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 18,000 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, and includes technical sections like the Highline, Donahue, and Myrtle Trails.

A 42K race is also offered, sharing part of the terrain. The race demands advanced endurance, with qualifying standards and volunteer service requirements, and serves as a qualifier for the Hardrock 100. Visit the organization's website for the most recent information.
