Cannonball Running Festival - Marathon, Half Marathon, 10K & 5K 2026

The Cannonball Running Festival begins and ends in Country Park in Greensboro, North Carolina. Races utilize the A & Y Greenway and park roads. This event spans a Friday and Saturday, offering a marathon, half marathon, 10K, 5K run/walk, Kids Dash, a virtual option, and the Double Barrel Challenge for participants completing two races. The Double Barrel Challenge links the Friday night 5K with a Saturday race, with distinct options for marathon, half marathon, and 10K participants. The event fosters a post-race gathering atmosphere: local craft breweries serve runners and spectators on Saturday, race registration includes two craft brews, and proceeds from spectator beer sales benefit Brenner Children's.
