DON'T STAY UP TOO LATE!

Ultra Half Series Championship points are up for grabs!

START 2024 THE RIGHT WAY!

The sun is rising on January 1st, 2024. 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 2024 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!"

BRAZEN ULTRA HALF SERIES

Our New Year's Day race is part of the Brazen Ultra Half Series. All half marathon runners are invited to participate.

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!
