On August 8th, join Flagstaff's oldest race, and the 2nd oldest half marathon in Arizona sponsored by Kinney. This year we are hosting our 49th annual race on our challenging and breathtakingly beautiful course. Only half marathon participants will get a commemorative finisher's medal that honors Route 66s 100th anniversary. Both 5k or half participants will receive a $34 Sweatvac Hi-Tech colorful long-sleeved shirt, free digital race photos, and admission to the FREE August 7th Fratelli's pre-race pizza party located in their Party Room directly behind their 4th Street restaurant (2120 N Fourth Street). Kid's Dash participants will get a medal. See photos and the last year's race!
The Big Brothers Big Sisters of Flagstaff Half Marathon and 5K are walker-friendly events! 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.
New for this year, we are also hosting a split-the-pot fundraiser, see details below!
The race is also part of the 22nd annual Flagstaff Running Series value package of five of Flagstaff's most iconic foot races. You can save big on the Series package of races by registering for one-stop shopping before June 14th at https://runsignup.com/Race/AZ/Flagstaff/FlagstaffRunSeries
ABSOLUTELY NO DOGS OR STROLLERS ARE ALLOWED DURING THE RACE!!!!
