Race Info
The Tucson Marathon is a point-to-point, USATF-certified course that starts at Biosphere 2 near Oracle, Arizona, and drops about 1,500 feet to the finish at Pima Community College Northwest Campus in Tucson. After two rolling miles it joins State Route 77 at mile 2.8 and follows it through Catalina, then moves onto the Cañada del Oro River Park bike path at mile 18 for the run through Oro Valley. The marathon is a Boston qualifier, and the race weekend also has a 50K, a four-person relay and a Half Marathon that starts at Golder Ranch Fire Administration in Catalina, about halfway along the marathon route. The course records are 2:12:47 for men (Riley Nedrow) and 2:38:30 for women (Obsie Birru), both set in 2024. Source
