We're Sold Out for 2022!
Celebrating our 10th anniversary, the Clo Cow Half Marathon, 10K & 5K is set for October 16, 2022 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!
