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. NATRA LLC organizes FREE group runs of 5 to 8 miles rotating a mix of over 75 different trails on Saturday mornings whether there is rain, snow or shine!

In our 24 years together, we have never missed a run due to Mother Nature.  We only skip Saturday runs if we are hosting, sponsoring, or providing volunteers at local races. Dogs are always welcome, but you must run with them on a leash - it is the law!  

Every year we voluntarily organize the Flagstaff Running Series value package of five races and provide aid stations at the Sedona Half Marathon, Big Brothers Big Sisters of Flagstaff Half Marathon, the Flagstaff to Grand Canyon Stagecoach Line Ultra and our Soulstice Moutain Trail Run.
