Race Background and Scale
The Cocodona 250, organized by Aravaipa Running, is a 250- to 253-mile trail race starting in Black Canyon City, passing Crown King, Prescott, Jerome and Sedona, and finishing in Flagstaff. The course climbs 38,000 feet, reaching 9,241 feet on Mount Elden, and gives runners 125 hours to finish. About 395 participants entered in 2026.
