What to Expect on Arizona Trail Race

The Arizona Trail Race is an unofficial challenge that takes place every autumn on the cross state Arizona Trail. Two distances are available. The Arizona Trail 300 is a 300 mile event that has been held every April since 2006. The Arizona Trail Race 800 is the complete traversal (Mexico->Utah) and was offered for the first time in 2010 as the AZTR750. Both events are run concurrently, starting on the same day, same time from border monument 103.

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 time(*) 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.
