Race Day: October 16, 2022
The 10th running of the Clo Cow Half Marathon, 10K & 5K is set to return to 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!
Half marathon starts at 7:30 am
10K starts at 7:35 am
5K starts at 7:40 am
Please arrive early, allowing plenty of time before your start time.

Course Time Limit: Half Marathon participants are required to complete the course in 3:30.
Spectators: The best place to watch the race and cheer on runners is near the start/finish line. For the safety of all participants, spectators are not allowed to drive onto the race course. Traffic will be limited to residents only.
Course Safety: Please be aware that the course is monitored, but not closed to local traffic. The use of iPods and other music players is highly discouraged. Because the course is an out and back, we ask that all participants stay to the right shoulder of the road (unless directed otherwise by course marshals or police).
Bib Number: Pin your bib number on the front of your shirt so that it's visible to race photographers and finish line personnel.
Strollers & Pets: Due to safety concerns, strollers and pets are not permitted on the race course.
