About the race
Elden Ridge Run is a half marathon held on October 17, 2026 near Flagstaff, Arizona, starting from the Sandy Seep Trailhead. The event follows trails on and around Mt. Elden and highlights a mixture of open meadows, shaded single track, technical sections, and sustained climbing. The course begins at Sandy Seep Trailhead and proceeds onto Christmas Tree trail, then joins Elden Lookout trail for the main climb to the summit of Mt.
Elden. After the summit the route descends via the lookout tower road to Sunset trail, then continues downhill on New Heart trail past the red and orange cliffs of Little Elden. Runners loop around a knob on Little Elden trail, link into Old Little Elden, and return to Christmas Tree trail for the final mile to the parking area.
The one aid station is located at about 6 miles and offers water, electrolyte beverage, and other fuel options. Logistics and rules note a strict 2 hour cutoff at approximately 5 miles near the summit and a total race cutoff of 4 hours. Parking is at the primitive Sandy Seep Trailhead with limited spaces and high clearance recommended; a few overflow spots exist farther away. There will be no race day registration.
Other details: no pacers, no outside aid except at the official aid station, poles are allowed if carried for the entire race, bibs will not have timing chips, and two portable toilets will be available at start and finish. Visit the organization's website for the most recent information.
