Grand Canyon Trail Marathon, Half-Marathon, & 5k Run/Walk

Grand Canyon Trail Marathon, Half-Marathon, & 5k Run/Walk is held in Grand Canyon Village, Arizona on October 24, 2026. The marathon (26.8 miles), the marathon relay and the half-marathon (13.4 miles) all start at 7:30 a.m., with the 5K run/walk at 8:00 a.m. The routes follow forest roads through the Kaibab National Forest near the South Rim, with views of historic sites along the way, and proceeds support local causes including the Tusayan fire department and the Grand Canyon food bank. Medals, snacks and a beer garden wait at the finish, and families with strollers are welcome in the 5K.

Two things make this harder than the labels suggest: the distances run long, at 26.8 and 13.4 miles, and the South Rim sits well above 6,000 feet. Arrive a few days early if you can, run by effort rather than by watch, and plan on 30 to 60 seconds per mile slower than your sea-level pace.
