If you are looking for a super-fast, flat, easy course to set a personal record, you are probably in the wrong place. These courses have hills… lots of hills. If, however, you are looking for a great time on the trails, with beautiful scenery, awesome support and unique, high-quality shirts … MORE

    This is one of my favorite courses. It’s just under 13.6 mile with ~2,700′ of gain. It’s part of the Ultra Half Series, and it very much is an “ultra” half! This race starts and finishes at the Bear Creek Staging area at Briones Regional Park. It’s always in August which means the temps are high, but this year wasn’t too bad. It was still quite warm, but not un-bear-able. 🙂 The climbs on this race never disappoint, and the last mile is one of my favorite finishes to a race! Highly recommend! As always, the Brazen crew and volunteers are the absolute best in the business!!

    So happy to be back out at Brionnes for the Bear Creek Half Marathon. ~13.6 miles, with about 2,700′ of gain. Ending with a sweet downhill mile to finish the race (just before a tiny little climb) 🙂
    As always, Brazen puts on such an amazing event. Course is really beautiful, and tons of aid stations (4 in the half marathon) all stocked with all the goodies and drinks you’d need to keep going. Great work by the volunteers and course monitors etc. Highly recommend this race.

    Though my performance wasn’t spectacular, I was encouraged by what I was able to do at Dirty Dozen to try the 10K at Bear Creek. The elevation profile – viewable on Brazen’s webpages for the race – is quite challenging, but the major climb is early in the race, so I thought I could take it on. Yeah, no. Like all Brazen events, Bear Creek is well organized, but I’m not up to Bear Creek 10K right now. Ah, well. My daughter was with me, and we dropped out at the first aid station, a bit more than two miles in. The aid station was well equipped with liquids, goodies, and encouraging volunteers. In other words, Brazen Racing Normal. I don’t know if I’d do Bear Creek again, but it’s not due to deficient organizing or lack of beauty along the course. I’d just have to work up to the challenge.

    Brazen does it best! This run has a healthy mix of up and down, wide trail and single track, last mile is shaded, and a creek crossing with a short steep climb to the finish to keep it interesting! Brazen thinks of all the details- easy to enter on their web page, fair pricing, organized bib and shirt pick up, cool medals, good quality shirts, post race snacks, name on your bib,and free photos. They create a positive environment that makes everyone feel good about themselves and gives a sense of community. I am so happy I have found Brazen!

    It was a tough trail run with a lot of hills for me, and the narrow path was really difficult. But the views made it really worth it. I also liked the difficulty of the course, it made it feel like an adventure. Like, running through the woods of Endor.

    So after running the Dirty Half Dozen Brazen event in July, I thought I was pretty tough, and decided for my next challenge I would run Bear Creek. I knew it was hilly and it would be a challenge, but I did not know it would kick my butt so thoroughly!

    It was a hot day in Briones Regional Park, so that already made it challenging, but the 3100 ft of elevation is what really got me. You start out with some mild hills, running by some cows, and then the real hills start. Don’t even attempt to run up these hills, because I’m pretty sure it’s not possible (though based on some of the finishing times I saw, some people manage to do it, but I think they must be superhuman). The hills are TOUGH. And while some of the trail is shaded, a lot of it is not, which means you’re climbing those hills in direct sun and heat. I have asthma, which is bad enough on regular courses, and combination of the heat and the hills really kicked my butt. The uphills were so tough that my legs felt like jelly, so I was very cautious on the downhills, and only really trusted myself to run the flat parts (there aren’t many!). So I felt like I spent a lot of the course walking, which was totally not my goal—but to be honest, I felt like a winner just finishing this race! Around mile 4 I started to wonder if this would be my first DNF (that wasn’t due to injury). But I didn’t quit, and somehow I didn’t die.

    Due to the nature of trails, a few of the aid stations are pretty far apart, so definitely take your own water, and fuel if you need it. The aid stations were like heaven though – they had fruit, salty snacks, electrolyte drinks (once again I have to commend Brazen for using Ultima Replenisher! As someone who can’t have sugar, I LOVE that they use Ultima rather than one of the sugar-filled drinks!), cold water, and sometimes ice cold sponges that the volunteers will squeeze over your head, giving you a few minutes respite from the punishing heat.

    Once you make it to the end, after going through a single track trail where you have to cross a small creek (and don’t forget to high five the bear!), you finally reach the finish line, where the awesome medals and snacks await. Being a non-carb-eater, there weren’t many I could have, not to mention I was so hot and tired that I didn’t even feel like eating, but if I could have, I would have had an Its It and a massage—there was a vendor there with massage tables set up, which I should have taken advantage of—it probably would’ve made the next day hurt a little less!

    This is definitely a challenging event, and one that I’m glad I did, and proud that I finished (despite my worst half marathon finishing time EVER), but it might be a couple of years before I decide to attempt it again.

    If you like lots of hills and lots of single track, you’ll love this race! The course is challenging and beautiful – it just wasn’t my day.

    As always, Brazen puts on a fantastic race. The course was well-marked and easy to follow (even if it isn’t easy to run). The aid stations were well positioned and well stocked. And of course, the t-shirts and medals were fantastic as were the It’s-Its!

    I’ve run the 5k and the 10k on this course and they are plenty challenging. This was my first time trying to tackle the half marathon course, and even though this year’s result was sub-par, I’ll be back to try again!

    I have run Rocky Ridge, I have ran 22 miles of My Diablo but this race kicked my butt!! I actually did very well until I ran out of water at mile 8.5 (my bad planning). It was all exposed trail from this point out so by the time I got to AS 9.92 I was very dehydrated. Took forever to recoup but I did finish it!!
    Beautiful scenery!!! There are many times you are in shade but towards the second half a lot of exposed trail. We did have one creek crossing right at the end, FUN!
    Sam and Jasmin put on magnificent races. The biggest medals ever! I absolutely LOVE their tech shirts (even though female, I wear the men’s tech shirts. More shoulder room). ALWAYS creative designs for their medals and shirts AND they are different for EVERY race.
    This was a crazy hard race but the finish is always so much sweeter!!

    Second year running the half marathon course and it is one of my favorite races on the Brazen calendar. This race takes place at Briones Regional Park near Orinda. The half course is a single loop with almost 3100 ft of elevation. The official course length is 13.1 miles, but most people measured around 13.5 miles. This trail race will not disappoint. It has many miles of tree covered trails and plenty of exposed sections that will have you looking forward to the next aid station for some cold refreshing water and Ultima Sports drink. Be sure to carry water. It does get hot in the open areas. Most of the trails are wide fire roads and some single track. When you climb to the high sections of the trails, you will be rewarded with beautiful views of the surrounding area. The last 1.1 miles is a beautiful, tree-covered single track that rises in elevation. Note: there was plenty of poison oak on course this year, so be mindful of that if you run this race. Also, as you climb this last mile, you can hear race director Sam announcing the finishers. I remembered this from last year that you can hear him quite a bit out from the finish. Last year, I kept thinking, “Sam, where are you? How much further?!?!?” This year, I knew better and just kept going.
    There were four aid stations that were well stocked with water, Ultima sorts drink, Gu, sweet and salt snacks, and fruit. Aid station volunteers were very friendly and helpful. They were there ready to hand us what we needed.
    At the finish, we are handed our medals. There is plenty of finish line snacks and water. Don’t forget the famous It’s It ice cream sandwich that has become a Brazen tradition. All participants receive a cotton shirt for the 5k/10k or a tech shirt for the half marathon.
    For some insane reason this is definitely one of my favorite half marathons. If you are looking for an easy race, this is not it, but if you want a big challenge, give the Bear Creek half a shot.

    This was my first trail race, but because of how amazing it was, it was just the first of many! In fact, this was such an awesome race that I already signed up for my next Brazen.

    Yay, congrats Sarah! Awesome choice for your first trail race, though like you said not an easy one. And if you loved Bear Creek I'd definitely recommend Brazen's Ultra Half Series next year. In the meantime, if you're looking for your next trail challenge – emphasis on "challenge" – take a look at their upcoming Rocky Ridge Half in September. It's a beast, it may leave you talking to yourself, but you'll never feel more accomplished after running 13.1 miles. Keep running strong, and thanks for the excellent review! LESS

    Briones trails are home to me – ran cross country in high school and our home course was on the other side of Briones. I have completed the half (total butt-kicker) and 10k (challenging but definitely more approachable) – amazing views!!!

    There were lots of hills, mostly fire road but also single track. It was tough but exceedingly beautiful. The weather was perfect. The aide stations were well stocked with fuel and very friendly volunteers. Whatever we needed, we had help getting it. My time was slower than expected but comparable to others.

    Just like Brazen says…. it’s not nice to say you love “one child over the rest” or “one race over the others”, but this is my favorite race. It is so quaint and intimate. The staging area is small and everyone is packed inside waiting for the race to begin. If this is your first Brazen race, I guarantee you’ll leave with 50 new friends. 🙂
    The course is difficult to say the least, but finishes with the most awesome half mile of downhill single track, before heading up a couple hundred meters (or yards) to the finish. Plenty of aid stations and lots of rolling hills.
    Come do this race and I promise you will hooked on Brazen!!

    This is one of my favorite races. It is out at Briones Regional Park. It has a really quaint start/finish area. The course is measured at 3,088 feet of elevation gain, and you’ll love every bit of it. It can get a little warm, so I opted for the 7:00 am hiker start. This is one hour prior to the regular half marathon start.
    The coolest part of this race is the last one mile, which is nice downhill on a technical single track.

    You start on a small paved area but then jump on the Abrigo Valley Trail, where you’ll join the Briones Crest Trail just under mile 2. Around mile 3 you’ll hit the first Aid Station (with awesome volunteers!). You’ll then be on Lagoon Trail to Toyon Canyon Trail. Then you’ll join Orchard Trail to Alhambra Creek Trail. You’ll be on Spengler Trail, Valley Trail, and Crescent Ridge Trail. You’ll do a quick stint on Seaborg Trail, before the awesomest finish, down ~1 mile on the Bear Creek Trail, before a couple steps up to the finish area. Keep your eyes open for the inflatable bear, usually displaying a funny sign.

    Parking is $3, and I would recommend car pooling (for parking spaces, and for the environment) :). Also, the location can be a little confusing at first if you just use Google Maps. Easiest way to find the area is to put the intersection of Bear Creek Road and Briones Road in to your GPS.

    Hope to see you at next year’s Bear Creek race!

    First time running Bear Creek 1/2 marathon. This course was tough because of the heat. There is a hiker start that begins at 7am instead of the normal 8am start for those that will take longer than four hours. I choose the regular 1/2 marathon start. The temp was about 90’s by 11am. This course is hilly with about 3,000 ft of climbing. Aid stations were well stocked with the usually, water , sports drink, sweet and salty snacks, Gu, and Coca Cola. I was a tad disappointed with AS4. They did not have any water out when a group of us came through close to 11am. I did have my own fluids, but I was hoping for some cool water from a cup. All other aid stations were up to the usual great standards. The majority of the half course was on fire roads. The last mile stretch finishes along a very well shaded single track. Watch out for the poison oak because it lines the last mile of the trail. All finishers receive a nice medal. 5k and 10k runners received a cotton t-shirt and half marathoners receive a tech T. By the time I had finished, most of the other runners had gone home, but there was still plenty of post race food and It’s It to be eaten. I place 3rd in my age group. Great race, but it was tough.
