This fall will mark the 13th running of the Clo Cow Half Marathon in Downtown Petaluma, but the origins of our event date back to 2005 with the Petaluma Footrace. Who remembers running through the marina parking lot and around Shollenberger Park?

Shout out to our 10K winners, who both set course records!
Lucie James of Sausalito ran 36:46, and Anthony Cortes of Half Moon Bay ran 33:00!
