The Greater Phoenix Orienteering club is excited to host our FIRST EVER Nationally Sanctioned event. This is the final event for the Tucson/Phoenix Southwest Spring Week. Since it's a first time for us, the sanctioned race will be limited to one day. GPHXO is, however, offering local meets on Saturday and Sunday evening at a nearby location.

The First Water trailhead is located about 37 miles east of Phoenix, AZ. The map terrain is lush Sonoran Desert vegetation with topography varying from moderately flat desert to rolling hills. There are some spectacular views of the Superstition Mountains to the east and south. The weather is typically sunny and dry, with a high temperature of about 70 degrees.

A full complement of classic courses will be offered. All maps will be printed at 1:10,000 scale. Due to limited on-site parking, registration is limited to 100 competitors. There will be no on-site registration for the competitive race categories.

We will be offering the following Classic courses (check back later for course details):
