Running Races in Flagstaff, Arizona

Flagstaff's high-altitude trail running scene runs on real elevation: the Flagstaff Marathon climbs to 8,000+ feet through the Coconino National Forest, and Babbitt's Backyard Ultra pits runners against a last-one-standing format at Northern Arizona's volcanic SP Crater. Beyond the trail races, the Dave McKay Memorial Half Marathon and Route 66 UltraRun round out a calendar built for altitude training and serious mileage. Here are the upcoming races in Flagstaff, updated weekly.
