About the Mogollon Monster 100
Aravaipa's Mogollon Monster is a qualifying-required mountain 100 with a standalone 100-mile result. The race's technical rim-country identity is distinct from its shorter weekend distances.
Course
The 102.3-mile route gains about 15,900 feet on rugged trail around the Mogollon Rim. Rocky footing, repeated climbs and remote nighttime travel make it a serious mountain race.
Race-day weather
September on the Rim can bring warm low sections, cold nights, rain or thunderstorms. Elevation changes create larger temperature swings than the Pine forecast alone suggests.
