2026 Tucson Marathon - Dec 13

Point-to-point (net downhill) marathon course in Tucson with 89m elevation gain. One of the fastest Boston-qualifying courses in the country and the fastest in Arizona. The point-to-point route starts at the iconic Biosphere 2 near Oracle, around 3,900 ft of elevation, and descends through the Sonoran Desert — past towering saguaro cacti with the Santa Catalina Mountains as a constant backdrop — down through Catalina and Oro Valley to finish at Pima Community College Northwest Campus near Tucson
