From the organizers
Once a thriving Chinese settlement subsisting off of shrimp fishing, China Camp is now a popular state park for boaters, runners/hikers, and mountain bikers. An extensive trail network will greet you with views of Mt. Tam, San Pablo Bay, and San Francisco Bay as you traverse twisting single-track trails, climbing up and over the peak. The courses wind along thick forests and descend out into open trails on the San Pablo Bay side of the park. Each race is relatively fast, with a nice punch of a climb beginning 1.5 miles into the course, leaving plenty of room to push it or just hike and enjoy the wild turkeys and sounds of the woods around you.
