Mogollon Monster Trail Runs
The Mogollon Monster Trail Runs take place on the Mogollon Rim near Pine, Arizona on September 11–12, 2027. The event offers two distances:
- 100.9 mile race with significant climbing.
- 42K (26.7 mile) race.
The 100.9 mile course climbs the rim six times and lists a total elevation gain of about 15,900 feet, with maximum elevations near 7,912 feet and typical elevations between roughly 5,200 and 8,000 feet. The 42K lists about 4,554 feet of gain and a maximum elevation near 7,480 feet. Much of the terrain follows the Highline Trail and a mix of single track, forest roads, steep switchbacks and rocky sections; named technical segments include Highline, Donahue, Myrtle and Promontory sections.
Aid stations provide water, electrolyte drinks, hot food options and a range of snacks; drop bag locations for the 100 mile include Fish Hatchery, Buck Springs and Geronimo. Crew and pacer access is limited and varies by location; the 42K does not allow crews or pacers. The 100 mile has entry requirements and event rules: entrants must have completed at least a 50 mile race previously, and the 100 mile includes an eight hour volunteer work requirement prior to race day. Parking and shuttle service use a large Old Pine Parking Area with shuttles to the start; some trailhead lots do not permit parking.
Weather in mid September can vary widely across elevations, with possible violent afternoon storms and temperature differences between the rim top and lower elevations. Visit the organization's website for the most recent information.
