Race Day Boost
- Boosts performance
- Increases endurance
- Reduces lactic acid
Race Day Boost greatly enhances the performance of your body’s three energy production pathways. That means, no matter what your race pace may be—low-to-moderate intensity, higher intensity/ anaerobic, or flat-out sprint—a four-day load with Race Day Boost delivers the goods to help you meet or exceed your race day expectations. Race Day Boost superbly buffers lactic acid and dramatically improves oxygen utilization, which is why it’s no surprise that, in the most extensive research to date on Race Day Boost’s primary ingredient, study subjects enjoyed a whopping 8% improvement in performance time.
Sodium (Tribasic) Phosphate – This compound enhances the functioning of all three of the body’s ATP-producing energy systems: the short-term ATP-CP system, the medium-term lactic acid system, and the long-term oxygen/aerobic system.
A primary benefit of sodium (tribasic) phosphate is its ability to buffer blood acidity and help maintain a more ideal acid-alkaline balance by neutralizing excess hydrogen ions within the muscle cell. Effectively buffering lactic acid extends energy production within this system. This nutrient also increases 2,3-diphosphoglycerate (2,3-DPG). This compound, found in red blood cells, helps release oxygen from hemoglobin into the muscle cells. An increase in 2,3-DPG will improve the availability of oxygen to working muscles during exercise.
Malic Acid – A natural substance found in apples and other fruits. Malic acid helps balance the extreme alkalinity of Race Day Boost, thus minimizing-to-eliminating the potential for stomach distress. As an essential component of the Krebs cycle, malic acid also helps boost energy levels and is beneficial for liver health.

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 ...

I used this product prior to two events where I was familiar with and had ridden portions of the routes before. I can't say I noticed any improvement of previous times. I have better success with sodium bicarbonate mixed with beta-alanine. Disappointed.
It does work! My legs felt comfortable and pace went down from 11 to 10 for my 27 mile trail run. No issues of feeling tired or crampy. I have a little hypertension, so drink plenty of water, bananas, and less salt throughout the day..
Just a little bit of extra insurance can get you there! Keep Hammering!
This product was recommended to me by my dog's veterinarian. She regularly rides the 2-day PanMass challenge and said this is the only way to start the second day without pain / soreness. I have now used the product for several half Ironman triathlons and two full Ironman triathlons. No cramping during the events. And able to get up and walk a mile to the liquor store for a six pack of Shiner Bock the next morning. You need this.
It really helps not reach that famous wall. Although you will feel tired, exhaustion is less and lactic acid buildup also feels less. i am not as soar the next day after a half marathon.
We're so glad you can rely on Race Day Boost when you need it the most! Keep up the great work!
I used this and Energy Surge for a 3k race and shaved 30-45 seconds off my old PR!! I did the prescribed 4 day preload before the race. Highly recommend both. And Hammers customer service is the best in the business.
Use it and feel ready to kick your own butt!
Would this product and I guess any hammer nutrition be illegal to use during competition or show up in a drug test? Just want to make sure even though it says it's safe.

How far apart should you space your dosing? For example if you take them at lunch and then three times in the evening is that too close together?
- Asked by Claire
- Verified Reply - SteveFor best results, and also to minimize stomach distress potential, try to space each dose of Race Day Boost 3-4 away from each other.
I race cyclocross and we have 1 to 2 races a week. How would I use this product with multiple races a week for 4 month time frame vs usage for one big race?
- Asked by Leigh
- Verified Reply - SteveWe do not recommend the use of Race Day Boost on a weekly basis. You may (key word "may") be able to derive benefits from using it twice monthly, but that is still cutting it very close. The reasons for taking a minimum of 2 weeks off between loading doses are: 1) Without sufficient time in between loading doses, the beneficial effects will diminish, as the body build up a tolerance to the sodium phosphate in the product. 2) Every day that you do the recommended 4-day dose with Race Day Boost, you are adding 772 mg of sodium to your daily intake. That puts you at 34% of the World Health Organization's recommended daily total of 2,300 mg, which is already an amount that the overwhelming majority of people can't adhere to. Doing a loading dose with Race Day Boost on a weekly or every-other-week basis is supplying your body with too much sodium. 3) High and/or prolonged intakes of phosphate are believed to interfere with calcium absorption. Because of these three factors, we recommend saving Race Day Boost for your key races only, abstaining from using the product for a minimum of 2 weeks between loading doses, ideally 3-4 weeks.
I weigh 135. Do I follow 4 capsules four times a day for four days?
- Asked by Shari
- Verified Reply - Steve The majority of the studies of the main ingredient in Race Day Boost (RDB), sodium tribasic phosphate, showed remarkably positive, performance-enhancing results with administration of 1 gram (1000 mg) of the nutrient four times daily for four straight days. That is our dosage recommendation for most athletes. However, it is theoretically possible that lighter weight athletes may be able to achieve the same benefits using less of this nutrient. With that in mind, here are some suggested usage instructions—based on a range of body weights—which you may want to test in your training: UP TO 125 LBS. Day One: 4 capsules one time/day Day Two: 4 capsules two times/day Day Three: 4 capsules two times/day Day Four: 4 capsules three times/day 126-160 LBS. Day One: 4 capsules two times/day Day Two: 4 capsules three times/day Day Three: 4 capsules three times/day Day Four: 4 capsules four times/day 160+ LBS Day One: 4 capsules four times/day Day Two: 4 capsules four times/day Day Three: 4 capsules four times/day Day Four: 4 capsules four times/day
It says that the product must be tested in training prior to use in a race. Do you do the entire 4 days when you are testing it in training? Also how long prior should you test it? Weeks prior or days prior? If I have a marathon is testing it two weeks prior too soon or too late?
- Asked by Mike
- Verified Reply - SteveMost people do a full 4-day load while testing the product in training; however, since the real goal is to assess how your body responds to the product (it’s not really to see any performance benefits), a shorter and smaller load is just fine. I would suggest this “abbreviated” dosing as your “test” load: Day One: 4 capsules 2x/day Day Two: 4 capsules 3x/day Day Three: 4 capsules 4x/day Doing the test 2-3 weeks prior is sufficient… if you do the above-listed test load, you will be fine to do the full 4-day load prior to your marathon.
So do i nees 4 bottles for 1 race?
- Asked by Steve
- Verified Reply - SteveYou will need 1 bottle to complete the "standard" loading dose for a race. Daily dose is 16 capsules (4 capsules, 4 times per day). At the end of the 4-day load, you will have consumed 64 capsules of Race Day Boost, the amount that's in 1 bottle.
If I take some the day of the race or before, will they be any help? If the race is not very long?
- Asked by Choco
- Verified Reply - Hammer SteveIn order to receive maximum benefits from Race Day Boost it requires a 4-day loading dose, taking a specific number of capsules (based on body weight) up to 4 times a day. You may see some benefits taking 1 or 2 doses the day before the race; however, compared to a full 4-day load, the benefits will be minimal.
Are you supposed to take this the day of also, or stop the night before the event?
- Asked by Ryan
- Verified Reply - Hammer SteveOnce you have done the full four-day loading dose with Race Day Boost, there are no extra benefits to be accrued by taking the product the day of the race. So, for example, if you race on Saturday, you will load with the product Tues, Weds, Thurs, and Fri. No need to take Race Day Boost on Sat.
