The sun is rising on January 1st. Where should you be? Hitting the trails of Lake Chabot, of course!

Join us at Lake Chabot in Castro Valley for the scenic and invigorating 5K, 10K or half marathon.

Better yet, make sure you run at the Brazen New Year’s Eve race and then you can start 2022 with the highly coveted New Year Mega Medal!

Take it even one step higher by running both half marathons (one on 12/31 and one on 1/1) and then brag to your friends: “It took me two years to finish that marathon!”

For half marathon participants who wish to hike the course and take more than 4.5 hours, we will offer a “Hiker Division” start at 7:30 am. Those starting at 7:30 should carry water as the first and second aid stations might not be 100% up and running, depending on the hikers speed. Hiker starts will not be eligible to win the race or for age group awards, but will be listed as official finishers in the Hiker Division and will still receive finisher medals.
