The Mogollon Monster 100 is a challenging 100-mile trail race set just northeast of Phoenix, Arizona, near Pine. This advanced endurance race navigates the rugged Mogollon Rim, a striking geological feature that rises 2,000 feet and stretches across Arizona into New Mexico. Participants will experience significant elevation changes, ranging from 5,500 to 7,900 feet, as they traverse diverse ecosystems, transitioning from the high Sonoran Desert to the expansive Ponderosa Pine forest. Racers will encounter six rigorous climbs of the Rim while tackling a total ascent of 18,000 feet throughout the course. Known for its technical sections, particularly on the Highline, Donahue, and Myrtle Trails, this race demands resilience and adaptability. With terrain that poses unique challenges and moderate elevation, participants must prepare for fluctuating weather conditions, including potential thunderstorms and chilly nighttime temperatures at higher altitudes, amidst the stunning backdrop of fall foliage.
