The 2026 Tucson Marathon is a point-to-point, net-downhill road marathon starting at Biosphere 2 near Oracle and finishing at Pima Community College Northwest Campus near Tucson, descending through the Sonoran Desert with the Santa Catalina Mountains as a backdrop. It is one of the fastest Boston-qualifying courses in the US and the fastest in Arizona, with a net elevation loss of about 1,493 feet and only ~292 feet of climbing.

Why attend here

Run downhill from the iconic Biosphere 2 through the Sonoran Desert, where saguaro cacti line the route and the Santa Catalinas frame every mile. December here means crisp, sunny days perfect for exploring Tucson's Mission Garden or hiking Sabino Canyon, then warming up with a hearty bowl of Sonoran hot dog and a prickly pear margarita.
