About the race
Brazen New Year's Day 2026 takes place at Lake Chabot in Castro Valley, California. Runners can choose from a half marathon, 10K, or 5K on Lake Chabot’s scenic trails. The course loops around the lake and is described as scenic and invigorating, offering a family-friendly atmosphere as participants kick off the new year with an active challenge.
A standout feature is the New Year Mega Medal, earned by completing both half marathons (one on December 27 and one on January 1). The event is part of Brazen’s Ultra Half Series, known for tougher, trail-heavy courses. Remote Runner options are available. Visit the organization's website for the most recent information.
