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. I'm a believer.

    Posted by Adam A. on 25th Jun 2014

    Bought some Tailwind (naked and lemon) on recommendations from a few endurance athletes far more experienced than me. Tested it out on a few runs and bike rides leading up to the Bighorn 50k. Used it as my sole fuel and hydration and it carried me to a 13th place 5:35 finish. No energy crashes, no stomach issues, and still easy to drink til the very end. Super fast shipping even with a handwritten thank you and request for feedback. I think I've found my go-to fuel for any future endurance endeavors.

  2. Does what it says.

    Posted by Randy A on 25th Jun 2014

    Like some others, I was a little skeptical of some of the claims for Tailwind Fuels. But after reading so many positive reviews, I decided to give it a try.

    I started using it back in March, first for rides up to 2 to 3 hrs. It worked very well and I didn't feel any need for gels or other energy products. After winter *finally* broke in early May here in MI (hint: sarcasm), I started doing longer 4-8hr rides. Following the mixing instructions, I found that the Tailwind fuel really did do exactly as it claimed. Even for those longer distances/times, I really didn't feel the need for other fuels. I will admit though, after about 4.5 to 5hrs, my body will start wanting some real food. But I've found that those cravings for sugars and salts weren't as intense as before. And even my general hunger after riding wasn't as big as before using Tailwind fuel.

    So all-in-all, I am happy with Tailwind Fuel. On my second order I'm going to try out the caffeinated fuel. Mostly for a little extra kick, but also to see how the fuel works in conjunction with the caffeine with my body.

    Great product!

  3. Awesome so far

    Posted by Ron on 19th Jun 2014

    I have only used tailwind on three bike rides so far,but can honestly say it does what they say it does. I have no hunger even after a long ride. I noticed that I don't feel the need to destroy our refrigerator when I get home. Thanks for making such a great product.

  4. Packageing

    Posted by Robin Willard on 19th Jun 2014

    I hope you are not thinking of discontinuing the small sealable pouches in favor of those silly tubes. The pouches are so convenient for traveling to events Robin

    [Tailwind Response]: Hi Robin, thanks for your feedback. The stickpacks are brand new and for now are replacing the 4 serving pouches. We are always listening to our customers, and the vast majority wanted the convenience of the stickpacks. But, we'll continue to monitor what are customers say...

  5. Tailwind, you complete me.

    Posted by ANTHONY DORCH on 17th Jun 2014

    For the past 2 yrs ive been improving my running technique/form. Now ive strengthened my frame to support my running. I have all the gear and toys needed to compliment ultrarunning. The final piece to the puzzle was my running nutrition and Tailwind delivered. No more gels at this hour, salt tabs at this hour and how much to drink in between. Now, I can just enjoy the trails and run. Adjust fluid intake as weather dictates and that it. You guys "ROCK". Thanks Danielle for the thank you card. When I get the chance, I will order the tech shirt.

  6. Great product!

    Posted by Debbie on 17th Jun 2014

    I used Tailwind for my first Ultra last Saturday. It didn't make my stomach upset and I had enough energy to finish 31 miles. I supplemented with 2 natural gels only because I was a little hungry.. I am very happy with the berry flavor and I have been using it all spring and summer for my trail runs.

  7. Great fuel for the trail

    Posted by S Snow on 17th Jun 2014

    This is an outstanding way to stay fueled and hydrated on trail runs. I have gone through a 50 serving bag of Berry and will definitely be ordering more! Tastes great and is easy on the gut. 2 scoops in 24 oz worked for me. I usually get quite hungry feeling after a couple hours but Tailwind truly kept me feeling good for efforts up to 4 hours. Haven't tried it on any runs longer than that yet but I am looking forward to doing so soon! As others have noted, great product and great service!

  8. great stuff

    Posted by Unknown on 16th Jun 2014

    i love the product but your package fill is horrible! the little pieces of paper went every where when i opened the box. i am still finding them a week later. i work for two startup companies and understand about saving money, but please get new packaging! great product and will continue to order.

  9. Amazing!!!

    Posted by John on 15th Jun 2014

    I purchased a package of Tailwind to use during a very hot all night 50 miler. I was trying it for the first time (not usually recommended) but I wanted to really try it out. I generally eat a lot during ultras, and did not see how fluid would be able to keep hunger at bay, but I took in 2 scoops per hour and not only did I not feel hungry, I had an incredibly consistent level of energy. My splits were incredibly consistent, and on a very challenging course I ran my second fastest 50 mile time. It was great not having to worry about salt pills, gels etc. Tailwinds tastes great, caused no stomach problems and helped me push myself harder than I thought possible.

  10. it works

    Posted by mr x on 13th Jun 2014

    just got done with a 100k gravel ride in new Hampshire and the stuff works no gels ,no chews,no pills simply awesome!!!!

  11. Uncomplicates my life

    Posted by Joe on 13th Jun 2014

    I'm nearly finished with my second large pouch of Tailwind (along with several 4 serving pouches) and feel I can write an informed review.
    By my nature, I had obsessed about hydration and nutrition on runs and during races. I used various foods and sports drinks and couldn't find the combination that kept me in the "sweet spot".

    I heard about Tailwind Nutrition while listening to Trail Runner Nation podcasts and thought I would give it a try. I purchased my first pouch of Lemon during the winter. Since I wasn't running that long then, I used it mainly for recovery. Now that spring is here and the length of my runs is increasing, I have been carrying a handheld (I don't use a bladder) with Tailwind on most of my runs.
    I have experimented with 100 calorie and 200 calorie mixes and find each works for different runs. I have a 50K in 2 weeks and I can put nutrition and hydration out of my mind; Just bring my cooler filled with premixed bottles of Tailwind and I'm good for the whole race!

  12. Simply the best

    Posted by Bill West on 10th Jun 2014

    I love this stuff. I seldom need to take a gel. The naked tailwind, I think is the best. Keep up the good work.

  13. Tailwind kept me going

    Posted by Ron on 8th Jun 2014

    I had been using tailwind on shorter rides and experimenting. Recently I put it to the test on Wasatch "Fun Ride" 25 mile. It was a single loop of a two loop Wasatch back 50. Starts with a grueling 8 mile climb followed by 17 miles of short climbs and steady down hills. It was a hot day and Tailwind was the only thing I consumed during the ride. I never bonked or felt hungary and posted my best time. -Thanks Tailwind.

  14. Tailwind - where have you been all my (running) life?

    Posted by ruth loffi on 7th Jun 2014

    After hearing all about your great products on Trail Runner Nation I decided to see what all the fuss was about. On unpacking my quickly mailed box of goodies (as a newbie I ordered the 5-pack) I was first totally impressed with the presentation of the product. I was apprehensive about my first run with Tailwind Nutrition and I chose the Raspberry Buzz. It dissolved easily into the bottled water and off I went. 14 miles later (mid 80s and v. humid) and two servings later, I still felt amazing! I feel like I've found my best running buddy in a bottle ;) You have a very happy customer here!

    If anyone reading this, is not entirely convinced, just try it one... you will not be disappointed.

    I look forward to many more Tailwind runs.

  15. My New Go To Drink

    Posted by Gary M on 6th Jun 2014

    Initially, I was quite skeptical of Tailwind's ability to satisfy both my hydration and caloric needs, but I felt it was worth the risk to find a product that could potentially eliminate my need to carry extra pills and bars on my rides. After reading some positive reviews on mtbr.com, I went ahead and ordered some organic lemon. I have been pleasantly surprised. On my typical 3-3.5 hour weekend training loop, it's all I need. I have been using the product for about 3 months, and I am so glad not to have to worry about the timing of my electrolyte supplementation on rides. Most importantly, there are no digestion issues with Tailwind, provided I keep the intake to about 2.5 scoops per hour (the recommended amount). On rides over 3 hours, I do take some other food, really for variety, but I'm not sure I need to. I have tried many specialized drinks, bars, and supplements, and for me Tailwind is the absolute winner. I really like the light taste. Very thirst quenching.

  16. Keep setting PR's

    Posted by randy on 3rd Jun 2014

    Hard to figure out but I keep setting PR's from 5K to marathon levels with Tailwind. Giving to my daughter now in soccer - her team is 23-0-1 since fall - she swears by it, too. Maybe it really works!!

  17. The Second 100 Will Be the Proof

    Posted by Eric Vouga on 30th May 2014

    I just received my second order of Tailwind Endurance fuel just in time for the Kettle Moraine 100. I re-ordered because last year I used Tailwind exclusively on my first successful 100 mile attempt and felt strong and relatively fresh the entire 25 hours it took me to finish. Having been a personal trainer for over 20 years I have learned to be extremely skeptical and nutritional products, supplements, etc and most of their amazing claims. I was no different when using Tailwind, but I was tired of carrying all this crap with me during ultras. I'm glad I tried it out. If I have the same results as I did on my last 100 mile race I will know for sure that Tailwind was the deciding factor and not my superior athletic prowess -- most of which is merely in my head.

  18. A winner out of the box

    Posted by Alberto Reyes on 29th May 2014

    I have only good things to say about tailwind, straight out of the box used it to fuel a 30mi run and it did not disappoint. Can't wait to try the other flavors.

  19. I like it ! !

    Posted by Greg on 28th May 2014

    I feel this works as advertised

  20. Tailwind does 51!

    Posted by Dede Owens on 27th May 2014

    I just finished my second ultra fueled entirely with Tailwind. I LOVE this product!! I ran the Nanny Goat 12/24/100 event this last weekend, and while hoping to do more miles, my blistered feet sold me out at 51. My feet may have failed, but my nutrition was solid as a rock with Tailwind.
    I made a gallon container up with Mandarin Tailwind before the race, filled up my hand-held, and off I went. (At one point, I had to make more, as, turns out, some of my peers also enjoyed- awesome!!) This race is a one-mile loop course, so when the 24 oz ran low, I just filled up again. (Over the course of the 8.5 hours that I ran, I think I refilled 6-7 times.)
    I never experienced nausea, swelling fingers or ankles, or even hunger. I never felt the need to take an additional S-Cap, or even to take in some salty foods from the well-stocked aid station. (Ok, I might have had some kettle chips, but only because they looked so good.)
    People are surprised when I tell them that I fueled entirely on Tailwind, but I have seen every one of them go on to try it.
    Tailwind, you have a follower for life.

  21. I was pleasantly surprised!!

    Posted by Laura Walls on 25th May 2014

    Like previous reviews - this is light tasting….not all sticky and syrupy sweet. I tested it out during a recent 2.5 hr ride with climbing and this product was all I needed. I had an extra bottle of water which I also used once in awhile but I sipped the Tailwind on a regular basis and it really did the job. I wasn't hungry or peckish and had energy throughout the ride. This product is a keeper!!

  22. Your stomach will thank you

    Posted by Rob on 24th May 2014

    I've tried many different sports drinks over the past 20 years, and Tailwind has become my first choice. It has the calories and electrolytes I need, but it also tastes good and it is way easier on my stomach than any other drink I've tried. Tailwind is liquid magic.

  23. 100 Miler Action

    Posted by mayhem on 21st May 2014

    I used this for the first day of my 100 miler. I have had relentless issues with not being able to consume enough calories to keep me going on these adventures. For almost 24 hours, I could drink the Tailwind w no issues whatsoever. I felt good, body felt solid, and my head was clear. I had to stop using it because my stomach could no longer handle the fluid (so I thought) but what I needed to do was to cut the mix in half and let my stomach settle a bit with not as high a concentration of mix during the night because, well, it's the night and the temps were much cooler and the breeze kept me cool enough to warrant a cut in the concentration of the mix. Also, I had been eating real food throughout the day so I should have cut the mix once evening came. Next time, though, I will know better what to do. My crew, boyfriend, and other ultra friends were happy to see that *finally* I was able to eat ! Thank you, Tailwind, it made my 100 miler feel doable. Incidentally, it was a 1.5 hr PR on that course for me, pretty surreal still.

  24. Taste great compared to other products in the market

    Posted by John on 21st May 2014

    This was the first time using the product. Taste was good, performance appeared to be solid. I did still eat a little on the 103 mile ride but felt like the Tailwinds product help stop cramping and dehydration. Once I have more experience with the product my rating could go from a 4 to a 5.

  25. Impressive

    Posted by Benjamin on 21st May 2014

    I heard about Tailwind from the Trail Runner Nation podcast. All I can say is "Wow!" I bought it specifically for a 50-mile ultra but had the opportunity to try it out for a 50k race. I had consistent energy without any spikes or nervousness. During the 50k, except for a tiny P&J sandwich cut to the size of a business card folded in half, all my nutrition was replaced with Tailwind. I wanted the 50k race to be a training run for the upcoming 50-mile so I want to take it easy but I felt so good that not only did I PR'ed but it was on a course far more challenging with almost twice the elevation change (7600ft. of climb) as my previous record.
    Also I learned that with Tailwind, I don't need to spend the cash for gels, bars, tablets, etc. and feeling like a pack mule carrying all that stuff. All you need is Tailwind!
    Here in the Mid-Atlantic (PA) not a lot of people have heard of Tailwind. After my PR, several of my friends ordered theirs and I don't know how many others might have ordered after reading about it in my race report blog. Nevertheless, I hope to spread the word. It's too good to keep it secret!
