Celebrating its 10th anniversary, the Clo Cow Half Marathon, 10K and 5K is set for September 20, 2020 in Historic Downtown Petaluma. The 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!
