Are you ready to rock the loch?
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!
July 27, 2019 (THE CLOCH IS TICKING)
All half marathon runners are invited to participate in the Brazen Ultra Half Series.
The series consists of our toughest half marathons. Most measure at least a little (and sometime more than just a little) longer than 13.1 miles. What really makes them "ultra", however is the serious ascents and descents and variety of tough trails you have to run to finish them. While flat half marathons are always a challenge, these "ultra-half-marathons" take it to another level!
