Event Description

Rising up from the depths of Lake Chabot, the Bad Bass shows itself once a year! Join us at the beautiful Lake Chabot Marina in Castro Valley for the scenic Bad Bass 5K, 10K or Half Marathon.

Beginning and ending at the Lake Chabot Marina, all courses include rolling, but mostly runnable hills. The 5K will be almost entirely on paved trails around the lake. The 10K and half marathon are roughly 50% on paved trail and 50% on fire trails.
