Mogollon Monster

The Mogollon Monster 100 is a challenging trail ultramarathon held near Pine, Arizona, about 90 minutes northeast of Phoenix. The main event is a rugged 100-mile race featuring approximately 17,000 feet of elevation gain, with climbs and descents up to 45% grade along the scenic Mogollon Rim, ranging from 5,200 to 8,000 feet in elevation. The course traverses diverse ecosystems from high Sonoran Desert to vast Ponderosa Pine forests, including technical sections like the Highline, Donahue, and Myrtle Trails. A 42K race is also offered, sharing parts of the Rim terrain. The race demands advanced endurance, with qualification and volunteer service requirements, and serves as a Hardrock 100 qualifier.
