October 15, 2023
The Clo Cow Half Marathon, 10K & 5K is set for October 15, 2023 in Historic Downtown Petaluma. Our beautiful half marathon course will take you through rural Sonoma County farm country, over rolling hills where you'll be cheered on by sheep, horses, and of course our beloved Moo-Cows! The trip out there is a challenging one, but the inclines just make the views even more rewarding!
