Courses and logistics
Course features vary by distance. The marathon, relay and 50K start near Biosphere 2 and follow Highway AZ-77 before joining the Cañada del Oro / Canada del Oro River Park Bike Path into Oro Valley to the finish. The half marathon starts at Golder Ranch Fire Administration and follows the second half of the marathon route. Elevation and time limits are published per distance (for example, marathon net downhill ~1,493 ft; marathon time limit 7.5 hours).
Aid stations are positioned at multiple mile markers along each course and at the finish. Beast Pacing provides marathon and half marathon pacers; there are no pacers for the 50K. Marathon and 50K runners may be dropped off at the Biosphere 2 start; the half marathon requires race-provided shuttle service. Packet pickup is available the race week in Phoenix and at Pima Community College. All finishers receive a commemorative medal; awards must be picked up on-site and will not be mailed.
