The Clo Cow Half Marathon, 10K & 5K courses start and finish in the heart of Historic Downtown Petaluma. Participants will start on Kentucky Street and make a left on Western Avenue, where the route takes runners quickly into farm country. Before mile 1.5, the race turns right on Chapman Lane, where 5K runners/walkers turn around. The Half Marathon and 10K turn left on Eastman Lane (shortly after the 10K turns around) and another left on Middle Two Rock Rd. As you near mile 5, the longest hill climb on the course starts, but that is rewarded at mile 6 with an incredible view, as well as the halfway point in your journey.
Aid Stations: Runners/walkers in the 5K will pass 1 aid station. Runners in the 10K will pass 3 aid stations. Runners in the Half Marathon will pass 7 aid stations.
Restrooms: Portable restrooms are located at the start/finish line and along the course at the first 3 aid stations.
Course Time Limit: 3.5 hours
