Arizona Monster 300

The Arizona Monster is a point to point ultramarathon through Southern Arizona's Sonoran desert. The course runs from Patagonia, AZ to Superior, AZ and covers 300.5 miles across National Forest lands.

The route includes measured elevation changes of 32,386 feet of gain and 33,840 feet of loss. There are 19 aid stations positioned along the course and a total cutoff of 150 hours. The terrain passes through backcountry landscapes and reaches high elevation mountains; much of the route is rugged and remote.

The Sonoran desert on this route has subtropical warmth in winter and two distinct seasons of rainfall. Those seasonal patterns create strong contrasts between dry and moist conditions and support a diverse mix of plants and animals along the way.

Registration for the event offers a payment plan option through UltraSignup that can be selected at checkout. Course maps, runner manuals, and past results are published for reference. Visit the organization's website for the most recent information.
