Run like a "Bad Bass" at Lake Chabot!

Join us at the beautiful Lake Chabot Marna in Castro Valley for the scenic Bad Bass 5K, 10K or Half Marathon.

Starting and ending at the Lake Chabot Marina, the 5K is almost entirely on paved trails and includes small but very runnable hills. The 10K and Half Marathon include one major climb and the Half continues with rolling hills to the finish. 10K/Half are roughly 50% on paved trail and 50% on fire trails.
