The marathon is a net downhill point-to-point route that starts at Biosphere 2 near Oracle, rolls through some hills to Oracle Road, then runs past Catalina and through Oro Valley to Pima Community College Northwest Campus. Net elevation loss is 1,493 feet. It is a USATF-certified Boston qualifier, and no time penalty applies. The half marathon's start is at Golder Ranch Fire Administration, from where it joins The Loop bike path beside the Cañada del Oro. The 50K follows the marathon route and adds an out and back to Ted Walker Park.
