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 23 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!

While we maintained an email list for the past 22 years, we retired it at the end of 2023. Instead, we hope you will sign up for our FREE lifetime membership through RunSignUp so that we can continue to send you a monthly email update.

Please note when registering (ignore the RENEW option), that the only required information you need to enter is your first name, last name, City, State, and Country.  You do not need to fill out the fields for your birthdate, phone number, or gender!

If you have a RunSignUp profile, you will be prompted to log in with your profile. 

If you are new to running or a seasoned veteran, come join us off-road and discover the incredible forest trails of Northern Arizona.
