Mogollon Monster

Mogollon Monster 100 is a rugged ultramarathon weekend based near Pine, Arizona, about 90 minutes northeast of Phoenix. The event features a 100-mile race and a Sunday 42K, run along the Mogollon Rim. The course climbs from roughly 5,300 feet to about 7,900–8,000 feet with around 17,000–18,000 feet of total elevation gain, crossing the Rim six times on iconic trails such as the Highline, Donahue, and Myrtle. Expect very technical terrain, long climbs, and remote sections. The atmosphere emphasizes old‑school ultrarunning—with marker navigation, limited on‑course aid, and HAM-radio tracking—plus Hardrock qualifier status and unique crew/pacer rules.
