Castro Valley, CA
Entry is $68 now and rises to $73 after Oct 25, 2026, so registering before then saves $5.
The races run at Lake Chabot, a reservoir park with trails that wind through open hills and tree cover. Back-to-back events are offered across the New Year holiday, with several distance options on each day, all on the same trail network. The courses suit runners who want time on their feet outdoors rather than a road loop.
