I went to Bay Breeze with my girlfriend as my first ever 5k. We were both a little nervous, and our stomachs reflected that. Thankfully, we were able to find nice washrooms at the Inn on the way to the race start from the parking.
The race was very well organized (again I’ve never seen other races for comparison), we reached around the time the 10k was starting. We got some pictures and got our bibs and race swag. After a few stretches, we lined up.
As soon as the gun went off, off we went! The start was on grass and due to the rain the prior days it was all muddy and we had to be careful about not twisting an ankle or something. Once we got on the pavement, it was smooth sailing.
I was a bit behind but I slowly gained speed and ovetook people on the left off the pavement. The course was paved going to the half way mark with nice views of the bay. There were a couple supporters, photographers and people handing out waters around the 1 mile mark.
At the half way mark, you turned around and came back the same way but off the pavement. The ground was a little wet so we had to go to the pavement to avoid the water. I ended up finishing the race before the goal time of 30 mins!
Once I crossed the finish line, the volunteers handed us medals and water bottles. They had decent snacks for replenishing. We got a couple pictures from the volunteer photographers and headed back home.
Amazing first race experience!

Once over lightly … maybe? Bay Breeze starts and end in Marina Park, and is out-and-back in three distances on the Bay Trail along the bay. I did the half marathon. For the half, the course was about half paved and half packed dirty and gravel. There is almost no shade on the course. Yesterday was mostly sunny and warm, but clouds and rain are possible in February.
It’s a Brazen Race, register-and-run. Well organized, well marked course (though going off-course usually would involve a swim), ample aid stations and recovery food. Very helpful encouraging volunteers … it’s a Brazen Race.
My tech-type tee is very red, featuring an octopus holding a bouquet of red roses – combining sea and Valentines Day themes. The medal is an octopus holding an anchor on a heart background.
My finish time was not great, ~70% because of non-preparation (= being lazy), 30% sciatica (I now know things that help, but wasn’t diligent in learning). Finishing was the BIG goal, because Bay Breeze was the last half I tried and couldn’t finish in 2018 before finally trying (and finishing) another in November 2021. Vindication? Revenge? Getting it behind me and moving on? Obviously Bay Breeze will be a consideration in the future.
Great rave and great organization

It’s a flat course, 27′ incline total. I did a PB. Brazen’s got it covered as far as swag and aid stations and event tents. I had a great time and plan to do a 10K with them next, the Victory Run.

Nice course along the bay. The first 2-3 miles are paved with the majority of the course being gravel trail. Easy flat course. It rained race day and it can get a bit windy being so close to the bay. My only negative is that the tents/booths and start/finish line were on the grass. Super muddy!! Didn’t expect a PR since I basically had to walk through the start/finish. I wore a hydration vest so I didn’t have to stop at any fuel stations along the course but I heard they are great. Post race treats were plentiful and with a very good variety of snacks. Thought it was cool finish times were printed and posted up fairly quick. Medal was really cool but didn’t differentiate distances. I would run this race again!
Great course
Nice view, flat course, very fun race, I really recommend it , although it was very cold and rainy/ windy on the race day, still great course to run. MORE

This is a great flat race course. Brazen provides great support, gives great directions before race day so there are no surprises and they provide the nicest medals. Loved it. MORE

Make it happen, cap’n!
This is one of my favorite races. The 10k is a quick jaunt through the bay trails, with a view of the marsh on one side, the bay on the other.
There’s never a shortage of porta pottys!
As always, Brazen’s end of the race snacks can’t be beaten! The only thing I’d change is to have more vegan-friendly options. Before I went vegan though, the It’s It’s where my favorite!
I plan on running this race every year and have for the past 3 years. 🙂
Love the marina and this race

I’ve done the 5k and the 10k. 5k you stay pretty close to “home” and you run this one mile loop out into a peninsula in the bay that’s very pretty, then down the coast far enough to make the distance work out and then flip it around and back to the start. The 10k is more of a normal out and back. The half you make it almost to the Hayward Shoreline interpretive center.
Brazen is always awesome, usual great food and shirts and medals. No surprises there.
Nice, scenic run along the bay

Event & Course Description: Brazen Racing’s Bay Breeze starts and finishes in Marina Park in San Leandro, with half marathon, 10K, and 5K distances. I did the 10KI, but have also done the half marathon in the past. For 10K and half runners the course is easily described: head south on the Bay Trail and turn around at the designated point to head back to the finish. The 5K course adds a ~1mile loop around a small peninsula which the other distances do not do. The half marathon course is about half paved, half packed dirt and crushed gravel. The 10K course is about 2/3 paved. Much of the paved trail has shoulders of packed dirt and gravel. The course is basically flat.
One side of the course is almost always the bay. The inland side is mostly marshes, with about a quarter of a mile going past a housing complex. There are a couple of bridges along the course. Personally I’m more inclined to rocks, cliffs and breakers for sea views, but the views along the Bay Breeze course are very peaceful, and may include views of the bridges crossing to the San Francisco Peninsula (weather allowing).
Over several years, the weather for Bay Breeze has varied from sunny and relatively warm to very light rain and somewhat windy. There is basically no shade on the course. 2019’s running saw light rain for the half marathon starts, and very chilly wind. The rain had stopped when 10K and 5K runners started (guess who checked the weather forecast for rain, but not the temperature forecast … and wore a short-sleeve Tee!). Outbound, the wind was almost directly in runners’ faces. I noticed it less inbound but can’t say whether it had lessened or was less annoying coming at my back.
Organization & Production: Bay Breeze is one of Brazen’s most popular races, with over 1300 finishers of the three distances in 2019. The three distances have separate starts, with a “Hikers” start an hour before the regular half marathon start. This is for slower runners who want the extra time, and is also used by runners who want an earlier finish. Hikers are not eligible for age group or overall awards. The course for Bay Breeze is very simple, out and back. But Brazen marks its courses well, has course marshals at key points (not many for Bay Breeze), and has “Mile #” signs for each distance along the course.
Brazen’s aid stations offer a wide variety of liquids and snacks. Water and electrolyte drink are always provided, and Coke and ginger ale are also usually available. Snacks include a wide variety of candies, Payday and Rice Krispie Treat candy bars, cut up bananas and oranges, Oreo cookies, chips, and pretzels. That I can remember. If this sounds pretty much identical to my past Raves’ descriptions of aid stations, that’s because Brazen is VERY consistent. The goodies are great, but for me the best part of Brazen aid stations is the very cheery and encouraging volunteers. There is always one or two experienced aid station workers at each station, so things are generally well organized, allowing the volunteers to encourage and cheer on runners while keeping the goodies flowing.
Bib: Brazen doesn’t do plain race bibs. Bibs usually have some sort of distance color-coding. There is artwork in the background (often shared with the race T-shirt) with, running from top to bottom, the race name and date, bib number and runner’s name, and Brazen Racing’s logo. The background artwork for Bay Breeze 2019 was an octopus playing guitar to serenade his love (Valentine’s Day meets sea creature!).
T-Shirt: Brazen’s registration fee includes a tech type T-shirt for half marathon runners and a poly-cotton T-shirt for 10K and 5K runners. 10K and 5K runners can upgrade to a tech type Tee for a moderate fee (currently $7), which I did.
The tech type race T-shirt for Bay Breeze 2019 was RED (as it has been for several years) and long-sleeved. The front has the serenading octopus-of-love and guitar. The back features the artwork of a previous year, the octopus holding a bouquet of red roses for his love. The back also has sponsors’ and Brazen’s logos.
Finisher’s Medal: The medallion is a large red heart with the guitar-playing octopus-of-love in front of it, and the race information at its bottom left. The ribbon has multiple red an white stripes, with the race information in blue outlined white and blue hearts running along the length of the ribbon.
Finish & Recovery Area: Not only did it rain lightly and briefly on race day morning, it also had rained on several days the previous week. The start/finish area is all grass, except the ground was saturated, which resulted in the lanes into and from the arch being churned into mud. I saw a couple of people on Facebook who mentioned slipping and falling just after finishing, which I came close to doing. Not dangerous, just part of “rain or shine”.
Brazen does not skimp on recovery area food – candies, cookies, cakes, chips, and cut up fruit, probably 3X the variety offered at aid stations. Brazen’s “signature” finish area snack is several flavors of It’s It ice cream sandwiches. I usually go for the mint ice cream, and occasionally strawberry. It’s It recently introduced a “Chips It” sandwich, which uses chocolate chip cookies instead of oatmeal cookies. The Chips It is also not coated with chocolate. I tried and liked the Chips It.
My Results & Opinion of the Race: Brazen is one of the best race organizers in the SF Bay Area, always an excellent race experience (I’ve done 38 Brazen races in the past 5 years, so I’ll make that generalization!). Bay Breeze 2019 was all that. Bay Breeze is the first of a two-race series, and those who do the second race two weeks later, Victory, receive a connector medal that combines the two finisher’s medals into one really large “mega-medal”. I’ll be doing Victory, and doing Summer Breeze (same courses as Bay Breeze) is a possibility.

This is the third year that I’ve run this race. The race starts at the San Leandro Marina and takes you down the Marina Bay Trail towards the San Mateo Bridge. You turn around about a half mile before you hit the Hayward Shoreline Interpretive Center, and head right back up the same trail to the marina.
There’s absolutely no way to get lost on this course. It’s almost completely flat. If there’s any challenge at all, it’s that the trail becomes unpaved on the southern half of the course, if this is the sort of thing that slows you down. I personally prefer to wear shoe gaiters for this race just to keep the gravel and pebbles out.
Because the Marina is so spacious, Brazen invites a lot of vendors to set up their booths, so this race has a little more to do afterwards. There’s also plenty of parking, although if you show up later you will probably have to park a mile away near El Torito!
Plenty of aid stations, plus the post-race smorgasbord of awesome snacks.
Bay Breeze is the winter edition of this popular course. If you’d rather do this when it’s warmer, Brazen also offers the identical course in the summer in the Summer Breeze race.

Nearly all paved, and totally flat, this is a course for speed records! Well stocked for runners, there are 4 aid station stops on the 10k course – with all the goodies one generally finds at a Brazen race – fresh cut fruit, water, Ultima Replenisher electrolyte drink, chips, candy, pretzels, Gu…all sorts of stuff! This course also has port-potties near the turn-around, for those that had too much coffee before the race (me…yep…I did that!!). The trail is fairly wide, so there’s no issue when faster runners are on the way back, while those with a more relaxed pace are still on the way out. And then there is the view of the water…so peaceful, so beautiful!
The views of the Bay are worth it!

10k and half are flat with some paved but mostly packed dirt. The views of SF and the planes flying over are great. The first time I ran it it was super foggy – making it boring, but if the weather cooperates you are in for a treat!

This is a really easy flat race out at the San Leandro Marina with views during the entire race of the San Francisco Bay. Starts in a park area and can get a little muddy at the start/finish, but the other 99.9% of the race is on paved path and gravel path. This year had the most amazing rainbow (double, even) to start us off. Just a tiny amount of rain before the race started, but none after that, and when the sun came out it was really nice!!
This is a very popular race because of its location and how flat it is. There are plenty of aid stations in the half (they also do a 5k and 10k). I would recommend this race for any new runners, or seasoned folks looking for a PR.

We love running the Love Octopus (as we call it). I think my significant other and I have run it for 5 years now. We both often still wear our race shirts. The course is completely flat and fast, it’s an out and back. The only downside is that as a 10K runner trying to place, I have to try to navigate through some slower 5K runners on the way back, both sets of people running on the same course.

A valentine’s day (and cephalopod) themed run. Amazing bay views, easy flat out and back course. Even fighting a headwind for half the course didn’t put me off. As always Brazen puts on a great event – best medals, t-shirt designs and course support of any race series I’ve attended.

A great location for a first half marathon (or any event). Brazen put on a great event with pacers at a great location that follows the bay so there is plenty of wonderful scenery to distract the mind.
The post race food was also very good and the medals from Brazen are always nicely designed.

This is my Brazenversary race, 4th time running here. This year, I ran the 10k.
The last two years , I ran the half marathon. Still have not run the 5k here, yet. Nice flat and fast course which runs along the San Leandro Marina right next to the SF Bay. The course is mostly paved. There is some gravelly sections.
Brazen has top quality medals for all finishers and the top three in each age group get another medal, too. Tech tees for half marathon runners and cotton tees for 5k/10k runners. Always love their shirts. Post race refreshments consist of bagels, fruit, candy, salty snack, pastries, cookies, and an It’s It ice cream. You will not leave hungry. Plenty of aid stations on course. They are stocked with water, Ultima Sports drink, Gu, salty snack, candy, etc. Great race production. Will run again.
This is the first race in the (Bay) Breeze to Victory double medal. If you run both races, you will receive a joiner medal that will connect the two and you will have a Mega-medal.
