This is a self-supported grassroots event. No entry fee, no prizes, no aid stations. Simply you, your bike on the trail under your own power.

This is the kickoff event to the AES race calendar held in conjunction with the shuttled Gila100. In recent years the route has been ridden in a CW direction, but it can be done CCW as well. In the CW direction the route begins with a neutral rollout over the first 10 miles of pavement. The frenzy begins when the route turns north onto Willow Springs road. A short piece of the famed 24 Hour in the Old Pueblo course is used and links up to the primitive Painter Boy trail. Route finding skills are essential through here, know how to read & use a GPS! More dirt road follows, the final 27 miles are on the Arizona Trail. This section is beautiful, remote, rugged and very challenging. The AZT consists of singletrack, jeep roads, wash crossings and plenty of hike-a-bike opportunities. Cross under the Tiger Mine trailhead sign and celebrate a ride well done.
