Those who would like to take their time on our beautiful but challenging half-marathon course, there is a 6 AM start. While you will receive a chip time and finisher's medal, you will not be eligible for age division awards. For many reasons, we do not allow dogs on the course during the race. Our beautiful course starts at Thorpe 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. The race is also part of the 22nd annual Flagstaff Running Series value package of five of Flagstaff's most iconic foot races.
