This fast and beautiful foot-race on paved road takes runners from the forests and canyons atop Mt Lemmon to the Sonoran Desert foothills of the Tucson valley. The marathon begins roughly 25 miles up the Mt Lemmon Highway near the Sawmill Run restaurant in the quaint Village of Summerhaven. The half marathon begins roughly 12 miles up the Mt Lemmon Highway near the Chihuahua picnic area. Upon reaching the bottom of the mountain, runners will make their way through the foothill community of Tanque Verde for the final mile before ending at Tanque Verde High School where finish festivities await. This event is presented by REVEL, which donates a portion of registration fees directly to the Mt Lemmon community. Registration information here .
