desert. The route climbs straight to its highest point, then drops for good: the rest of the course rolls gently, on desert singletrack and 4x4 track.
It passes Rustler's Loop, then follows the Colorado River on and off up to Salt Creek. The terrain switches between rock and sand, through the canyons of the Kokopelli trail network.
The route reaches Western Rim, then Jouflas Campground, at the far end of the out leg, before retracing the same path back to Hawkeye Trailhead. 20 hours, no more, for the round trip.

The organiser announces 100 km and 2,050 m of elevation gain for the 2026 edition. Plotrek's illustrative route, redrawn on OpenStreetMap paths, measures 102 km and 1,931 m of gain. It is a loop, with Hawkeye Trailhead as start and finish, Salt Creek at km 37.6 and Jouflas Campground at km 81.1.
20 hours for the 2026 edition, according to the organiser's website, read on 17 September 2026. That is the time allowed to cover the announced 100 km. Start: Hawkeye Trailhead, at 5 am. The time limit can change from one edition to the next; the organiser's rules prevail.
The highest point of Plotrek's route is at 1,640 m, at km 5.2. The high point lies between two landmarks of the course: Hawkeye Trailhead (1,427 m, km 0) and Rustler’s Loop (1,413 m, km 10.8). The start and finish are both at 1,427 m.
