Join us on October 11, 2026 for the Clo Cow Half Marathon, 10K & 5K in charming Historic Downtown Petaluma! Wind your way through picturesque Sonoma County farmland and rolling hills, where friendly sheep, horses—and of course Moo-Cows—will cheer you on every step of the way. Sure, those climbs are a challenge, but the sweeping country views at the top are well worth the effort!
