Flagstaff Doggie Dash & BuffaLoops Ultra 2026

Buffalo Park in Flagstaff, Arizona, hosts the Flagstaff Doggie Dash & BuffaLoops Ultra. This event combines a dog-friendly 5k with timed loop racing for those seeking an extended challenge. Participants in the 5k can run with their dogs or individually. The BuffaLoops portion provides 3-hour, 6-hour, and 12-hour timed races focused on completing as many loops as possible. The event takes place annually in May, with registration managed via UltraSignup. The 5k course consists of one counter-clockwise loop of Buffalo Park combined with a one-mile loop, concluding at the starting point. Ultra runners navigate a two-mile outer loop, beginning clockwise and reversing direction every two hours to vary the experience. This format is well-suited for timed events, offering runners a personal drop bag area and the option for tents or canopies upon request. A free kids' race, games, raffle prizes, and artwork from Barking Goat Studios are available for families. Proceeds from all 5k-with-dog registrations benefit High Country Humane, directly linking the dog-centric theme to a local animal welfare cause.
