A brutal, but beautiful journey through the Sonoran Desert
The Arizona Monster 300 is a 304-mile point-to-point ultra through the remote backcountry of Southern Arizona. Spanning across multiple days, this Destination Trail event traverses the subtropical Sonoran Desert — home to dramatic ecological diversity and intense seasonal contrasts. With over 41,000 feet of elevation gain and nearly all of the course on rugged singletrack, this multi-day journey tests runners’ endurance, grit, and respect for the land.
This is not a lottery event — registration is first-come, first-served.
