On August 8th, join Flagstaff's oldest race, and the 2nd oldest half marathon in Arizona sponsored by Kinney Construction Services! This year we are hosting our 49th annual race on our challenging and breathtakingly beautiful course. All half marathon participants will get a commemorative finisher's medal similar to last year's popular design. 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.
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 soon to be announced 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 at https://runsignup.com/Race/AZ/Flagstaff/FlagstaffRunSeries

These values represent the 3-year monthly averages for August in Flagstaff.
Flagstaff is a city of over 75,000 people (2019) near the San Francisco Peaks mountain range of northern Arizona and the Grand Canyon. At an altitude of 6,990 ft (2,130 m), Flagstaff and much of the surrounding region are substantially cooler than the low desert that dominates the southern part of the state. Though still dry by east coast standards, enough rain and snow falls in the area to allow a forest of ponderosa pine trees to cover the landscape. Winters tend to be cold, and heavy snowfall is expected on an annual basis.
