Welcome to Northern Arizona Trail Runners Association (NATRA LLC). Founded in fall 2001, NATRA’s mission is to promote trail running in Northern Arizona to folks of all abilities. We organize group runs of 5 to 8 miles at various trails on Saturday mornings whether there is rain, snow, or shine! Dogs are always welcome, but you must run with them on a leash - it is the law! Also, remember that after all runs we convene at various coffee shops so bring a few bucks along! If you are new to running or a seasoned veteran, come join us off-road and discover the incredible forest trails of Northern Arizona.
