11 AM finishing time cut-off!  This gives competitive runners 3 hours and 30 minutes to finish the race.  If you need extra time, we offer a 6 AM early start. For early starters, finisher medals are awarded, but you will not be eligible for age division awards.  

Competition for teams with the most participants!  Runners/walkers on the largest corporate or friends/family team will win a 20% discount on next year's race!  

The race is also part of the Flagstaff Running Series value package that will be announced in mid-February. If you do not plan to register for the value package, you can save $10 by registering on this site through February 28th! 

We will again have a non-binary division for the Half Marathon and 5K. This will be one division in each race (no age groups) and you will see the radio button to identify yourself as a non-binary runner.  

ONLINE REGISTRATION CLOSES AUGUST 7th, however, you can register at the Run Flagstaff packet pickup on Thursday August 8th, 2:30 to 5:30 PM 204 East Route 66, or the night before the race at Grand Canyon Adventures 5:30 to 7:30 PM (400 South Malapais Lane).  THERE WILL BE VERY LIMITED RACE-DAY REGISTRATION, AND YOU MUST ARRIVE BETWEEN 6 AND 6:45 AM; WE WILL SHUT REGISTRATION DOWN AT 7 AM.  RACE DAY REGISTRANTS ARE NOT GUARANTEED A SHIRT!!!!  

Our beautiful course starts at Thorpe Park (do note no longer Wheeler Park!) and climbs the steep urban trail onto Observatory Mesa (where astronomers discovered Pluto) and follows dirt roads on with spectacular views of the San Francisco Peaks. Elevations range between 6957 ft at the start, to 7731 ft near the 7.5 mile mark! Most of the climbing is done over the first 1.25 miles, so pace yourself. If you are from lower elevations, heed the race director's advice and power walk!!!! You will easily make up the time over the rest of the course!  The 5K is also on Observatory Mesa. ALL proceeds benefit BBBSF Mentoring Programs that create and support one-to-one mentoring relationships that ignite the power and promise of youth.
