The Mogollon Monster 100 is a rugged, challenging trail race taking place about 90 minutes northeast of Phoenix, Arizona just outside the small town of Pine, Arizona. This is an advanced degree endurance race of 100 miles with the addition of a 105 kilometer race and a 35 kilometer race in 2017! The races navigate up, down, around and through the beautiful Mogollon Rim (Pronounced: mug-ee-yun or muggy-own by locals, we'll call if MOG100 to keep it simple.)
The Rim rises out from the earth 2,000 some feet for a span of 200 miles across Arizona and into New Mexico, defining much of the eastern part of the state. This Rim takes the race from elevations of 5,500 feet at the start to upwards of 7,900 feet at the top of the Rim, changing ecosystems along the way in distinct flora changes as the elevation changes switch the scenery from high Sonoran Desert to the largest contiguous Ponderosa Pine forest in the world.
The 100 mile race climbs the Rim in four separate locations spending a lot of miles along the Rim, on top of the Rim and the challenging climbs up and down. Expect to climb a total of 22,000 feet along the way in the 100 mile race never below 5,000 feet and never above 8,000 feet in elevation. While other races are certainly at higher elevations, and/or with more climbing, they certainly do not contain as rugged a terrain that is found on this course. This is a VERY technical course in many areas, specifically the Highline Trail, Donahue and the soon to be revered, Myrtle Trail. Coupled with the mileage, the terrain, the moderate elevation, and the Arizona sun, this race will certainly take it's toll on each runner.
As the race takes place in late September temperatures should be in the low 70's to 80's below the Rim but can be drastically lower (read: below freezing) on top of the Rim at night. Thunderstorms from the summer monsoon season in Arizona are still possible and with that comes major wind, lightning and flash flood rains. Snow is a possibility, if unlikely in the higher elevations of the course. For the most part we can expect sunny skies, great temperatures and the start of some great fall foliage, especially on top of the Rim with all the ash, oak, maple along the trails.
This is not an easy race and as such, we strictly enforce qualification standards for the 100 mile event. All entrants will be required to have completed a 100 mile race or a race from this list to register for the 2017 Mogollon Monster. The qualification period for the 2017 event runs from September 1, 2014 - August 31, 2017.
