Tailwind Endurance Fuel


Description and Reviews

All you need, all day. Really.

Tailwind mixes with water to meet all your calorie, hydration, and electrolyte needs, without upsetting your stomach or making your taste buds revolt. Just toss it in a bottle or hydration pack, shake, and GO!

Supplemental Facts
  • Complete calories, electrolytes, and hydration: Ditch the gels, chews, and pills, and go all day with just Tailwind.
  • No gut bombs: Stomach problems? You’ll love Tailwind. Unless you enjoy being doubled over, retching.
  • Tasty all day: Clean, light flavors taste better the longer you go.
  • Hydration pack love: Dissolves on contact with water and cleans up with a quick rinse. No film, aftertaste or science experiments!
  • All natural: Crystal clear with no dyes, preservatives or 4-syllable magical ingredients.


Each serving is 100 calories. For endurance workouts, mix 2-3 scoops per 24 oz of water per hour. Adjust to your personal calorie needs during training, using hunger as a guide. When it’s dialed in, you’ll feel satisfied and energetic, not hungry or full. On hot days, keep the same calories per hour, but increase water. To use in combo with other foods, reduce Tailwind intake by the calories you’re consuming elsewhere to avoid overloading the gut. For shorter workouts (<2hr), you can use less Tailwind to taste.

  1. Cyclist's best friend

    Posted by Trevor on 11th Aug 2014

    Had my target race for the third straight year this weekend - century rides on consecutive days. This was the first time using Tailwind for the race, and it was a world of difference. Energy levels never flagged, the heat was no big deal, and I felt great. It led to my best times by far. I am built not at all like a prototypical cyclist, but I felt like I was ready for the Tour. Great product! Next year my plans are far more ambitious, and Tailwind will definitely be along for the ride.

  2. Better than the rest

    Posted by Scot on 11th Aug 2014

    I'm an experience marathoner, Boston qualifier, and burgeoning ultra runner. I also ride road and mountain bikes. That said, I've tried everything from gels, gummies, fizzies, to every thing in between. I've learned a lot about race nutrition through all of these product trials and nothing approaches Tailwind for consistently providing me with "non-gagging" calories and hydration. On my longer mountain runs I still incorporate nut butters and a few other caloric augmenters but Tailwind provides the base. Thanks for making a great product!

  3. love it!

    Posted by jenn on 10th Aug 2014

    great flavor, no stomach upset. no chalky texture like most other brands.

  4. Just the one I like

    Posted by Ignasi on 10th Aug 2014

    I have been using this one for months, and not thinking of changing :)

  5. It really works!

    Posted by Unknown on 5th Aug 2014

    Ran a 2.5hr run after running over 50miles earlier in the week. I used Tailwind throughout my run in which I normally would have consumed at least two gels. Even though the weather was hot and humid the 2-Bottles of Tailwind I used seemed to be more than enough to ensure I had the appropriate nutrients my body needed. At the end of the run I had no loss in speed and no decrease in energy. I'm looking forward to using it on my 12hr-ATR in a month.

  6. GI Issues Solved!

    Posted by Tim on 4th Aug 2014

    I am an Ultra Runner who has tried everything under the sun to deal with GI Distress during endurance events. For years I would have GI Issues pop up (not every race/training) unexpectedly and randomly. Despite all the nutrition advice I followed, it continued to happen.

    I have now used Tailwind exclusively for any training or race over3 hours and for the last 6 months not one single GI Issue.

    Love it.

  7. This Fuel Ain't No Fool

    Posted by Chris on 3rd Aug 2014

    I'm an active individual who has been inspired toward endurance athletics. Having hypoglycemia, I need to be cautious about my carb intake and not under- or over-do it. After numerous negative experiences with other fuels I wasn't sure if I could extend my efforts past the half marathon distance. After attending the Vermont 100, I modeled some of the athletes there and tried Tailwind. What a difference! Now I feel comfortable running 25k+ and am considering my first 50k. Thanks Tailwind for putting together a great product!

  8. Works as promised

    Posted by Joe on 31st Jul 2014

    I've used Tailwind Endurance fuel for a few MTB rides and have not had any negative issues with it. The taste isn't overwhelming, my stomach doesn't blow up when I use it, and it gives me energy late in my rides.

    I will purchase it again.

  9. Worked great for energy

    Posted by Stuart on 29th Jul 2014

    I decided to try Tailwind after reading some reviews online while doing research for something to help me complete a 70 mile mountain bike enduro race this summer. I started using it early in the season while building my endurance for the race. I love the taste and it did help increase energy levels. I felt I could ride longer and faster when using this product versus water only.
    It was easy to take with me in the race as well. I felt really good for about half the race but ended up with some wicked thigh cramps a little over half way through. I tried to drink 28+oz every hour but lost track most of the time. I was able to finish the 70miles but it was tough going. Not sure if it was my conditioning or hydration that led to the cramps. Maybe you could give me some advice to avoid this in the future.
    I like the product and will continue to use it for basic training and any other events that come along.

    [Tailwind Response]: Hi Stuart, thanks for your feedback. Cramping has a variety of causes, and scientists aren't even certain exactly why and how they occur. Electrolytes play a role, but so does hydration, fuel availability, fatigue (both general and muscle-specific), body
    temperature, blood flow and waste removal rates, neurological firing, muscular range of motion, genetic makeup, and other factors. It's hard to pin the cause on one specific factor, and it varies by individual. If you are a really heavy sweater, you might try adding more electrolytes, but that is probably oversimplifying, and to be honest if the source of your cramping was electrolytes, then Tailwind should have addressed that variable. Feel free to email us at info@tailwindnutrition.com with more info and we'll try to figure out the root cause. Thanks.

  10. Great taste - good nutrition

    Posted by Unknown on 29th Jul 2014

    I started drinking Tailwind while road riding because of the nutrition value, light flavor and no stomach upset. Won't use anything else now! I take it running and mountain bike riding as well as on hikes. Have recommended it to my friends!

  11. Easy nutrition on the go!

    Posted by Chuck on 29th Jul 2014

    Heading into my first 12 hour race I was looking to improve my nutrition. I would occasionally have problems with GU and I wanted to simplify everything. During my last marathon I had problems scheduling my GU and salt tabs and frankly just forgot on more than one occasion.

    I trained with Tailwind over the last few months and everything just worked. I didn't have to carry gels and tabs, just drink every 10 minutes. My energy was stable and I kept going strong.

    I had a great 50 mile race this past weekend and I can't even fathom how many GUs I would have eaten over the coarse of 12 hours. Tailwind just worked.

  12. Training for half ironman

    Posted by Marianne Van Houtte on 28th Jul 2014

    Still in the review process. I did a 35 mile bike ride with an 8 mile run after in 90 degree humid weather. Energy on bike was great but I did have trouble on the run. I was extremely thirsty for plain water. I mixed 2 scoops per 24 ounces for bike ride and finished 2 bottles. Then 1 scoop for 16 ounces of water for the run. I ended up walking/ running for several miles. My fingers were pretty swollen also. I think I will try hydrating more day before brick and adding some plain water in between. Recovery has been good. I really think the heat and humidity were a little too much. Did not use any gels, no stomach issues at all, just wished for a little more energy on the run.

  13. Absolutely love, love, love this product.

    Posted by Jeremy Hanson on 28th Jul 2014

    I've tried EVERYTHING to fuel my runs, and running long distances in Houston during the Summertime, it is incredibly important to find something that you can drink a lot of that actually works. It is very easy to drink Tailwind for an entire long run without getting tired of it, and I've found that I need fewer gels to help fuel the run too. I have a 50K, 50 miler, and my first 100 miler coming up soon and Tailwind gives me a lot more confidence going into them. I know my body can do the distances as long as it is hydrated and fueled properly. I'm definitely a fan.

  14. Nothing better !

    Posted by Bill Packard on 27th Jul 2014

    I have been using Tailwind for 1.5 years now. My training and racing has improved constantly mainly due to the use of Tailwind. It allows me to go ultra distances at a fast pace and not have to worry about running out of fuel or getting sick to my stomach. If Tailwind works so well for me at an average of 600 miles per week in the Arizona heat, it should be the best product for just about anyone !

  15. My sensitive stomach is happy.

    Posted by Josh on 25th Jul 2014

    So far Tailwind has been easier on my stomach than any product I've tried. Still dialing dosage to exertion ratio but have been quite satisfied so far. Have tried all flavors and all are very palatable. That being said drinking any flavor for 3-4+ hours on a hot day gets a little old. May try higher concentration in one bottle and plain water in another.

    Nice to have a product perform as advertised, thanks Tailwind.

  16. Good Tailwind helps Badwater

    Posted by Steve Maliszewski on 25th Jul 2014

    Ran Badwater using tailwind as the basis for my nutrition. It worked really well. I didnt have any major stomach issues and was able to still be alert and running strong in the later miles of the race.

    Thanks guys

  17. Seriously works!

    Posted by Unknown on 24th Jul 2014

    I love this product, because it has a mild, pleasant flavor and it seems to work well. I have not experienced any bonk or stomach issues using this product. While my friends were gagging down pack after pack of gu on a recent 20+ run, I was sipping the Tailwind and loving life!! I've tried other (more expensive) products that make similar claims, but Tailwind is the only electrolyte powder that actually comes through on its promise.

  18. 100 miles, again

    Posted by Zak on 23rd Jul 2014

    Just in case I had any doubts.....ran the Vermont 100 using only Tailwind again. Fantastic results; no dips in energy, switched to the caffinated TW after 9 PM and felt a charge of energy that lasted until the finish. Easy recovery again! Improved my finish time by 1:45!

  19. Not done testing

    Posted by Jim McGuckin on 22nd Jul 2014

    I have a 50K in two weeks in which I will really get to put it to the test. So far the flavor has been pleasant on long runs and digestion seems to be no issue but we will wait to see after race conditions and 50K.

  20. Better, faster, stronger

    Posted by reuben on 21st Jul 2014

    I took a leap of faith and put tailwind to a first test this past weekend for my first half ironman. I'm a bigger person who struggles to stay hydrated and keep my salts/electrolytes in check. I constantly finish longer endurance events cramping or completely wiped. I sucked down three 24 oz 2-scoopers on the bike and an additional bottle of water. felt very strong coming out of T2, stronger than I've ever felt. No stomach issues (another issue I battle), and a very powerful run. I'm a believer! It's hard to think about using anything else for nutrition and hydration.

  21. Great even when mixed with Mandarin Orange

    Posted by Elena on 21st Jul 2014

    Felt great with an 18 mile run, no dips in energy. Did not use anything else for fuel. Accidentally mixed it with Mandarin Orange and tasted great!

  22. Reaching New levels

    Posted by Mike MacKay on 19th Jul 2014

    I had tried Tailwinds before and I thought it was good but there are so many different options out there and I went and tried a few.I had only been doing sprint triathlons and always cramped up on the run,This year I jumped up to olympic triathlons and doubled my training.I still had some tailwinds and started using it only.What a difference.I not only finished under my goal of 3 hours, there was no cramping!!Thanks tailwinds I learned my lesson, stick with the best.

  23. This #*!* works!!!!

    Posted by Gary on 18th Jul 2014

    I go on training rides that vary in length from 30 to 50+ miles, four to five days a week. Using Tailwind I no longer have to stop to eat power bars etc. Makes it so much easier to prepare for the next days ride. I just fill my Camel back with TW, place in the fridge and am ready to go for my ride the next day. I don't feel hungry during the ride, especially towards the end, like I used to when downing power bars or whatever I happened to take for my ride prior to using TW. I definitely will be using this as my go to fuel for my longer rides from now on....

  24. No stomach issues = 1st in Age Group at Black Hills 100!

    Posted by Ed Thomas on 16th Jul 2014

    I started using Tailwind a couple of months ago. I used it in training and used it at the Kettle Moraine 100 where I paced a friend. Even though I was pacing and not racing I felt good throughout the evening and late night hours and never felt hungry at all. I was pleased with the results. This past weekend was the true test. I ran the Black Hills 100 in Sturgis South Dakota. I carry 2 handhelds and loaded them with 250 calories each. I pre-made several baggies filled with Tailwind (250 calories ea. for the outbound and 200 calories ea for the inbound) and kept two in the pockets of my handhelds and the rest in drop bags. I worked hard at not exceeding 300 calories an hour and don't think I ever crossed that threshold. So here's the scoop (no pun intended!..ha!), the Tailwind worked like a dream! Last year at Leadville I had stomach issues the last 24 miles and couldn't keep anything down. Nothing, not even water. At Superior stomach issues weren't as bad but not much of an appetite and not much energy. I finished Leadville in 28:36 and finished Superior in 36:30. This past weekend, using almost exclusively Tailwind Nutrition (Berry flavor on the outbound, Raspberry Buzz on the inbound) I finished in 23:59. This was good enough for 6th place overall and 1st in my age group (50-59). Besides the Tailwind I ate 8 potato chips(yes I counted them for calories sake),7 pieces of watermelon and one piece of pineapple (because it looked so good). Other than that, only Tailwind! No stomach issues, no lack of energy. I just sipped one 20 ounce bottle per hour to keep my calories up. During the overnight hours I dropped down a bit on consumption because I wasn't sweating as much. Whenever I got a bit hungry I just took an extra sip and I was good. Also, this is the first race where I did not consume any protein whatsoever. I think this helped with carbohydrate absorption and glycogen conversion (but what do I know, I'm not a scientist!...lol) I will be running Leadville in August and couldn't be happier! I have FINALLY found the nutrition product that I have so desperately been searching for. I know a lot can happen in a 100 mile race and things don't always go as planned, but as far as nutrition and hydration and electrolyte replacement I'm golden! When you run that far the less you have to worry about the better off you are!! Thank you so much Tailwind! Love you guys!!

  25. Happy Gut!

    Posted by Rebecca on 14th Jul 2014

    I have tried several hydration and fueling products before stumbling across Tailwind at a local trail race. Since then, it is the only product I use and have recommended it to everyone that will listen. My stomach is sensitive and Tailwind does not make it hurt like the gels do and it tastes sooooo much better. I have even given it to my child when she had a stomach bug and she bounced back in no time. Thanks for a great product!
