Brazen New Year's Day 2027

Brazen New Year's Day takes place on January 1, 2027 at Lake Chabot in Castro Valley, California. The event offers trail running on the Lake Chabot area and multiple distance options. The listed venue address is 17936 Lake Chabot Lane, Castro Valley, CA 94546, United States.

Distances offered include:

  • 10K
  • 5K

The event also lists a Remote Runner option and a HIKER DIVISION for those who plan to walk the half marathon. A separate hiker start is available for participants who expect the half marathon to take about 3.5 to 4 hours or longer.

Registration fees are tiered by date and include mandatory charges. Sample fee points shown for the event include early and later registration amounts for each distance and option. The event materials note a connection with a Brazen New Year's Eve half marathon; completing the half marathon on 12/31 and again on 1/1 produces the combined distance of a full marathon.
