About this race

RAIL-TRAIL DUATHLON

Shonto, Arizona – Saturday, June 20

START TIME: 7:00 a.m.

Yá'át'ééh runners!  Welcome to the Rail-Trail Duathlon 


The Rail-Trail Duathlon is a unique summertime running and biking experience on the rail-trail route near Shonto, AZ


REGISTRATION – Online registration for the event is now open and will remain open through  8 p.m. on Friday, June 19. Registration price is determined by age.  18 and Under is $10.  Adults are $60.  More details and registration can be found on the Run Sign Up registration page. 

Your registration included an event t-shirt, a Rail-Trail tower and sticker, along with course support, portable toilets, live music and a community fun run.

COURSE & AID STATIONS– The course will complete a marathon distance on the rail-trail paralleling the Black Mesa & Lake Powell rail bed.  Participants will bike roughly eight miles out from Shonto, and then ditch the bike and put on trail shoes for a 10-mile trail run leg.  Once they get back to their bikes, they will saddle up and head back to Shonto. 

 Aid stations will include Honey Stinger energy gels, salty and sweet snacks along with fresh fruit, Gatorade and water.  The course is subject to revision, at the discretion of race organizers and/or local leaders. Alternative routes may be utilized in case of bad weather.


RUNNER RESPONSIBILITIES: Runners will need to be prepared for warm summertime weather conditions and have the appropriate gear to accommodate such conditions. While thunderstorms are unlikely, they are possible.  Major stormy weather could leave participants exposed and traversing a muddy, sticky surface. Appropriate raingear and footwear is important.  Hypothermia and heat issues can both pose a real threat in the high desert in the fall season, and runners must be prepared for the potential onset of such conditions. Aid stations will have large quantities of fluids; however, runners should plan to bring their own hydration system.

LODGING/CAMPING – One of he hidden gems of the rez is a campground less than half an hour from the start line at Navajo National Monument.   If you are looking for a motel for Friday or Saturday nights, the communities of Kayenta, Tuba City and Page, Arizona (each about two hours from the high school) have multiple lodging options.  The new LaQuinta Hotel in Shonto is scheduled to be open in June, so you may want to check on that.


AWARDS – Overall and age-group awards will be presented to the top finishers and age-group awards.


WEATHER – June weather is likely to be cool at the start time, but will warm up quickly as the day goes on.


The Rail-Trail Duathlon is organized by the nonprofit organization NavajoYES
