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. Shhh... It's a secret.

    Posted by B. Diggs on 21st Jun 2015

    I would love to give tailwind a descriptive glowing review, but I can't. I don't want my running/cycling buddies finding out about my secret weapon.

    Also, the handwritten thank you notes from the tailwind ladies keeps my wife on her A game.

    Please always be made in the USA. Thanks!

  2. Great Replacement

    Posted by Unknown on 20th Jun 2015

    Using tailwind before, during and after long workouts has been key in how my husband feels post workout.

    Easy on the stomach, and very beneficial replacement of electrolytes after sweating profusely during a run.

    Post run muscles feel much less fatigue using tailwind as opposed to H2O. Great product.

  3. The only fuel I use now!

    Posted by David Kurneta on 18th Jun 2015

    Like so many of us who love endurance athletics, I've tried all the gels, bars, powders and whole food options out there over the years. They all worked to varying degrees but they all had drawbacks that left me looking for something better. After watching the Youtube videos of a certain flame haired ultra runner/internet personality, Tailwind popped up on my nutrition radar. I tried it out during my training for an upcoming 50k and it was amazing! It truly is all you need all day long. It kept me going strong in mountain marathons and ultras in the desert without using any other nutrition along the way. Do yourself and your performance a favor and get some!

  4. All you need, all day. Really?

    Posted by James on 18th Jun 2015

    Yes! A fantastic product that really is all you need. I have been using it for over 6 months now without any issues. It makes my 2+ hour runs much easier and my stomach is still in great shape to start my recover meal as soon as I stop. I had a 7 hour effort this spring and Tailwind pulled me through with flying colors. Not to mention the customer service is top notch. The Tailwind team has knocked it out of the park!

    Works as advertised, I use it on both MTB and trail ultras and it the best I have tried. In this brutal summer heat it has provided me the electrolytes I need for 4 hour MTB rides and 6 hour trail ultras.

  6. Never had such an easy fuel before

    Posted by Cristin on 15th Jun 2015

    I love tail wind. I have a very picky stomach. It rejects most electrolytes, drinks and gu, and chews.
    I used tailwind in a 55K trail race and only ate one package of honey stingers the whole time, and drank tail wind. I did bonk at one point, but not due to my fueling, more due to conditioning and the race. Im a flat lander, and it was at altitude. :) But, I finished strong, and recovered shockingly well.

    Thanks Tailwind!!

  7. Love it

    Posted by Unknown on 12th Jun 2015

    My new go-to!

  8. Hasn't let me down!

    Posted by Sandra D. on 12th Jun 2015

    I've been using it while training for a half iron man. I've been using it mainly for the biking section but more recently also for the run portion.
    It took a few trial and errors to get the right amount of powder for my taste. I'm fairly new to the sport and cannot say I've tried many other products to compare this to. The taste is definitely better and less sweet than your average sports drink. I exclusively use Tailwind in all my bottles for long bike rides. I have had no problems with cramping whatsoever. I do use the occasional gel and snack along side of it, but bringing in this product has definitely helped with my calorie intake in my rides.
    Very easy on the stomach, which I'm very pleased about! No bloating or any kind of discomfort and I don't get sick of the taste at all.
    The only issue I have found is that it does turn water a little thick, which I'm not surprised, but sometimes it leaves a bit of thick saliva on the back of my throat. Nothing that a drink of water after a ride can't fix. This is my only found issue.

    I remember during an Olympic triathlon once, a guy got off his bike and as I went closer to his I asked if he needed help. He told me he started getting cramps. I'm very pleased to say that up until now, while using Tailwind I have had zero cramps (racing or training) and I'm convinced it is due to good nutrition. My half ironman is coming up and I'm confident than Tailwind will be a key part of a achieving my goal.

  9. best endurance fuel I've ever tried

    Posted by Unknown on 10th Jun 2015

    Over the past 8 years I've tried many nutrient products for Ironman, 70.3, and marathons and ultras and had gastro issues with gels and other products I've tried. Tailwind has alleviated these problems while still meeting my nutritional needs.

  10. It works for me.

    Posted by Dennis on 10th Jun 2015

    I have finished 2 40 mile runs the last couple months using Tailwind, and it has worked for me. The flavors are all mild enough that they overwhelm the taste buds, but I actually like the naked best.

  11. Really all you need

    Posted by Unknown on 10th Jun 2015

    Just completed another 50 miler with 90% of my calories coming from Tailwind and I shaved a couple hours off my best time! Tailwind is the best.

  12. Worked as advertised

    Posted by Unknown on 9th Jun 2015

    I used tailwind for my first 100 miler. It worked great. Gave me lots of energy without the bloat.

  13. Great Product

    Posted by Bill West on 3rd Jun 2015

    I have now been using Tailwind Naked flavor for over a year and it just simply works. Keeps me going. I would highly recommend you give it a try.

  14. No Cramps, No Bonks, No Kidding

    Posted by Kevin King on 3rd Jun 2015

    I was terribly skeptical but drank the Cool-Aid any way. Away I came amazed after my last 2 x 50K runs started and finished with no cramps, no bonks, no kidding. I drank the product exactly as prescribed on the bag with only 1 variance - I added a small amount of chia seeds to the powder for some extra nutrition and bulk in the water bottle. I am a believer.

    Another quick story. My wife and son in law and I did a 50 mile bike ride last weekend. This is the longest ride ever for my son in law. By about mile 40 he was in bad shape. Aaron was having a horrible low spot and cramping badly. I gave Aaron a full 20oz bottle of Tail wind mixed Heavy and said "drink as much of this as you can stomach". Aaron complained of the taste calling it "Sweat Water" but drank 2/3 of the bottle any way. After 10 minutes of limping him along the young man had a miraculous recovery! Aaron crushed the last 10 miles of the ride and promptly asked me "What was in that sweat water?".

  15. Awesome!

    Posted by Rachel on 1st Jun 2015

    Love the flavors. Not overwhelming. Just right to keep you going through those long grueling hours.

  16. Double Metric Mountains of Misery

    Posted by Unknown on 1st Jun 2015

    I have used Tailwind for a 12 hour mountain bike race and most-recently for the Mountains of Misery Double Metric Century in Western Virginia, near Virginia Tech. My jersey pocket looked pretty funny at the start jammed with 7, 3 scoop servings of Tailwind in plastic snack bags. The ride ended up a 129.6 miles and 13,521 vertical feet. Tailwind was my only nutrition during the ride, and it worked perfectly throughout the ride. Thank you.

  17. This just plain WORKS for me!

    Posted by Mark on 27th May 2015

    I have been using Tailwind for just under a year now. I just finished by first 50-mile trail race. This race (Jemez Mountain Trail Run) has over 11,000 feet of elevation gain and is considered a very difficult 50 miler. Tailwind was all I consumed for the entire 12.5 hour run. Plenty of energy, no "bonk" or "wall" and no muscle cramping in the last long downhill. I used straight Trailwind for the first half and switched to the caffeinated version for the 2nd half. Even during the finishing miles, the taste was still pleasant and my stomach felt great all day. I credit Tailwind as a key part of my recent success at the longer mileages.

  18. Love Tailwind! It provides calories, electrolytes and tastes great!

    Posted by Christy Gonzales on 26th May 2015

    I was introduced to Tailwind by a friend who participates in ultras and multiple Ironman races. I tried it and loved it! Tailwind provides the calories I need, electrolytes, tastes great and is easy on the stomach. I had a successful Ironman race and will continue to use Tailwind products! I can't recommend it enough!

  19. Nothing helps a race performance like Tailwind.

    Posted by Scott Gall on 26th May 2015

    First product I've found that both decreases the need to carry anything else for nutritional intake and increases my ability to keep the effort high throughout the entire duration of a race or long effort.

  20. Is the naked flavor secretly sweet tarts?!?

    Posted by Chad on 25th May 2015

    I got in a 20 hour run this past weekend and used tailwind exclusively for the first time. It performed just as I was told. For once, my stomach was fine for the entire day. The entire day. It was so nice to not have to worry about my nutrition being the variable that goes wrong when you're 80 miles into a run. And I'm pretty sure the naked flavor tastes like sweet tarts.

  21. What I am Filling My Hydration Pack With!

    Posted by Paul Litwin on 25th May 2015

    I had been looking for years for the best hydration/nutrition for marathons and ultras. I've had too many races where I was under-nourished. But I think I may have found the solution for me: Tailwind Nutrition Endurance Fuel: in one formula which I add to my Nathan hydration pack that covers nutrition + hydration + electrolytes. For my 15-20 mile training runs I have been using 2 scoops of the mandarin orange plus a half scoop of the unflavored for every 24 ounces and filling my hydration pack with 48 ounces of the mix. I supplement with some Honey Stinger chews. So far, has worked very well for me. As an ultrarunner & marathoner, I am always worrying with issues in my races like training, pace, hydration, nutrition, etc. By using Tailwind, I can now eliminate my nutrition, hydration, and electrolyte concerns and focus on the remaining variables. This is huge. Thanks, Tailwinds.

  22. naked flavored fuel

    Posted by dale on 25th May 2015

    great product....no stomach issues at all. the hand written note is a great touch! thanks!

  23. Perfect Running fuel

    Posted by Dave on 23rd May 2015

    Awesome, simply the best and I have tried many many different brands.
    I used this in my first 50 miler(American River 50). It just works! Oh, I places 12th in my age group 45-49 out of 146.
    Now my son uses it during his High School MTB races. Oh, did I mention he is the #1 points leader in the JV boys NorCal MTB division.

    Thank You Tailwind!!! Im looking forward to my first 100!!!

  24. Great stuff! Easy on the stomach and keeps you going.

    Posted by James on 19th May 2015

    I was looking for nutrition which wasn't super sugary like some of the gels on the market, which directly contributed to me feeling nauseous on some of the longer runs. Tailwind was the super fuel I was looking for. Sustained energy with a great taste. Thank you!

  25. Does exactly what is promised!

    Posted by Olivia on 19th May 2015

    Tailwind doesn't upset my stomach or weigh me down. It also isn't carbonated, so it doesn't create pressure inside my water bottle to the point where it starts to leak, like other products. I can run for hours on only Tailwind and I don't feel deprived of anything.
