Welcome to the VIRTUAL Naatsisaan Ultra and LIVE 15-Miler & 10K Trail Race!
The Navajo Mountain Chapter and NavajoYES are excited to share 
the 5th annual Naatsisaan Trail Ultra with you on Halloween weekend! 


We have developed a comprehensive plan for creating a safe event, while staying within tribal guidelines for public gatherings/events. Together, we will make this a safe and successful event for runners and the Naatsisaan community. 

Here is the plan for the weeken:d

  • 10K Trail Run LIVE EVENT – Runners may do the 10K on THURSDAY or FRIDAY on a set course that begins and ends at Navajo Mountain High School.  Runners may begin their 10K between noon and 4 p.m. on Thursday, or between 9:00 a.m. and 2:00 p.m. on Friday.
  • 15-Miler Trail Race LIVE EVENT – Runners may complete the 15-miler course during the same race windows on Thursday and Friday.
  • VIRTUAL 50K Virtual Race – SATURDAY, 7:00 a.m. The race starts at the same time for everyone but it is a VIRTUAL event, so runners can do it on their own course.


  • Registration for the Naatsisaan Ultra 50K is now open online and will remain open through 11:59 p.m. on Friday, October 30.  Race t-shirts, race bibs, various race swag and overall/age-group awards will all be shipped to runners after the event.
  • Registration for the 10K is now open online and will remain open through Wednesday at 11:59 p.m.  There will be on-site registration for the 10K and 15-miler.  Local runners may use the code “LOCAL” for a comp entry to the event.  The Virtual 50K will remain open through 11:59 on Friday night.

   Any questions regarding registration should be directed to Josh at or


The 50K is a virtual event, so the course is literally what you make it.  

The competitive 10K and 15-miler trail races are scenic and tough runs on local dirt roads and trails; there are overall and age-group awards for this event.   The 10K and 15-miler will begin and end at Navajo Mountain High School.

The course is marked with pin flags, cones and signage; however, it is recommended that runners study the course map and be familiar with the route

This is a cupless event so runners should plan to bring their own hydration system.  There will be fluids on the course, but you will need a cup, hydration pack or bottle to be filled at the aid stations.

PACKET PICK-UP – Runners will be able to pick up their race packets in a very COVID-safe manner near the start line at Navajo Mountain High School.

LODGING – Camping will not be available at this year’s Naatsisaan Ultra due to Navajo Nation curfews and lockdowns.  There is camping available in Page, Arizona and Monument Valley, Utah (about two hours), and there is ample lodging in Kayenta, Page and Tuba City, Arizona (each also about two hours from the chapter house).

AWARDS – Overall and age-group awards will be presented in the 50K, 15-miler and 10K.  

WEATHER – The weather in the Navajo Mountain area, including the surrounding canyons, can be very volatile.  Runners should be prepared for rapid changes in conditions, including rainy conditions, wind, snow and cold.  Conversely and less likely, there may be opportunities for heat issues on this route, even in late October. Please be aware of your surroundings and be prepared for any extreme weather and trail conditions that may arise.

The Naatsisaan Trail Ultra and the Navajo Parks Race Series are organized by the nonprofit organization NavajoYES in collaboration with Navajo Parks & Recreation.  The event has major sponsorship and/or logistical support from Navajo Mountain Chapter, the Navajo Rangers, Utah Navajo Health System, Kayenta Fire, Honey Stinger, Navajo EMS and Teec Nos Pos Trading Post.
