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 106 miles. The race navigates its way 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 race covers roughly 106 miles climbing 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 23,000 feet along the way 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. That coupled with the additional mileage to a traditional 100 mile race, the terrain, moderate elevation, and Arizona sun, this race will certainly take it's toll on each runner. First time hundred mile runners may want to think about a different ultra for their first hundred miler. I can't stress this enough. It certainly is possible to complete this as your first, but the warning is necessary. It's going to be really tough. The terrain is very technical, rocky and remote in many areas requiring runners to be alone and self sustained for up to 9 miles between aid stations. It is strongly recommended that each runner have finished at least a 50 miler in the realm of Zane Grey 50, Jemez 50, Squaw Peak50, San Juan Solstice 50 or the like if you have not completed a hundred mile race.
As the race takes place in late September temperatures should be in the low 70's to 80's along the Rim but can be drastically lower on top of the Rim. 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.
