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. 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.

  2. 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.

  3. 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!

  4. 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!!!

  5. 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!

  6. 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.

  7. I've tried a lot, and this is the best.

    Posted by Bryan West on 17th May 2015

    I've been running quite a few marathons & ultras for several years now, so I've tried a lot of fueling/hydration products. Tailwind is BY FAR the best. For fueling, it keeps me more full and energetic than any solid food or gel I've tried. For hydrating, it keeps me hydrated and my electrolytes balanced better than any sports drink, tab, or cap I've tried. Not only that, but it does them both in one great tasting, easy to mix & use place. Simpler than any other, better than any other. What more could you ask for?

  8. Instead of snacking on Fat, I take a Tailwind

    Posted by Dan on 15th May 2015

    I am a big guy, but I do go out and run. I also like to eat, I especially get hungry when I lift and run late at night. In the past I would munch down on chips, cookies, or whatever I have in my fridge. Now I have some Tailwind in the morning with my morning bottle of water, when I go out for runs, and when I am having those midnight hunger pains.

  9. Old guy uses Tailwind and finishes 50K

    Posted by John Woods on 15th May 2015

    I used tailwind on a 50K last weekend that had 7000 feet of climb in it and some very technical trail. I carried it with me and they helped me mix it at the aid stations. It got warm during the run. I never felt hungry or felt a blood sugar low. I will use it this summer and for my 100 miler this fall. I am 61 and have been running for 50 years. I appreciate the opportunity talk about this product.

    Thanks Tailwind!


    Posted by Unknown on 15th May 2015

    Tastes great, no stomach upset, and provides all the energy and fuel needed without the crash. Highly recommend!

  11. Never Bonk Again!

    Posted by Jim on 14th May 2015

    I ride endurance rides on remote gravel trails and have dealt with GI issues for years. Last year on a long unsupported ride we stopped in towns that where supposed to have places to grab some food. Unfortunately those places closed and eventually we ran out of food, fuel, and energy. This year I searched for an easy way to carry a high energy fuel that wouldn't bother my stomach. Trailwind has been the answer! I take two bottles with me and back up servings in a plastic bag. In a small package I can carry enough to keep me fueled and grinding for the entire ride.

  12. Great Product!!

    Posted by Bill on 13th May 2015

    Since I started using this outstanding product, I’ve gained a second wind. My times and recovery, as a result, are much quicker.

  13. Saved me

    Posted by Bryan on 13th May 2015

    For years I was that guy feeling awful during races and always struggling with what to eat and drink. I had heard about tailwind and was desperate for something to work.. This stuff works. I have used it this past year for all my long training runs and my first 50 mile race. It has given me confidence in my training and my fueling. I don't have to worry about whether I will "get lucky" with my stomach during a race. I know that I will have that aspect of my race nailed down and I can just worry about running fast and having fun.

  14. First Timer

    Posted by John Hall on 11th May 2015

    Just tried Tailwind for the first time and loved it. Used it on a 23 mile training run just to see how it worked for me. Used the Mandarin Orange flavor which was not sweet at all. No after taste. Best part was how well my stomach handled it after 3 hours of using it. This is normally where I have issues and I had none. I did not use any other nutrition and never bonked. Even felt strong enough to run some faster miles at the end. Looking forward to using it during some longer runs and races.

  15. Great for my ultra

    Posted by Mark on 8th May 2015

    Provided an excellent supply of energy during my running of the Cactus to Cloud 50k. Quite a challenging event, but I felt great throughout.

  16. the scoop

    Posted by thae kweon on 8th May 2015

    I love the large pouch for use at home when I am not racing. I love the product and now it is even quicker for me to mix up a batch and go running. Everyone should use TAILWIND.


  17. The only fuel/nutrition I use!

    Posted by Dede Owens on 7th May 2015

    I first tried Tailwind after hearing the hosts of Trail Runner Nation podcast speak its praises. I have not used any other type of fuel/nutrition for my long runs, races, or ultra events since. That was 2012. I have a hard time with races, and cannot rely on aid stations because I have Celiac disease. This disease means I cannot have anything with gluten- think wheat, barley, most oats, etc. This rules out the traditional fuel sources that most runners rely on such as gels and bars. Tailwind is safe for me to drink and meets all my needs. When I rely on Tailwind, I know I am getting sufficient and satisfying hydration as well as fuel. I use Tailwind exclusively on any run over 10 miles whether I have it in my Tailwind bottle, or a full hydration pack. I bypass all the aid stations and keep on running. I may sneak a salted potato late into an ultra, but who can resist that. It's Tailwind all the way!!

  18. works for me!

    Posted by Chas. B. on 7th May 2015

    Ran my first trail Marathon with tailwind and had plenty of energy and no G.I. issues the whole race. Only been using it this past month but impressive thus far.

  19. Easy - Clean - Keeps You Going

    Posted by Jeremiah Wean on 5th May 2015

    It seems hard to believe that you can carry in your hand all the calories you need to cover 50 miles and longer. I gave it the try and it really is "all you need!"

    The product held up through a 50 mile race is 95* temps. The only thing I had all day was Tailwind. It has a great taste that never wears on you.

    I have used this in multiple other training runs as well as green marathon races that let you bring your own bottles and nutrition.

    Give it try, you will love it!

  20. Can't live without it

    Posted by Chris Cover on 5th May 2015

    I love you guys, another successful usage story just yesterday, 4.5 hr ride on nothing but TW, there is not another nutritional product that can possibly do that, or even make that claim, its just so preposterous that no company would even dare, but not you, because its the crazy truth. I tell all my endurance athlete friends about it,and several have switched from what they were using, thanked me and wished they had done it sooner.

    its amazing.

  21. Adventure Race Tested, Stomach Approved!

    Posted by Ben Brewer on 5th May 2015

    I love Tailwind! I train, race and, occasionally, recover from victory celebrations with this stuff!

    It is easy to drink, mix, pack.... the list goes on. If you haven't tried it, don't cheat yourself out of one of the best activity nutrition things on the market.

    No stomach aches. No nausea. No lows.(when done correctly)

    Lifetime customer.

  22. Tailwind Works

    Posted by John C Harris on 4th May 2015

    I have been strugglign with nutrition on the bike for a couple of years and tried Tailwind at the recommendation of my coach. I was surprised with how well it worked and how I felt it so quickly. The item mixes well (a big issue with me with other products clumping on the bottom of the bottles) and the taste os so light it is almost indistunguishable which is great as well. Love it, and will be ordering more soon.

  23. It's for real for ultra/endurance events.

    Posted by Steven on 4th May 2015

    I have experimented with many nutritional products over the years. I got tired of dealing with electrolyte pills and gels. It's really great to just think about consuming a certain volume of fluid and that's it. Also, the tailwind tastes great after many hours and I will just drink that and munch on whatever looks good at aid stations. I have used tailwind at my last several ultramarathons from 50K to 100 miles and had great success.

  24. Finally found something that works

    Posted by Chris on 1st May 2015

    I could not be happier with this product. I trained with it in preparation for my last 50k. It was all I needed during the race, and I plan to use it for a 100k in a few weeks.

  25. Satisfied and no stomach upset!

    Posted by Unknown on 30th Apr 2015

    Have used for 10 days now on a couple of 60 mile bike rides and a few 3 hour mountain bike rides. Happy with the mild flavor and no stomach discomfort. I seem to have a sensitive digestive system with other products and am glad Tailwind has so far proven not to give me stomach issues...
