Update (12/29/17): We are 100% sold out!  Race day registration will NOT be available.  We wish we could allow more people in, but we have park capacities that must be respected in order to ensure the ability to put this (and other) events on in the future.  Thank you for your understanding!

There are still some spaces available for our New Year's Eve event in Fremont:


The sun is rising on Monday morning, January 1st, the first day of 2018. Where should you be? Pounding 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 2018 with the highly coveted New Year Mega Medal! Learn about the New Year's Eve race here

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"!
