Choose from the 100-mile solo run, 55K solo run, and 100-mile solo mountain bike ride. Run or ride the Arizona Trail from Flagstaff, Arizona to the Grand Canyon across the ancestral lands of the Hopi, Zuni, Havasupai, Hualapai, Southern Paiute, Navajo and many other indigenous people. The racecourse roughly follows the historic stagecoach line tourists took to reach the Grand Canyon in the 1890s. The route includes singletrack, doubletrack, and forest roads along the Arizona National Scenic Trail through high desert and alpine terrain. We’ve added more trail miles for 2021 for the 100-mile runners and MTBers.

Run or ride through expansive ponderosa pine and piñon-juniper forests, grasslands, and golden leafed aspen stands. The course starts near 7,500 feet and reaches a maximum elevation near 9,000 feet. The 100-mile has about 7,000 feet of gain. The 55k has roughly 2,300 feet of gain. There’s a 31-hour cut-off for 100-mile runners and 15-hours to complete the 100-mile bike ride. 55k runners have 9.5 hours to complete the course.  If you’re interested in moving your body across ultra distances filled with some of the most iconic scenery in the West, join us!
