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. Tailwind Lets Me Go the Distance 5 Star Review

    (Submitted on 11th Feb 2016)

    I've trained with Tailwind for over a year now and still haven't got sick of the flavors or had stomach issues. I've ran with it in my hydration vest for distances up to 50 miles, supplementing with aid station food along the way. It will be with me as I tackle my first 100 miler this Fall.

  2. Best endurance fuel by far 5 Star Review

    (Submitted on 9th Feb 2016)

    I was recently diagnosed with hypoglycemia and have been searching for an endurance hydration fuel that doesn't have fake sugars that alter my blood sugar level. Tailwind had exceeded these standards and helps me go longer without any sugary crash. Love it and continuously recommend it to fellow runners and yogies.

  3. Simple and Complete 5 Star Review

    (Submitted on 8th Feb 2016)

    Great, fantastic and easy. Love using this for those long bike rides to mix it up from just water. Tastes way better than other sports drinks I've tried and doesn't make me feel sick (like some brands have in the past). Used for long races on the bike, I wouldn't go any other way!

  4. Best Endurance Fule 5 Star Review

    (Submitted on 3rd Feb 2016)

    Best fuel I have ever used....ran 100 miles without stomach upset and with minimal fatigue.

  5. No cramping or bonking 5 Star Review

    (Submitted on 2nd Feb 2016)

    I used Tailwind for my first 12 hour solo MTB race this past weekend. Been using it for training for two months. Had three bottles of TW on me for the first lap, and just tossed the empty at each lap pit stop (10 mile, 1,100 foot laps). Grabbed three more at lap four... and so on. Never cramped. Never bonked. Took second in my age group. Never close to cramping or bonking. Amazing product.

  6. Works great! 5 Star Review

    (Submitted on 2nd Feb 2016)

    Love the product and how I don't rely on sport gels to get me through long runs.

  7. Always on top 5 Star Review

    (Submitted on 30th Jan 2016)

    Tailwind works all day, every day, any time you need endurance nutrition. No reason to try anything else.

  8. has been great for 20+ mile runs 5 Star Review

    (Submitted on 26th Jan 2016)

    This is by far the best sports drink product that I've used for long runs. I have had a pretty sensitive stomach for any runs over 4 hours, and tailwind has helped that immensely. Personally, I like to supplement it with food just to have something in my stomach.

    My personal method - I've done this the past 3 weekends on my long runs (above 20 miles and around 4 hours) - I bought a large bag of unflavored, then a few caffeine and lemon flavor. I find a nice mix (I don't want a lot of caffeine, rather a consistent low dose) - usually 1 scoop of unflavored, 1.5 of a different flavor or caffeine. I mix this with about 750 ml of water - any less, and it's too sweet for my taste. 750 ml has been the magic spot (there are great 750 ml soft flask that fit great in my salomon vest).

    I go through one of these - about 250 calories - every hour. I supplement this with a bit of food just to have something solid in my stomach - personally, a 200 calorie package of cliff blocks is enough (there's around 8 in there so just eat one periodically). I haven't had any issues overloading my stomach OR feeling like I need more calories. It's been about spot on!

    The unflavored has a nice taste to it, I also liked the lemon, berry and orange. I was mixing 2-2.5 scoops with only 500 ml at first and it was definitely too sweet for me.

    I'm hoping it will really pay dividends in a few upcoming ultras!

  9. Simple. Easy. Complete. 5 Star Review

    (Submitted on 26th Jan 2016)

    This is all that you need to be awesome on your run. Aught as you pass the lines to the porta johns because you won't have a gut bomb. When I run with Tailwind I know I will have enough energy to perform at my best. I'm not an elite runner, nor am I being paid to say this, it just works for me!!!

  10. Solid as always. 5 Star Review

    (Submitted on 25th Jan 2016)

    I've been using Tailwind for a year and half now and it has been my primary (90%) choice for nutrition in training and races. In that time I've completed 10-15 races of marathon length or longer and TW has kept me going throughout.

    Great customer service adds to the TW experience. Excited to try the new flavors coming out

  11. two thumbs up 5 Star Review

    (Submitted on 25th Jan 2016)

    a 12 oz glass of water with Tailwind eliminated the muscle burn on my daily 4 mile bike sprint to work each morning without coming back up on along the way.

    Its also great in the camel pack during those longer weekend rides into the mountains.

  12. It just works 5 Star Review

    (Submitted on 22nd Jan 2016)

    I'm continually amazed at just how Tailwind just works. Mile by mile I wait for that feeling so often found using other fuel options. Tailwind just doesn't fail to give me what I need for long runs.

  13. Ah-mazing 5 Star Review

    (Submitted on 22nd Jan 2016)

    I have struggled with fueling my long runs. When I decided to train for my first full marathon I asked friends what do you do? Kim, who ran the Flying Pig 3 -Way with me in 2015 recommended Tailwind and sent me a sample. OMG. this is amazing. Longest run so far is 18 miles and I had enough left in my 20 oz bottle that I believe I may only need 20 oz for the FULL!! I am not starving after the run and the next day I am walking like a normal person not hobbling like I ran 18 miles.

    [Tailwind response]: Hi Colleen, we are so happy that Tailwind is working for you! One thing to keep in mind, however, is that you'll probably need more than 20oz of water for a full marathon. In general, we recommend about 200 calories/20oz of water/hour. Everyone is different, so please feel free to reach out to us at supportcrew@tailwindnutrition.com with any questions! Thanks!

  14. I'm in love! 5 Star Review

    (Submitted on 21st Jan 2016)

    I've dealt w/ 'gut' issues on multiple marathons and when I bumped up to the 50K distance in October, my stomach shut down. I couldn't take in any nutrition -- even real food exacerbated my nausea. An ultra-distance friend of mine suggested TW so I ordered it b/c I am running another 50K in March. I took it out on a 15 mile training run and felt PERFECTLY fine the whole run. I never bottomed out w/ my energy and I never felt nauseated. Towards the end of my run, I just felt hungry...but it was time for breakfast ;-) I've used it a few more times since that first and have had the same miraculous results. I LOVE this product and will use it on all my long runs and racing events. It's such a relief not to have to worry about GI troubles!!

  15. Fantastic Product and Support 5 Star Review

    (Submitted on 20th Jan 2016)

    I have been using this product for years. At age 71 and still doing ultra rides, I MUST have constant and dependable replenishment. This is the only product that has done this for me. Additionally, I have a friend who rode No Country for Old Men, in the Big Bend of Texas and this company provided product support to him. Now That is a company I will do business with again and again.

  16. Does what it claims, provides excellent nutrition! 5 Star Review

    (Submitted on 20th Jan 2016)

    Having tried many different nutritional products for long runs and Ultras I've been really impressed with Tailwind.

    Like many, I usually find that after a while my stomach is sore from all the gels or other name brand energy mixes that I have tried. I have tried a lot over time.

    This truly has been the most comfortable and I have no problem drinking it as time goes on unlike other products.

    I have reduced my electrolyte pills and other gels with the use of Tailwind and have more energy and endurance. I do still have some gels to top this off.

  17. Best endurance liquid nutrition! 5 Star Review

    (Submitted on 19th Jan 2016)

    Just found Tailwind and so far I love the taste, easy to mix powder and easy on the stomach formula. Have been using it for my long runs and love it.

  18. Works Great/Taste good 5 Star Review

    (Submitted on 19th Jan 2016)

    For me, Tailwind prevents late ride bonking and sits well in the stomach. I like being able to get all the calories and electrolytes I need just through my water bottle. In hilly bicycle races I've been frustrated trying to gag down a bar while climbing with a heart rate of 170, or trying to fish in my jersey pocket while negotiating a high speed descent. Tailwind taste good and is easy to use, great for long rides!

  19. Full 3 Star Review

    (Submitted on 17th Jan 2016)

    I really wanted to feel the energy effects of this product. It could have been just me yesterday during my race or I need to tweak the portions. I felt full, which is a good thing. It'll keep me full during my 50k in two weeks. I didn't need to stop at the aid stations during my half, which was nice. No stomach issues!! That's a major plus.

    [Tailwind Response]: Thanks for your feedback! You might not have felt the “energy effects” from Tailwind due to the fact that by sipping your fuel you are metering the intake of your calories. By taking in your calories over the course of an hour (as opposed to a gel or chew which hits your system all at once) you eliminate the surges/highs – but also avoid the valleys/lows. Instead, you have steady energy throughout the course of your run.

  20. Bought small packets before and came back for more.. 5 Star Review

    (Submitted on 13th Jan 2016)

    I used the 200cals packets before during my first marathon, it worked very well. I have a nervous stomach and some gels dont work with me. Recently, out of a whim, i followed a friend for a 50k (training run) and I carried 400cals of Tailwind. It worked well during the first 20miles, after which I was using Larabars. I can feel the difference in energy between the two fuels. No, this is not the first time I have used Larabars on a long run, the bar is harder to be metabolized. I dont usually fuel for 2-3hrs run, anything longer, Tailwind is perfect.

  21. Great find... 4 Star Review

    (Submitted on 12th Jan 2016)

    I gave just 4 stars cause I started using Tailwind this fall and have only had the opportunity to use it through one race training cycle.... but so far it's great! I principally use Tailwind for trail running because it has NO adverse affects on my stomach... Simplified my nutrition for 20 mile trail runs, using little else besides tailwind. Plan to overhaul my triathlon nutrition with tailwind in 2016.... Easy to mix, easy to cleanup, great taste. Another couple training cycles and I am sure I will give it 5 stars.

  22. Awesome! 5 Star Review

    (Submitted on 12th Jan 2016)

    I would not use any other fuel than Tailwind. I have Ulcerative Colitis and cannot have fake sugars that are found in other fuel chews and powders. My system just cannot take them. So I have been using Gatorade and Gu Chomps. Then I found Tailwind. And have not looked back. It supports my fueling needs so I am never left with that hungry "chew your leg off" feeling at the end of a race or workout. I also do not have the gut bombs I have had off and on with other fuels. LOVE THIS STUFF.

  23. Great tasting and great results 5 Star Review

    (Submitted on 11th Jan 2016)

    The Endirance Fuel is great for running, biking or swim. I've gone through a bag and it's amazing. No cramping or bonking. It tastes good but it's not so powerful that it turns you away from wanting to drink.
    Recommend heavily!

  24. Tart and delicious 5 Star Review

    (Submitted on 4th Jan 2016)

    First test run and won't need to try anything else, until I feel the need for some berry buzz. It's so good, I almost crave it.

    Any ideas on the best way for me to re-package for races in bottle size doses?

  25. tastes good, feels good 5 Star Review

    (Submitted on 3rd Jan 2016)

    Don't resign yourself to having a "bad" or "sensitive" gut until you try tailwind. It's easy to use, tastes good even after hours of use, and unlike everything else I've tried, doesn't make me sick.
