If you found a performance supplement that enhanced the functions and performance of your body's three energy production pathways, and also effectively buffered lactic acid, you'd take it, wouldn't you? Hammer Nutrition's Race Day Boost is that product - and yes, it's safe and legal! In the most extensive study to date on Race Day Boost's primary ingredient, fit cyclists in a 40K time trial netted a whopping 8% improvement in performance time. The simple formula belies its profound effectiveness, aiding in increased cellular energy production and buffering performance-robbing lactic acid.
No matter what duration your event may be, a four-day loading dose of Race Day Boost prior to a key race can make a noticeable difference in your performance. This is a special product for special events, but if you intend to meet or exceed your race day expectations, you better have Race Day Boost in your arsenal.

Huge PR!! Legs felt great!I was always hesitant about this product but decided to give it a shot for 2016 USA Triathlon Nationals. I did the 4 x 4 routine in the four days leading up to the race. During the race I never felt any cramps or lactic acid build-up in my legs even though I had multiple surges on the bike, passing many other racers on the short climbs. On the run I set my 5k PR by close to 2 minutes in a triathlon and 1 minute over my stand alone 5k PR. Even as I found that final gear in the sprint to the finish my legs never seized on me nor even felt close to it. I will be using this product again and again for my "A" races. Highly recommend!

More Unicorn magic in a pill!I've been taking this supplement consistently for a month now during my marathon training and I really do see a difference in my energy levels and reduced soreness. In fact, I haven't had any soreness for this marathon training while taking this product! I can't wait to officially complete my first marathon and that's saying a lot for someone who has Lupus! If you don't have this as a staple to your training regime, well, you're working harder, not smarter.

Nausea?I tried these for the first time before my A race triathlon. I had a great race but I'm not sure it had to do with these pills. I've only used them once so I'm undecided but while taking them I had a lot of unexplained nausea even vomited once. I'll try them again with reservation.

Like flooring the DeLorean to 88 mph!I took a big risk using "something new" before my Boston-qualifying marathon last month in CA, but it paid off big. Having trained with Hammer Gels for over a year, I knew the quality of Hammer's products. Am I glad I did--I've never felt stronger during and after any of my previous six marathons. In combination with Hammer Gels and Endurolyte capsules, I bettered my PR by almost 7 minutes, snagging my first sub-3 in 2:57. That's enough to make the old Doc say, "Great Scott!" Thanks Hammer!

great pre race supplementI have used this product consistently for triathlons, trail and road half marathons, various cycling events (mountain and road) and have found it to be extremely helpful. I know I performed better with this product and felt strong at the finish, hit PRs and got back to training right after racing with no problems. I gave this product 4 stars on because if I do the full course as described (up to 8 capsules a day for 4 days) I get a mild headache for the last two days or so. If I half the dose (so 4 capsules a day for 4 days) I feel that I still get the same benefit but without the headache. I believe this product has helped me race that much better that I'm wiling to tolerate a mild headache. I have never experienced nausea or vomited, just a mild headache. In combination with other Hammer fuels and supplements I have great results with this product.

awesome results!!I tired this before i did LOTOJA (206 mile road race), used directions as indicated and felt incredible the whole day. I've always had issues with bonking and cramping but not on this day, with 20 miles left in the race - i decided to "red line it" to the finish and had plenty left in the tank. Felt great the next day as well. I will for sure go with this product again on future endurance races.

For My "A" RacesI have been using Race Day Boost for 2 years now. I take the loading dose before every important race and my "A" races! As a cyclist I need any extra advantage in performance when it comes to beating my competitors or the clock.
