***4.5 stars*** i…read moredon't normally trek all the way out to east bay to run races, especially an event that is 40+ miles away from home, but since i was going with a group of friends and we planned to make it an all day event in livermore's wine country, with running, brunching, and wine tasting, i said "why the heck not?" also, the proceeds from this event benefit the livermore-pleasanton firefighters foundation, which supports injured and fallen firefighters, burn foundation and local charities in the tri valley area. definitely a worthy case to run/walk for! for this particular event, there was a choice of 2 distances: 1. 10k (6.2 miles) 2. 5k (3.1 miles) i originally planned to run the 10k, but later downgraded to the 5k b/c i didn't want to tire myself out for the rest of the day's festivities. note that i was able to change distances simply by calling the phone number for on your mark events, the official race organizer, and telling someone what change i wished to make. easy peasy! the pros: -VERY REASONABLE race fees, $30 for the 5k and $35 for the 10k if you register during the early bird period -takes place at WENTE VINEYARDS in livermore, a beautiful vineyard with lots of scenery, definitely a unique venue for a race -CLEAR MILE MARKERS for each race distance, in different colours so that participants could differentiate the 5k vs 10k -ACCURATELY MEASURED DISTANCE, as my garmin read 3.12 miles upon crossing the finish line which is pretty much spot on with the official 5k race distance of 3.1 miles. my friends who ran the 10k informed me that they calculated exactly 6.2 miles, which again, is spot on with the official race distance. -FORGIVING TERRAIN as most of the course took place on crushed dirt, gravel, or grass, which is easier on the joints! -FRIENDLY VOLUNTEERS directing runners in the parking area, manning aid stations along the course, and keeping the refreshments' tables well stocked after the race. i especially appreciated that every volunteer i asked a question to knew the answer, so they prepped well for race day! -FREE and EASY PARKING just inside the main gates of the vineyard and along the street -SWANKY, CLEAN PORTA-POTTIES near the parking and start/finish areas. OMG, i've never experienced such nice porta-toilets before! these individual stalls had very secure locks on the doors, FLUSHABLE toilets, liquid soap, clean running water, and paper towels. i was very impressed by the quality of these portable restrooms supplied for us runners! -COMPLIMENTARY BAG CHECK at the finish area tent (a couple minutes away from the parking and start/finish line) with volunteers to guard your bags until after the race what you get: *choice of PACKET PICKUP @ fleet feet sports in pleasanton the two days prior to the race or on site pick up the morning of. since my friends and i live in south bay, all of us arrived early for on site pickup and experienced no wait. *white, cotton, FINISHER'S SHIRT with a colourful hook & ladder race logo *GOODIE BAG filled with race schwag, a chap stick, pin, id holder, pen, key ring, discounts to local retailers. the actual bag was a reusable safeway organics bag which was very pretty. *several AID STATIONS with volunteers handing out cups of water *TONS of POST-RACE FOOD & DRINKS, including chocolate chip and oatmeal raisin cookies, mini clif bars, bags of salted pretzels, assorted muffins, jelly beans, apples, bananas, zico coconut water, coffee, and water *COMPLIMENTARY CHAIR MASSAGE, compliments of massage envy, underneath the finisher's tent (in the shade!) although i didn't have time to take advantage of this, it was definitely a nice perk! bonuses for top finishers: *a white, dri-fit shirt for the first 20 men and 20 women to cross the finish line in each distance (this is based on order of finish, not chip time) *customized finishers' medals for the top 3 men and top 3 women in each age group *a bottle of wine for the winner in each male/female age group the cons: -it was a HOT day in the tri-valley wine country, already well over 60 when the gun went off and nearly 70 when most of us finished, without a cloud in the sky or even a gentle breeze to keep us cool -the 5k course had quite a few sharp turns, with some portions on tall, thick grass, which made it difficult to accelerate -this course was also not very scenic. although we ran through sycamore park, we didn't actually see much other than trees and grass. although i was dying from the heat, i still managed to finish with a pretty good 5k time, my second best ever, placing 7th overall female, and earning the bonus dri-fit shirt, and second in my age group, earning a customized event medal. i was definitely a happy camper heading home! thank you, to on your mark events, for putting on this terrific event!

I enjoyed this local race. We did the 10k and it was my first and only trail run. The course is not…read morethrough the wineries as I initially expected, but through the trails near Wente Vineyards. Though the website says the course is fairly flat, there are a couple of steep hills, so steep you have to walk. And judging by the top finisher's times, it is not the easiest course. I remember wanting to quit after mile 3 and asking myself why was I doing this. This race benefits the firefighters of Livermore, and there were plenty of firefighter volunteers and racers. Now there's a perk for you single running ladies, come out and take pleasure in some eye candy! It's a fairly small race, probably just a few hundred. The aid stations, and post race food were good. Also, each racer is given a raffle ticket at the finish line so your chance of winning something is pretty good. My brother in law ended up winning a free round of golf for two at Wente golf course. This race isn't chipped timed which I didn't like but a well organized event and I would do again in the future.

Livermore Half Marathon is art of the ''Golden State Series'' where if you complete all 3 events…read more(Town's Half Marathon in Oakland and US Half Marathon in San Francisco also) you get an additional medal. It's for that reason that I signed up for this event, you also get Wine sampling after the event but I'm all about the bling. Sign up was easy and if you purchase the 3 event entries together you save a few bucks. as I was a Pacer for the US Half I didn't do this but still make sure you sign up early to get the best rates! This event also sells out so don't wait too long if you want to Run it. The weeks before the event I didn't get any information about the day or packet pick up but it is all located on the website. Packet Pick up: Located at the Performing Arts Bankhead Theater Plaza the day before it was easy to get to but is only from 2-8pm so if you work late or far away you need to plan accordingly. Everything is done by number so you just provide that and they look up your Bibs. As Wine tasting is part of the post race fun you get given a wrist band to prove you're of age to drink but they make you put it on right then so you ''can't give it to someone else''. Kinda silly as I had to walk around with it on for almost a day before the event. T-Shirt is cool but the sizes run large. Course: Lot's of scenery to take in as you go through various parks and Wineries, there are some mild hills but nothing too taxing. Volunteers: Fantastic! The group at mile 11 were so full of energy. Post Run: Chaotic. There were a few bites of food (Banana's, Chips, KIND bars) with drinks of Water, Coconut Water and of course 13 Wineries for those over 21. The medal is kinda cool (doubles up as a coaster but cannot be removed from the lanyard) but not very pleasant to look at, last years way much nicer. A Nice event to do for locals and if you like to collect bling.

I will start out by explaining the need for better communication amongst the participants prior to…read morerace day. We registered through snail mail to avoid the processing fees, and a week later my check was cashed and that was the only way I knew they received my payment and registration! No email to confirm, so I had to email to verify a few weeks before the event that we were registered. It took a few days to get a response and when I did I was informed in fact we were not registered! I emailed back confirmig the date my check was cashed, then reply was sent back saying our registration was misplaced but they found it. Whew! But no other information is provided prior to race day, and that's frustrating to first timers as myself. Day of Event: I will say the preparation for race day was much more organized. We arrived at 5:45am and everything was practically set up, easy to retrieve your bib with plenty of friendly volunteers. I had to ask around a lot where to go, what to do, it was our first sprint triathlon, but everyone was helpful. There is a pre race speech given by past participants who were very informative and motivating! 400 yard swim: They break you up into age and male/females. Which I liked, easier to swim next to my fellow women especially when you may be in really close proximity. I hit a few people with my arms and legs but everyone was really friendly to my apolgies. The water at Shadow Cliffs I will have to say is DISGUSTING! Seriously, just walking to the starting point of the swim, makes me gag thinking about it. Gooeuy, seaweed type algae in between your toes that goes up past your knees when you step in it! The visibility in the water is zero, but the swim not bad physcially. 3 booeys that form a sqaure with the shoreline and easy to see. I had been training a lot in a lap pool and did one one open water swim, and was prepared for this portion of the triathlon. 11 mile bike: LOVED this route! A few hills, but overall a nice flat ride with pretty views of wine courntry in Livermore/Pleasanton. Traffic is blocked off and we get the road mostly to ourselves. 3 mile run: This was torture for me, it was hot, and there were a few more hills than I expected. But water is provided along the trail, it switched back a lot, but try to follow the chalked in arrows and you will be Ok. The finish line MC was awesome, saying your name and where you are from loud and clear with enthusiasm! I finished in 1hr 32 mins, I timed myself on my watch, but for $15 extra you can request a timing chip. I didn't make my goal of 1.5 hours but was pretty close, and didn't train too much, mostly only for the swimming portion. A check off my bucketlist, and it's local so have to be appreciative to OnYourMark Events to continuing this tradation of Sprint Triathlons in the area. Just wish for better communication and a better swimming location!

The event was well organized, well staffed, had plenty friendly volunteers, and was chipped timed. Post race results and pics were made available immediately after the event and showed your times in each of the 3 disciplines and the 2 transitions. Very useful info for future events and training. The water was warmer than most pools and I never felt cold while swimming in just shorts. Check-in was quick and easy and the morning participant meeting was informative and clarified any questions you might have about the course. Easy parking and decently clean bathrooms. Great event and highly recommended. Liked it so much, I am planning on doing the August event and this time with my wife.

Wow, still only a single review?!?!?…read more Father's day, and pop gives the heads up that he's committed me to "something" on this day, just be sure to bring my running shoes. Despite the fact that I was HORRIFICALLY hung over, it's all about pop today, so I suck it up and run. Thank the heavens above he only signed me up for the 5k (there's also a 10k). The course is quick, easy, and fun with one water stop about mid way. If I had a gripe (don't I always?), it would be at the starting line. Damn people, it's a 5k! So many people took off like they were shot out of a cannon, even knocking some people over! It's Father's Day boys and girls - let's just enjoy this one. What was most important was that my dad really enjoyed himself. So much so that he says, "We should make this a tradition every year." Great crowd, great cause (benefiting Pleasanton schools), and an awesome way to start off a day that is going to be filled with the indulgences of food and beer. Just make sure you save to beer indulgences for AFTER the race and not the night before - ugh!

Terrible. Just terrible…read more Like any race, the earlier you purchase your race entry, the cheaper it is. Well, that's what one would think. With Trek, if you wait til the very last minute they will offer $1 entries to people just to fill up the space. They didn't even bother apologizing or offering a remedy for early registrants. When we sent numerous emails about this issue, they didn't even bother to respond. And, when you leave comments on facebook, they just delete them. They only care about their pocketbooks, not about the athletes that are committed to the sport. Don't support this organization! If you want to do this course, stick with the On Your Mark Events Tri for Fun and Tri for Real course. Or even the See Jane Run race. Trek Women's is crap.
