Clo-Cow Half Marathon & 5K

The Petaluma Clo-Cow Half Marathon is no ordinary half-marathon. If you're tired of those boring “flat and fast” half’s, this one is for you! We take you from Historic Downtown Petaluma all the way out to some of the great farms of Sonoma County, where you will 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 of those rolling hills even more rewarding!
