Event Details

What’s Included

All races will be professionally timed with bib-tag timing.

All runners will receive custom finisher medals and t-shirts. There will be age-group medals for the top finishers in each category.

Raceday Logistics

Raceday Registration:

It is possible that the race is 100% sold out before race day. Updates will be posted on the race website. If you do not see the race noted as sold out here or on the race home page, you will be okay to sign up on race morning, starting at 6:45 a.m. Race day registration is an additional $5 from the final online registration price.

Bib Pick-Up:

Runners have three options for picking up their bibs and shirts:

1. Mail-out service (available for a fee when registering).
2. Pick-up in person at Road Runner Sports in Berkeley on Thursday, February 13th 3:00 pm to 7:00pm and Friday, February 14th, 11:00 am to 3:00 pm. Runners who pick their bib up in person will have the chance to enter a raffle for several prizes, including free race entries! All runners will also receive $10 off their purchases of $30 or more.
3. Pick up on race morning (not recommended).

In order to avoid race morning stress and avoid having to arrive even earlier, we strongly recommend choosing options 1 or 2. If you are unable to take advantage of those first two options, race morning pick-up will still be available, but you should aim to arrive 70-90 minutes ahead of your race start to account for lines.

Time Limits:

The half marathon will start at 8:00 am and the course will have a time limit of 4.5 hours. Runners must reach the 4th aid station (mile 10) by 11:30 am (20+ minute per mile pace).


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 hiker's 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.

Water Stations:

Water stations will be fully stocked with water, sports drink, gels, pretzels, candy, etc.

Approximate water station locations:

5K: Mile 1.25
10K: Miles 1.5, 2.9, 3.25 and 4.68
Half marathon: Miles 1.5, 2.9, 6.5, 10.2 and 11.6

Those needing water more frequently are encouraged to carry a water bottle or hydration pack.

Pace Groups:

We are happy to announce that the Trivalley Running Club will be coming out to pace the Bay Breeze and Victory half marathons! These experienced runners have paced at our Summer Breeze and Bay Breeze races in the past, helping Brazen runners achieve their personal bests! The following pace groups will be present at both races: 1:30, 1:35, 1:40, 1:45, 1:50, 1:55, 2:00, 2:10, 2:20, and 2:30.


Not ready to run, but still want to be part of the community, helping runners achieve their goals and have an awesome day? We would love your help. Sign up at:


I am a very slow runner. Am I going to be out of place?

You won't be out of place at all. Our races are planned for participants of all abilities, including walkers/hikers.

Can I wear headphones?

Yes, but we ask that you keep the volume down at a safe level so that you can hear other runners or instructions from event personnel. We also ask that you remove them, or, at the very least, remove one ear bud when you are coming to aid stations, in a large crowd or on more technical or difficult sections of the course. The important thing is paying attention to everyone's safety and maintaining basic race etiquette with other runners.

Do you offer a group discount? Frequent runner discount? Family discount? Coupon? Special break for running more than one race?

We do not.

Will there be somewhere to leave my warm-up clothes?

Yes, there will be a sweat-check area and these will be checked in and watched over by a volunteer. Bags for storing your sweats will be available if you do not bring your own. Please do not leave valuables in your sweat bags – we cannot be responsible for these items.

Can my dog run with me during the race?

Unfortunately no. As much as we love dogs and running with our own, not everyone is comfortable being around dogs (even if leashed) and for reasons of safety (for those with two legs and four) we ask runners not to bring their dogs along for the race.

Will the race be cancelled if it rains?

No. The race will be held, rain or shine. Courses may be modified to account for weather conditions.

  • Did the event in 2018

    Well organized. Great race/course, fun environment. I have ran this race at least 4 years.
  • Did the event in 2018

    Great! Very well organized and easier to park than I thought it would be. Great food, too!
  • Did the event in 2018

    It was great, the course was pretty. It was a beautiful day. I really like running the brazen races.
  • Did the event in 2018

    It was great. Set a personal record, and left immediately afterwards for brunch :-)
  • Did the event in 2018

    It was a flat route and a good weather for running!
  • Did the event in 2018

    You always put on a great race. I appreciate all you do
  • Did the event in 2018

    I thought the race was paved. Was surprised so much was gravel.
  • Did the event in 2018

    Since it is an out-and-back course along a trail, the water stations are located near the beginning, near the midway point, and then again near the end.
  • Did the event in 2018

    I had a great time at this run. The marina had plenty of parking. I got there 1 hour before the race and I had my choice of spots less than a quarter mile from the start line. The race started on time, there were plenty of water points, and great snacks at the end. Its- its is a must again next year!
