All races start and finish in the Quarry Lakes. The marathon, half marathon and 10K have large out-and-back sections on the Alameda Creek Trail. The course is mostly gravel/fire trail with a very small portion of pavement at the beginning and end. Hills are nearly non-existent, so bring on the speed!

This event is held close to my heart! As a way to honor my father, Richard Limb. I created and named this event after him. My dad has always been a king to me. I remember him sharing stories of his running in Santa Teresa County Park when he was young and the love he had for it.

Rising up from the depths of Lake Chabot, the Bad Bass (a strangely kilt-wearing, bagpipe-playing Scottish bass with teeth) shows itself once again! Why is he Scottish? What is he doing in Castro Valley? How can he play bagpipes with his fin? We have no idea how to answer those questions. Why is he so bad-to-the-fishbone? Maybe he just knows how awesome the trails of Lake Chabot really are! Whatever the Bad Bass is doing here, we hope you'll join us at the beautiful Lake Chabot Marina in Castro Valley for the scenic Bad Bass 5K, 10K or Half Marathon!
