REGISTRATION – Online registration for the Naatsisaan Trail Ultra is now open and will remain open until filled. There will be no on-site registration. Registration is at the Races Online website. The 50-Miler is open to runners representing tribes in the format of a “Tribal Challenge”. A tribe may enter three runners in the race, each of whom will complete the 50 mile run from Navajo Mountain High School to Rainbow Bridge, and back, and will score as a team. There is a 40-mile trail run from Navajo Mountain High School to Rainbow Bridge and back, designed for individual runners who are not part of the Tribal Challenge. A competitive 10-mile trail race and a community fun run/walk will be staged in the Navajo Mountain community area on Saturday. There will also be a Kids Run on the morning of Friday, October 27 prior to the Health & Fitness Fair for local schools. Special guest at the Fitness Fair and the following luncheon (for runners and the full contingent from each tribe) will be Billy Mills. Contact or for more information.
