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. Awesome!

    Posted by Unknown on 19th Aug 2014

    I've had so much trouble with my stomach when running long and because of that I was poorly fueled for my first marathon by the end. With this product I can take in a little bit of nutrition and electrolytes with each sip so my stomach never gets overwhelmed and I can easily adjust the amount I take with me depending on my distance! I love it! Thank you!

  2. Best.Hydration.Product.Ever

    Posted by Thaddeus Meyer on 18th Aug 2014

    Thank you, thank you, thank you for coming out with the best hydration product I've ever had. For several years I've had to eschew the usual sports drinks for water and salt pills because they were either too sweet, too grainy when mixed, left too much of an aftertaste, or caused too much GI distress. Or if I was lucky enough to find one that I could stomach long enough for a 100 miler, I was so sick of it by the end that the mere thought would make my stomach turn. With Tailwind, however, that all changed. I haven't tested it out for any 100s yet, but I've logged plenty of time on my legs in this sweltering summer and have been nothing short of amazed. I've been able to ditch the salt pills and can take in plenty of easily digestible calories for sustained efforts. I'm never left with a sickening aftertaste, and drinking it doesn't make me want to reach for the water as with other sports drinks. What's more, Tailwind doesn't sit like a log in my stomach, and I have yet to experience any nausea or the dreaded hydration bloat/slosh. Can't wait to try the other flavors...even the unflavored version tastes great!

  3. This product does exactly what it says it will do

    Posted by Marchant Wentworth on 18th Aug 2014

    Tailwind eliminates the need for carrying a lot of messy bars and gels and never produces gastic upset. I feel that the use of Tailwind has eliminated the threat of the dreaded "bonk" and its use has improved my rides.

  4. Solved my nutrition problems

    Posted by Derek L. on 18th Aug 2014

    I have been waiting a while to write this review, because I thought for sure it was a fluke the first time after using it. After several uses, however, I have determined that it is indeed the tailwind that is responsible for my increased longevity on the trails.

    I recently got into running. I was 210 pounds, and lucky enough to have a lifelong friend who turned me onto this. He used it exclusively to run a sub 25 Leadville 100, but that is another story.

    I was stuck with 12 minute splits when I first got into running distances over 10 miles. The very first run I did with tailwind, I increased my mileage by 20% and my splits dropped over 1.5 minutes. I was pretty sore after, but I did it.

    Since then I have used tailwind on every long run since then except one. The long run that I did not use tailwind, I only made it a half marathon distance and my splits were back in the 12's from the 10's.

    I would recommend that any new runner try this as a nutrition option. Based on the guy who turned me onto it, experienced runners won't do to bad either. He only ate a cup of broth and some grapes at Hope 2 and Twin on the Leadville 100 run, and he used tailwind only for the rest of the race.

  5. Tailwind fuels my 100 and gets me to the end!

    Posted by Scott Gaitten on 14th Aug 2014

    I had been training for my first 100 miler over the last 5 months. I had a friend tell me about your product, and give me some to sample on my next long trail run. I tried the product and it seemed to work fine. No stomach issues, no mid run loss of energy. But, you never really know how the product will do until you get into an event that takes 20+ hours. I ran my first 100 miler on Aug 2nd/3rd, and I was extremely happy with how the product held up. Lot's of issues with those around me, nausea, loss of energy/focus. But my race went as well as could be expected, and the product held up well all day. I finished the BR100 in just under 25 hours. I'll be back to do another, and I'll be using your product the whole time. A couple of suggestion ... if possible ... create tablets that dissolve in water, they would be easier to transport/handle during the race ... and create "light" flavors ... the flavor I had started getting a little too sweet half way through the 100. I have a buddy that purchases your flavored and non-flavored products and mixes them 50/50 to lighten them up. Thanks again for creating a great product. I'm spreading the word in my local running groups.

    [Tailwind Response]: Scott, thanks for your feedback! We have looked at putting Tailwind on a tablet, but the problem is the size of the tablet that would be required to hold 200-300 calories. Great idea though, and please keep them coming!

    I love Tailwind! Wish I would have had it before. Use it on all of my longer runs and don't need any gels or anything else.

  7. Tailwind Nutrition Tag Line Tells you All You Need to Know!

    Posted by Greg Dingey on 13th Aug 2014

    It's really as simple as " All you need, all day.Really". I purchased Tailwind Nutrition Endurance Fuel ( Lemon) and used it for the first time on a 24 mile trail training run in preparation for my first 50K. I felt great during the entire duration of my run,no need for any gels! What really impressed me about the company is how they personalized my order.They included my name on the bag weaved into a motivational message and sent with my product a handwritten note, thanking me for trying their product and asking for my opinion on it. Well Danielle, your product simple rocks! Can not wait to use it on race day!

  8. Great Stuff!

    Posted by Rob Groome on 12th Aug 2014

    This stuff is great. Used it for a few hard workouts and I felt great both during and after them. The flavor is subtle and not sugary or sweet. Highly recommended.

  9. First race with only Tailwind, 1st place!

    Posted by Adam P on 12th Aug 2014

    I got first place in my first 4 hour mountain bike race in 100+ degree Texas heat! I don't do well in the heat to begin with, so I didn't expect to place well, but I decided to just run Tailwind only and no edibles during the race and see what happened. Ended up getting first place and ZERO gut issues and ZERO camps whatsoever!

    I AM A BIG FAN!!!!!!!!!!!!!!!

  10. Absolutely Remarkable!

    Posted by Jose on 11th Aug 2014

    I can't say enough about how wonderful TailWind has been. The product is amazing and the customer service goes far beyond any expectation you can have from a company. Oh yeah, and Tail Wind works! I used it exclusively at a 50M Run and I haven't looked back!

    Great stuff guys & gals!

  11. Tailwind Mandarin Orange

    Posted by Robert Riesenberger on 11th Aug 2014

    I used this for the LT100 Mtb Race last year along with Hammer Perpetuem. This year I solely used Tailwind and and like you guys say"It's all you need ,all day". I trained with it for months and before the race and can't say enough about this product. AWESOME !

  12. Never disappointed!

    Posted by Scott Johnson on 11th Aug 2014

    Always happy with the taste, and even more happy with the results when I use Tailwind. And the bonus goodies they throw in with the order doesn't hurt!

  13. 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.

  14. 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!

  15. love it!

    Posted by jenn on 10th Aug 2014

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

  16. 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 :)

  17. 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.

  18. 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.

  19. 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!

  20. 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.

  21. 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.

  22. 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!

  23. 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.

  24. 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.

  25. 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.
