Meets are generally held every other week starting in late January. Most of them are in the Phoenix area. There is a meet in Flagstaff on President's weekend in February (don't worry it's indoors).

If a runner or relay team qualifies for Regionals, they may run in Colorado, Texas, or New Mexico. The 2019 Regional meet location will be in El Paso, Texas.

Cross Country Regionals are in Arizona in 2018. If  you run in the state meet your automatically qualify for Regionals in Cross Country. Nationals are in Reno, Nevada in December.

The 2019 Arizona USATF schedule has been released. Here is a link to their website for when they do. Despite the schedule stating that Regionals are in New Mexico, I have been told they are in El Paso.
