Runners will make their way along the trails and park roads that wind through the Newell and Lynch Canyon Open Space areas just outside American Canyon at the Lynch Canyon Trail Run Half Marathon, which starts on Lynch Road inside the park and finishes in the parking lot just off I-80. The course makes two loops around the park, and features views of Mount Diablo and Mount Tamalpais off in the distance, as well as nearby Napa Valley.
