Embark on a breathtaking challenge with the Elden Ridge Run, a half marathon trail race set for October 17, 2026, in the stunning landscapes of Flagstaff, AZ. Starting and finishing at the Sandy Seep Trailhead, this event promises a memorable journey through diverse and demanding terrain. Runners will begin with serene views of meadows dotted with ponderosa pines, quickly transitioning to the ascent of Mt. Elden via the Christmas Tree and Elden Lookout Trails. This climb to the summit, reaching approximately 9,000 feet, can be a test of endurance, requiring either a steady power hike or a determined run.

The reward for the climb is the exhilarating ridge-running segment, offering sweeping panoramic views of Flagstaff and the surrounding peaks. The course then plunges into a "gradual but relentless descent" along the lookout tower road to Sunset and New Heart Trails, showcasing the vibrant red and orange cliffs of Little Elden. Expect a dynamic mix of excellent single-track, technical sections, and classic Arizona rocky terrain. A single aid station, providing water, electrolyte beverages, and fuel, is strategically placed around mile 6. Be mindful of the strict 2-hour cutoff at the 5-mile summit checkpoint, ensuring a reasonable level of mountain fitness.

Typical race day conditions in mid-October in Flagstaff offer crisp autumn air, with highs around 64°F and lows near 32°F, and a minimal 5% chance of precipitation. However, be prepared for potentially gusting winds and colder temperatures at the summit. The Elden Ridge Run, now in its third year, is lauded for its challenging course and stunning fall scenery, featuring golden aspens along the ridge that truly highlight Flagstaff's natural beauty. Parking at the primitive Sandy Seep Trailhead is limited, so carpooling is highly encouraged for this exceptional trail running experience.
