About the Grand Canyon Trail Marathon
The Grand Canyon Trail Marathon is held in late October in Tusayan, Arizona, a few miles south of the Grand Canyon's South Rim. It starts and finishes at the IMAX Visitor Center and follows Kaibab National Forest dirt roads, a paved stretch of the Arizona Trail and a short sidewalk section through town. The marathon is two laps of the half marathon loop, which climbs about 555 feet per lap and tops out near 6,730 feet, and the organizers say both distances run slightly long. Run Tucson produces the event with the Town of Tusayan, and the full marathon was added in 2025.
