About the Elden Ridge Run
Elden Ridge Run is a trail half marathon starting and finishing at the primitive Sandy Seep Trailhead northeast of Flagstaff, climbing Christmas Tree and Elden Lookout trails to the summit of Mt. Elden before descending via Sunset and New Heart trails back to the start. Now in its third year, the small-field event is capped by limited trailhead parking.
