Elden Ridge Run : Flagstaff, Arizona (October 2027)
This is a trail half marathon held in Flagstaff, Arizona, with the course starting and finishing at the Sandy Seep trailhead. The route passes through meadows with ponderosas, crosses a power line access road, and follows Christmas Tree trail into shaded single track before joining Elden Lookout trail for the climb to the summit of Mt. Elden. After the summit, the course descends the lookout tower road to Sunset trail, then continues with a gradual but sustained descent on New Heart trail alongside the red and orange cliffs of Little Elden.
An aid station is located at about 6 miles into the race, roughly one mile below the summit, offering water, electrolyte beverage, and other fuel options. A second aid station is positioned after the descent near the Little Elden knob, with additional liquid and edible fuel. The remainder of the course follows Old Little Elden and returns toward Christmas Tree trail for the final mile, which is a gradual descent back to the parking area.
Logistics and rules noted by the organizer include limited primitive parking (room for about 30 vehicles; high clearance recommended; overflow options require a longer walk), no race day registration, no pacers, and a restriction that aid may be received only from race volunteers at established aid stations. Poles are permitted but must be carried for the entire race. Bibs will not have timing chips and results use gun times only. Portable toilets with sanitizer will be at start/finish; there is no running water. Registration opens June 1, 2027. Cutoffs and prizes are listed as TBD; refunds are not offered.
