Course and logistics
The route begins at Sandy Seep Trailhead and includes open meadows, ponderosa forest, single-track trails, technical sections, and a significant climb to the summit of Mt. Elden via Christmas Tree trail and Elden Lookout trail. There is one aid station located at about 6 miles, offering water, electrolyte beverage, and additional fuel options. Cutoffs: a 2-hour cutoff at about 5 miles (summit area) and a total race cutoff of 4 hours. Parking is primitive at Sandy Seep Trailhead; high-clearance vehicles are recommended and space is limited to roughly 30 vehicles. Overflow parking is available at Elden Pueblo or the Peaks Ranger Station but may require a lengthy walk. Race rules: no pacers, no outside aid except at the official aid station, and poles are allowed but must be carried for the entire race.
