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. No Problems

    Posted by Brant Butler on 15th Dec 2014

    I took this stuff for a test run on a long and difficult trail with lost of climbs and descents and it worked perfectly. Normally I end up cramping near the end of my run on this particular trail, no matter how I fuel with gels and salt tabs and water, so I honestly anticipated the cramping even with Tailwind. Well the cramps never came, I never felt hungry, never felt thirsty, and my stomach didn't feel full or upset at any point. This product is great, and it is all I will be using for my next race as well as my first 50k coming up in March. Thanks Tailwind for an awesome product and great customer service!

  2. Tailwind wins 2014 Hellhole Gravel Grind Stage Race

    Posted by James Allen on 10th Dec 2014

    I was able to secure and maintain a commanding lead in the Men's Open category of the 2014 Hellhole Gravel Grind Stage Race with the support of Tailwind Endurance Fuel as my primary calorie source.

    With only a single aid station on a 73 mile course Saturday and a single aid station on Sunday's 77 mile course; it was imperative to not only calculate how many calories I would need to consume but to also be confident that those calories could sustain my efforts over an extended period in the saddle.

    I'm pleased to say that Tailwind exceeded every need and never gave me worry that I would not have enough calories to finish and secure a gratifying win. Thank you to the crew at Tailwind!

    Go Tailwind, Go!

  3. The Kick without getting Sick

    Posted by Mike on 3rd Dec 2014

    Product works awesome without any stomach issues. THANKS for the great personalized service. I have already told the entire running bunch about your products (and even provided them with some samples).

    I've tried almost every brand and finally found the ONE!

    Keep up the great work - you have a new customer for life!


  4. Worry-free sustenance for the long run

    Posted by Paul on 1st Dec 2014

    I've recently switched to Tailwind after previously relying on Gels and S-Caps and then to UCAN. With these previous strategies, there was too much logistics involved and needing to keep track of doses and times for consumption.
    With Tailwind, I don't need to keep track of times anymore. I just drink when needed and each swig comes with nutrition, electrolytes and hydration. This regimen also doesn't prevent me from sampling the treats at the aid stations, or consuming a gel or two for an extra boost.

  5. Excellent Bulk Deal

    Posted by Brandon S. on 13th Nov 2014

    I tested out Tailwind with the stick packs, allowing to identify the flavors that I like best. I ended up then buying a large bag of the Lemon and Mandarin Orange! They are both incredible! With the bulk bags, I can easily mix a bottle at home on the way to a shorter run... or I can put my Tailwind into smaller bottles to transport in my running vest to refuel at springs along the way!!

    I love your product and will continue to use it! I have a steep 50k (over 10,000' gain) and other races coming up, Tailwind has kept me going strong on my training runs and I've not had one cramp or stomach issue. I love this stuff.

  6. Don't leave home without it!

    Posted by Colin Gulley on 12th Nov 2014

    I have been using Tailwind for two years now and am completely sold. Last weekend I finish a Trail Marathon fueling only with Tailwind. Earlier this year I had a strong 4th place finish at the Laurel Highlands 70 mile Ultra in Pennsylvania, fueling exclusively with Tailwind, plus one packet of Justin's Almond Butter. I also set a new FKT on the Bigelow Range Traverse in Maine only using Tailwind. As I have become better at knowing how much Tailwind I need vs water depending on the temperature, terrain, mileage, etc, I find it to be the perfect fuel for me. It's a simple, I don't have to over think my nutrition, and can focus on running. And I find the naked flavor tastes good all day long.

  7. Dependable

    Posted by Bill West on 11th Nov 2014

    I used the naked endurance fuel all season and it is great stuff. I did not find my self getting tired of the taste. It really does keep me hydrated and does not seem that I take as many gels. So, I think that it is exactly as advertised. I really like it

  8. THE BEST endurance fuel I have EVER had!

    Posted by Paleo Running Mom on 11th Nov 2014

    I absolutely LOVE this product! I was apprehensive about trying something via mail, and was so happy that I took the gamble! I usually have oversensitive stomach, and any sports drink usually makes me feel queazy or ill! THIS DID NOT! I am a true believer in this product, and will use it for my running fuel for now on!

  9. Amazing!!

    Posted by Gustavo on 11th Nov 2014

    What else can I said about Tailwind, it really did the magic!!!

  10. La Ruta 2014

    Posted by Ray Rowland on 11th Nov 2014

    I used Tailwind as my primary source of calories and electrolytes for this year's La Ruta race in Costa Rica. With no support team, other than the nuetral checkpoint stops, I relied upon Endurance Fuel, a few protein bars and some aid station bananas (that didn't have the gigantic wasps). I didn't bonk or get muscle cramps the entire race. Thanks!

  11. great product for endurance athletes

    Posted by Unknown on 10th Nov 2014

    I used this product for the first time last weekend for a 50 mile trail run and absolutely loved it! I highly recommend making this your primary, or only, fuel for long distance events and training.

  12. Great Product!

    Posted by Carrie on 10th Nov 2014

    This is a great product for those who can't use other forms of nutrition when they run. For whatever reason, I struggle with digestive issues during runs. This product helps me stay hydrated without the stomach issues.

  13. Awesomely refreshing nutrition.

    Posted by Turboletti on 5th Nov 2014

    I had heard a lot of great things about Tailwind Nutrition powder, so I finally bit the bullet and bought a sack.

    It lives up to its word-of-mouth reputation. It is great: is it not syrup-y or sticky like other electrolyte drinks, and it goes down clean & tastes refreshing.

    I've shared it with my running & ultra friends who all agree and intend to replace their traditional endurance nutrition needs with Tailwind. Great product, keep it up!

  14. Pinhoti 100

    Posted by Burke on 4th Nov 2014

    I approached Tailwind with a very skeptical attitude, but I needed something to fix my stomach issues. It has performed as advertised for me. I used Tailwind during the 2014 Pinhoti 100 Mile Endurance Run. I did supplement with some aid station food and a few things that I like to eat in these events. I used Tailwind for the bulk of my training for Pinhoti, including a 50 mile race in 90+ degree heat. I just don't seem to get energy drops, cramps, or stomach issues when I used it.

  15. Almost perfect?

    Posted by Jerry Doyle on 3rd Nov 2014

    I had been encouraged to try this product for two years by my running partner! I finally did. I love it! I tried the caffeinated option first and now I'm experimenting with the non-caffeinated. I use for 20+ mile runs and while I have cut down considerably on the amount of "solid fuel" I still find I need some here and there. But overall I have to say that I really like the product and have yet to meet a flavor I don't like!

  16. Perfect combination for Endurance Athletes

    Posted by Matthew Owenby on 3rd Nov 2014

    This stuff is great. It's the perfect combination of what every endurance athlete needs to complete their activity. I would highly recommend this to anyone doing any type of endurance activity.

  17. Great stuff

    Posted by Unknown on 2nd Nov 2014

    I've been using Tailwind since the summer and it has not let me down. Yesterday I was able to complete a 50km trail run using Tailwind as sole nutrition. No stomach issues whatsoever.

    I am confident in this product and will be using this for my first 50-miler later this month.


  18. Wall, what wall?

    Posted by Unknown on 29th Oct 2014

    I just ran the Hartford Marathon a couple of weeks ago. It was my third marathon overall, and my first in almost ten years. I ran NYC in '05 and hit the wall so hard I bounced. This time I ran with Tailwind in my hydration pack (hey, I trained with it so I ran with it) and just couldn't find the wall. I PR'd by over an hour even with not running for three weeks before due to a knee issue. This stuff is the best and I will be using it for all my races and long training runs. Now if I could find a pack that won't break half-way through...

  19. No gut bombs!

    Posted by Michael on 28th Oct 2014

    I have used a wide variety of nutritional products to varying degrees of success, Hammer, Osmo, Skratch etc. I came across Tailwind in a local Bay Area running shop SFRC. By the time I came across it it was the end of the triathlon season so I have only used the product for 2.5 to 3hr trail runs and 4 to 6hr rides. I tend to get GI issues with other products, I have no idea why. Other products would make me feel nauseous as soon as I swallowed a large mouthful out on a ride - not ideal. I typically mix 1 scoop unflavored with 1 scoop flavored in a 24oz bottle. This works well for me and tastes great. I love their tag line of no gut bombs, it really is spot on. I have had no nausea or GI issues while using this product. The real test will be using it to run off the bike at a long distance tri next season, but I really can't see it being a problem. I really like this product. Plus, coincidentally a tailwind is my favorite type of wind! I wish they all were tailwinds.

  20. First 100 without stomach issues!

    Posted by Jen Sorrell on 27th Oct 2014

    I just ran my 8th 100 this past weekend and it's the first one with zero stomach issues!! Thanks so much for a great product!

  21. Only thing I use to hydrate while running

    Posted by Laura on 25th Oct 2014

    Tailwind is the only product I now use for all my running and workout needs. I have gotten rid of all my GU and other brands of powders. Tailwind is the only product I have found that hydrates me and keeps me going without having to use GU or food on my long runs. No stomach upset or anything, its a great product. I just completed a half marathon and wasn't sore the next day. Tailwind also supplies me with the potassium that I need to run, I have usually needed to carry a salt shaker during races to put additional salt in my water at aid stations. No more do I need to do that and I am so happy with Tailwind, I am now a customer for LIFE :)

  22. First 50 mile race!

    Posted by Shawn Sinclair on 23rd Oct 2014

    I ran the Table Rock Ultra 54 mile race this past Saturday with 23,000' of elevation change. I am a big guy 6'3" 200lbs, so typically no matter what I have tried I always cramp. I put 5 servings of Tailwind in my handheld bottle and carried two more bags of 5 servings each. Then I had three more bags in my drop bag at the halfway point. So I drank 3000 calories worth during the race. The only other food I had was half a banana.

    I made it to the finish line without cramping or getting nauseous. The last four miles were my fastest and I finished 13th overall. I am completely sold! I will be using and recommending Tailwind at all future races. Thank you!!!

  23. Something So Simple It Is Amazing

    Posted by Anush on 22nd Oct 2014

    When you are spending long hours on your feet, there are many things that can go on in your head. One of them, a pretty constant one at that, is the physical feedback from your body. Your legs hurt, your shoulders are sore, your neck is stiff, but most important of all is your stomach. This single part of the human body can wreck havoc on even the most beautiful of days. I honestly believe, ever since I started using Tailwind, I have received nothing but positive feedback from my stomach. I don't even think about it at times. I always feel like I have enough strength to take the next step.

    Thank you!

  24. Perfect Caloric Base

    Posted by Tyler on 22nd Oct 2014

    As a Type I Diabetic who participates in endurance runs beyond 50 miles, having a caloric base is essential in the prevention of hypoglycemia during the course of a long run and Tailwind has proven itself to be my go-to. In the past three challenges, I have not suffered from hypoglycemia even once with a happy belly all along the way. I use two 17-oz bottles with one scoop of the good stuff in each bottle, and with some supplemental real food along the way, I'm able to trot along all day and night. Thank you for developing this product that fits a diabetic endurance athlete's needs.

  25. Best stuff ever!!!!!!!

    Posted by Eric on 21st Oct 2014

    I have continued to use Tailwind for my Ironman Florida training and it has been working well on long runs (2-3 hours) and long rides (6-7 hours). I have tried everything in the past (UCAN, Perform, etc.) and they all gave me stomach/GI issues including nausea, bloating, etc.

    Tailwind is absolutely the best stuff ever and I will give it a tremendous amount of credit for me being able to complete my first Ironman in just a few weeks.

    I am almost ready to consult them to see if I can become a distributor in the Houston area! This stuff is a gem waiting to take off, because people still don't know much about it down here.
