The 9th running of the Clo-Cow Half Marathon, 10K & 5K is set for September 15, 2019 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!
