Lake Chabot Regional Park, Castro Valley CA
Saturday, February 21st, 2026
Lake Chabot Regional Park was established in the 1960s after the reservoir had been closed to recreational use for 91 years. Today, the lake remains as an emergency water supply and is open to fishers and boaters, as it is filled with trout, catfish, bass, crappie, and other fish.
This is one of our typically faster races with less elevation and some paved sections. The course is designed for those who are looking to PR and those who are less competitive and/or just embarking on trail racing.
