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. All Endurance/No Stomach Issues

    Posted by Unknown on 10th Aug 2015

    Not only is Tailwind Mandarin Orange lightly and pleasantly flavored, but it does not upset my stomach - which virtually every single other product I have tried has done. I ran a challenging 25k race this weekend solely on Tailwind and never felt better!

  2. Truth in Advertising

    Posted by Liz on 10th Aug 2015

    This product is as Tailwind advertises.
    I've been an ultra-distance runner for 30 years, and Tailwind simplifies my nutrition during both training and racing. I still use "real food" and gels occasionally for variety, during longer runs or races, but this need has been cut by at least 75%. Since switching to Tailwind, I've had no stomach issues, and only occasionally need additional salt in hot weather, to keep my leg muscles from cramping.
    I only wish race directors here in Oregon would use Tailwind as their sport drink at aid stations. It was a relief to finally run one race which used Tailwind: San Diego 100.

  3. En Español. Tailwind es lo mejor!

    Posted by Chris on 7th Aug 2015

    Desde que uso Tailwind dejé de padecer dolores de estómago en mis largas carreras. Puedo correr por horas en climas cálidos y frios sin ningún problema estomacal.

    Son muy fácil de mezclar, los paquetes pequeños son súper para llevar a las largas carreras, los sabores están muy bien logrados.

    Además de ser unos productos geniales, el marketing que tienen es fantástico. Para aquellos que entienden a los corredores, recibir un paquete a tu nombre con una notita personalizada, es lo más!!

    Gracias Tailwind!

  4. Beat the Texas Heat with Tailwind!

    Posted by Andrew on 7th Aug 2015

    I am currently in training for the Cactus Rose 100 miler in the hill country of Texas I the early fall. All my training is during the summer heat of Texas where a cool night is in the 90's with 90-100% humidity. I started taking Tailwind in the middle of training in search of something that can replenish my needs/requirements that many other products cant. I have tried a plethora of items from the GU's, EFS, Nuun, and they have worked however not for time period/length of time tailwind can contribute. My training has been overnight or through the mid day heat of 105+ degree weather. I have felt the best clean burn, most consistent, and mostly NO GI ISSUES!!! What a great product and easy to hold down. I have used all the single use packs and all the flavors and honestly all are very good and have no horrible tasting flavors.

    Good job to the crew and the team at tailwind for making such a kick butt item and helping reach my goal of obtaining my first buckle!!

  5. 100 Mile Fuel

    Posted by Unknown on 5th Aug 2015

    After suffering through nutrition issues in three different one hundred mile races over the past two years I went liquid. Introduced to Tailwind at the SD 100 (but I did not use it during the race), I used Tailwind at the AC 100. Tailwind satisfied my calorie needs and provided the energy necessary to get me to the finish line. Anyone who experiences nutrition issues in the longer trail races should try Tailwind.

  6. A True All in One!

    Posted by Tommy on 4th Aug 2015

    After crashing a few times on my long runs, I was looking for something to help me power through. Tailwind was recommended by my Marathon group. I received my order quick and to my surprise a handwritten note of encouragement. I've since used it on 8 long runs and have to say it delivers everything I need to get through the Hot and Humid summer days. So long beans, gels and blocks!

  7. A fantastic change - no more stomach cramps!

    Posted by Jamie VanderVliet on 3rd Aug 2015

    I've struggled for years finding the right combinations of fluids, honey stingers, gu products, and anything else you can think of. Finally I've found tailwind - I mix it up and drink it during any run over 5 miles, especially on very hot days. I'll alternate with water after a couple of hours of running because I do notice a sweet taste build up in my mouth after drinking it for so long, but it is not too bad and seems unavoidable no matter what product you use. So far it has provided me with energy on my hottest and longest runs and its the only product I'll be using during my next marathon. I rarely get stomach cramps and now if I do, I can usually pinpoint something else that is causing the cramp - I trust in tailwind to get me to the finish line. Thank you!

  8. Best fuel I have ever used

    Posted by Laura B. on 3rd Aug 2015

    I used to use GU gels, bars, and Endurox. Now I only use Tailwind, I have ran 2 marathons with Tailwind in my camelbak, I have finished strong and felt awesome.
    No need for anything else now :)

  9. Great product

    Posted by Tom Syre on 29th Jul 2015

    All you need. My strategy for long runs is to have two handhelds: one with 2.5 scoops Tailwind (naked) and one with water.

    No chews, no gels, no pills. Easy and effective.

  10. En Español

    Posted by Gustavo on 22nd Jul 2015

    He usado Tailwind por casi un año con excelentes resultados, he hecho varias competencias cortas y algunas largas como La Ruta de los Conquistadores solo usando este producto y la verdad me ha ayudado muchísimo. Adiós a los calambres.

  11. Wonderfully steady supplement!

    Posted by Elise on 22nd Jul 2015

    i loved the mandarin orange flavor and tolerated it easily through very hot training (bike and run workouts for upcoming triathalon)
    enjoyed trying the berry flavor and will purchase that next! it is almost funny how it really does begin to taste better as you get further along in a given workout!

  12. Just Wow

    Posted by Robyn on 20th Jul 2015

    Love this stuff! First, the flavors. I ordered the lemon, and also received a sample of the unflavored, which I tried first. It's not tart, not sweet, not salty, but somewhere in the middle. The best I can describe is sort of kefir-ish, but not unpleasant. In fact, I may order this as my go-to flavor next time. The lemon was also alright, but in endurance fuel I don't want zing pow zap either, nothing that will pucker my mouth, know what I mean?
    Now to the official stuff.
    This product works wonders. I don't have the sloshing or gurgling in my gut, everything absorbed quickly and efficiently, and I found that my legs didn't get fatigued while running. I have to do my training on the treadmill so I have it set right now at 3* incline for resistance. I'm training for a half marathon and after that for a mini-relay, and if all goes well with my knees will get back to doing a full marathon every year as well as other shorter races. I'm using Tailwind to replace the GU and the electrolyte mix I was using before in my hydration pack. I recommend this product to anyone who has to fuel on the fly.
    A note: I run in bear country. Bears can smell food, I have read, up to 20 miles away. Maybe that was a typo... maybe not. But I've always been concerned about carrying GU because no matter how hard I try I always get that sticky mess on my fingers, my clothes, and I have to pack out the empty packets too. Yes, I'm paranoid, but like I said, I run in bear country. The Tailwind is much neater to use and I do love that it's electrolytes and nutrition in one product.

  13. Perfect fuel for the long haul

    Posted by William Curtin on 20th Jul 2015

    Tailwind got me through a 50 mile run yesterday without any stomach issues whatsoever. Zero headaches, zero nausea. I kept my intake to about 2 scoops/hour, plus a little food (bloks, gels, fruit, peanut butter) just to have something to chew on while I ran. I have been using Tailwind for almost 6 months now, and I absolutely love it and believe in it.

  14. So far, so good!

    Posted by Betsy on 17th Jul 2015

    I'm getting ready for a 200-mile race in a couple of weeks and based on reviews by friends I wanted to give Tailwind a try. Indeed, it has a very mellow (and pleasant) flavor that I think will continue to go down easy toward the end of my race. I just did a 6-hour training run where I normally would take in 5-8 gels, but decided to just use TW. Happy to say there was no bonking!

  15. Great Product!

    Posted by Matt on 16th Jul 2015

    Got introduced to this product from a friend on a mountain bike trip and tried it out. Ordered my own as soon as I got home and haven't looked back since. I've definitely noticed the difference using a dilute solution during outdoor workouts on hot days (I live in Houston) were I sweat a TON. More sustained energy, no muscle cramping or stomach issues. Tastes good too! I like that it contains no colors or other unnecessary ingredients. Will definitely be keeping this stuff on hand.

  16. lots of energy. slightly salty taste

    Posted by Zeke Stanis on 15th Jul 2015

    very good product. I was impressed with the amount of energy i got while using the product. The salty taste was a little over powering. I have to bring another bottle along with me on the run to satisfy the hydration need.

    I would use this on my longer runs and race day. shorter training runs i would go with straight water

  17. Only use TWN

    Posted by Andrew P. on 13th Jul 2015

    It's all I need when out on the trails. For me, it's good for longer runs above 10 miles. I use both the berry and orange and have loved them! Will continue to buy TWN in the future for sure.

  18. Amazing!

    Posted by Dennys on 13th Jul 2015

    Training for Ironman 2015. I've tried other supplements and nothing works like Tailwind. They have a lifetime customer in me!

  19. Less salt more sweet needed

    Posted by Stacey on 10th Jul 2015

    I find the product a little salty tasting which is to be expected since it contains salt but maybe if the flavor was a bit stronger it would help offset the salty taste. Otherwise it dissolves well and my tummy tolerates it well.

  20. It's all you need, minus water.

    Posted by VanLooRunning.com on 9th Jul 2015

    I absolutely love this product. I made the switch over to just Tailwind nutrition at the beginning of this year and can honestly say that it's all you need. I've used it in all of my ultras that range from 50k to 100 mile races. If you ever deal with fatigue or cramping, ditch whatever you have and start training with Tailwind. You WON'T be disappointed!


    Posted by Roby T on 8th Jul 2015

    I had used other fuel, or liquid foods as my wife calls them, and I can say that this is one of the best ever! The easy it mixes and the subtle lemony flavor is great!! Looking forward to use it during my next race.

  22. Rocket Fuel

    Posted by Mike Holmes on 5th Jul 2015

    I started using Tailwind while training for Western States this year on all my long runs and on my 3 ultra races leading up to the Big Dance. It always provided the nutrition and electrolytes I needed for a balanced endurance performance without the problems and issues related to digestion and heat related problems. Great results and ease of use have made it as important as my shoes for my endurance adventures.

  23. Perfect addition to training

    Posted by Alicia on 1st Jul 2015

    Perfect addition to our Ragnar Relay run!

  24. No more cramps!!

    Posted by Mike on 1st Jul 2015

    I was having issues with cramps and a riding buddy suggested I give tailwind a try. I started using the tailwind endurance fuel and haven't had any issues with cramps since. The package showed up two days after ordering with a hand written thank you note and a sample of the other flavor of endurance fuel. Outstanding product with outstanding results.

  25. A great addition to the trail

    Posted by Tim on 1st Jul 2015

    I'm getting ready for some longer and more challenging trail runs this coming summer (Boulder, CO in late June and Mt. Whitney in mid-August) and a good friend of mine recommended Tailwind for some longer runs due to the nutrition content and mildness on the stomach. I got the Tailwind in time for the Boulder trip and used it for runs at Green and Bear Mountain, as well as a great road bike ride from East Boulder to Jamestown (a classic Boulder ride). I had to admit the Tailwind worked great for me and, although I did supplement with a little solid food, I found these longer and more challenging activities much easier to handle with the better nutrition and hydration from the Tailwind. Can't wait to tackle Whitney in August!
