Big Brothers Big Sisters of Flagstaff Dave McKay Memorial Half Marathon and 5K Run/Walk

This 49th annual run offers a challenging course. Climb a steep urban trail onto Observatory Mesa, following dirt roads with views of the San Francisco Peaks. It's a walker-friendly event, with an early start option. Expect most climbing early on; pace yourself if coming from lower elevations. Participants in the longer event earn a commemorative finisher's medal, and most participants receive a high-tech shirt and free race photos. Don't miss the pre-race pizza party! All proceeds benefit Big Brothers Big Sisters of Flagstaff, helping ignite the power and promise of youth through mentoring programs.
