NOTE: The AZT is a technical, rocky, mostly-singletrack route that traverses long stretches of remote, waterless terrain. It is physically & mentally demanding in the best of conditions. Please plan accordingly.

The Arizona Trail 300 is a self supported, wilderness mountain biking race held on a portion of the cross state Arizona Trail. The race follows the trail as closely as possible from Mexico to Superior, AZ, covering some 300 miles of varied terrain (elevations range from 1600 to 8100 ft). The trail surface is primarily singletrack, but the race will detour on dirt and pavement to bypass Wilderness areas the trail passes through. 

This is not an organized or sanctioned event in any way. It’s simply a group of friends out to ride their bikes on the same route at the same time. We’ll probably compare times afterwards, but more importantly, we’ll compare experiences — the highs and lows the trail and mountains offered us.

All we provide is a route, a suggested start date(*) and tabulation of results. Period. There is no race organization, no checkpoints, no support system, nothing. You are completely on your own, just as you would be if you chose to ride the Arizona Trail, or any other trail, on any other day. 

(*) Anyone is welcome to ride the route at any time. We provide a suggested start date if you want others to ride with/against. ITTs (individual time trials) are encouraged and will be ranked with that year’s results. However, please, if you are going to show up on the suggested date, plan to start at the suggested time as well, out of respect for other riders. 

If you want to be included in the “results” you need to follow the rules of self-supported travel set on the rules page. This means things like support crews and water caches are not allowed. This is done in order to ensure a level playing field.

Using a GPS device is the preferred method of following the route. Cue sheets are also provided for those that do not wish to use a GPS.
