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. It's even good when it's warm 5 Star Review

    (Submitted on 5th Sep 2016)

    I couldn't believe the claim that it would stay tasty all day. Nothing can taste good after four+ hours, especially when it's been sloshing around in a hydration pack, right? Wrong. The light flavor of Tailwind never gets sickly sweet or turns my stomach, even when warm. I have a favorite flavor (lemon), but have tried all of the flavors and could definitely use any of them during a ride or run. I'm a triathlete who uses Tailwind in training and during races and I have no complaints. So much better than the typical drinks and it mixes so easily that refilling my bottles on a bike course is a breeze.

  2. Great product, lousy bag closure. 5 Star Review

    (Submitted on 2nd Sep 2016)

    I do find your product to live up to it's claims. Still working on the proper proportions so as not to overly concentrate the mixture.
    The product packaging, specifically the bag closure design is worse than lousy. Pleas improve! Thank you.

    [Tailwind Response]: Thanks for the feedback, and yes we are working on that ziploc closure. Sorry about the frustration you experienced!

  3. Badwater Crew Fueling 5 Star Review

    (Submitted on 2nd Sep 2016)

    I used Lemon Tailwind while I crewed and paced the Badwater 146 Crossing -- running from Death Valley to the top of Mt. Whitney. So did the runner I was pacing. It kept us both happy and fueled in 120 degree temps. Thank you!!

  4. The Ultimate Test 5 Star Review

    (Submitted on 31st Aug 2016)

    During my runs I typically eat real food. Pizza, hamburgers, potatoes, pancakes... you name it. And I've never had any problems. When I read about TailWind I wanted to put it through the ultimate test (in my opinion). I ordered the variety pack of single servings and waited to try it during the first miles of a marathon. Never had it before. I randomly pulled flavors out of my waistbelt every hour, read the flavor and dumped it in my bottle. I finished the race feeling better than any other race. My energy levels were consistent during the entire race and I never had a flavor that I didn't like. Excellent stuff!

  5. I'm so glad I found Tailwind! 5 Star Review

    (Submitted on 31st Aug 2016)

    Tailwind endurance fuel is such a wonderful product. I do a lot of running and obstacle races using Tailwind is my water. Tailwind has just the right amount of each ingredient to keep me going. The powder dissolves quickly and tastes great.

  6. Keeps me going! 5 Star Review

    (Submitted on 29th Aug 2016)

    Tailwind is one of the first products that can use and not have to use other fuel sources. It tastes great cold or warm. I run in Houston and liquids don't stay cold for long. I can still drink this at room temp and it does not cause cramping or other GI issues. I highly recommend this product for marathon training.

  7. Great Stuff 5 Star Review

    (Submitted on 29th Aug 2016)

    This stuff rocks. I'm a marathon swimmer and now triathlete. Clean burning fuel for endurance. My son discovered it and he uses it for his soccer workouts. Highly recommended!

  8. 5 yrs using Tailwind 5 Star Review

    (Submitted on 27th Aug 2016)

    I believe it has been 5 years since first starting to use Tailwind. Been using it and nothing else ever since. NO GI issues, no issues of any kind. Just finished my 2nd Leadville Trail 100 MTB. Knocked 38 minutes off of first time, 3 years ago. Knew what my splits were so carried premeasured TW in ziplock baggy's for a couple of aid stations where I grabbed water. With Tailwind I have absolutely no worries about enough or too many calories, electrolytes, etc. It's like getting ready for a ride; pump air in tires, fill camelbak bladder with water and TW, go ride. Doesn't get much more simple than that. At age 67 y/o thinking I have a few more chances to improve my time at LT100. But darn, those CO guys and gals kick butt! All good though.

  9. Magic Unicorn Potion 5 Star Review

    (Submitted on 27th Aug 2016)

    Both my husband and I love training with this. From marathons to 100 mile trail runs this is absolutely our go to. It fuels amazingly and never makes us sick. I had gotten tired of running marathons because it seemed there was absolutely no way to run beyond 22 miles without just crashing regardless of gel and various drink intake. After switching to Tailwind I hit no wall and felt amazing. It renewed my love for running!

  10. This Stuff Is Gold 5 Star Review

    (Submitted on 25th Aug 2016)

    I've been struggling with my fueling for about a year. I had been a gel girl, which was fine, but was before I got into Ultra running. Now that I'm facing my first 100M, I knew I had to buckle down and get this figured out...before race day. I had heard so much about the Tailwind that I decided to give it a try. Can't tell you how much I love this stuff!!! Now that my fueling is settled, time to go get that buckle!

  11. Saved my endurance career! 5 Star Review

    (Submitted on 25th Aug 2016)

    I've only been running for about a year. When I started training for my first marathon, every time I tried to take in calories, whether by gels or real food, I was hit with a wave of nausea almost instantly. How the heck was I going to be a runner if I couldn't take in calories!? Enter Tailwind. On the recommendation of an ultra runner, I gave Tailwind a shot in a last ditch effort to pursue my goal of becoming an ultra runner. Tailwind saved my ambition - it was easy on the stomach, tasted great and gave me the calories needed to run long distances. Thanks to Tailwind, in the last year I've completed 10 races including 6 marathons (5 being ultras, up to 100k) and will tackle the 100 mile distance in October. If you have any GI issues whatsoever, or just need a boost during training, give Tailwind a shot. You won't regret it!

  12. Life-changing stuff 5 Star Review

    (Submitted on 22nd Aug 2016)

    Before Tailwind, I was really more of a wannabe-endurance athlete than anything else. I had one long ride I'd do three or four times a month, and while I loved the thought of being someone who could do that, the actual doing was pretty scary. There were times I'd be getting to the halfway point wondering how I even made it that far and having no idea how -- or if -- I'd make it home. The dreadful last 10 miles or so, being so shaky and crampy and bonky I would sometimes have to just get off and walk because I couldn't tell which of the two roads I was seeing was the one to ride on. When I did get home, the cramping would stay with me for the rest of the day, making riding not just scary, but debilitating as well. I kept doing it because I'm stubborn, but deep down it felt like what I was doing “for my health” was actually bad for me.

    I thought I was just too old (55½) and too weak, turns out I just needed the right fuel. I was blown away by what a difference it made. Before Tailwind, on the weeks I didn't do my long ride I'd hardly ever make my 210 mile/week goal, and now I'm averaging 260. With nothing but a couple bottles and a nice baggie full of Tailwind I can hop on the bike and go for a 5 or 6 hour ride and enjoy every minute of it, then get home and carry on with normal activities.

    That's not just game-changing, it's life-changing.

  13. Tailwind helps me achieve victory! 5 Star Review

    (Submitted on 20th Aug 2016)

    I've been using Tailwind for about 8 months now and it covers all of the things I've been looking for in hydration! No belly bombs, nice amount of calories, tastes awesome even the naked flavor, it moisturizes my mouth, and keeps me hydrated! It was 100+ degrees last weekend for the Cool Moon 100, I stayed nicely hydrated & kept calories in check as I lead the race and won! It's things like finding the right products like this that can help me and anyone achieve their goals! Thank you for your awesome product! Tina Shinn

  14. Go body go, sorry GI you are silenced! 5 Star Review

    (Submitted on 19th Aug 2016)

    Great product!! Easy to use in any athletic setting. I have to admit that the first time I tried it I was not convinced but a second try got me hooked ..

  15. Great Fuel 5 Star Review

    (Submitted on 16th Aug 2016)

    Training for 50 mile. Works great for long runs.

  16. Better than Gatorade 5 Star Review

    (Submitted on 16th Aug 2016)

    I am on my third bag of tailwind and love it. I mostly use it for my runs and races or hydration if I slacked that day on water. Recently I wanted to use up my Gatorade that has been sitting for a few months. When I tasted the Gatorade, it tastes really fake! I never knew how bad Gatorade tastes until I had something better to compare it to.

  17. Awesome fuel 5 Star Review

    (Submitted on 16th Aug 2016)

    My wife and I both loaded this in our hydration packs for a 60 miler on our tandem. We beat our average speed by more than 2 miles an hour and finished strong. The taste is pretty good, and we really felt energized at the end. Add in the fact that it eliminates all of the hassle of carrying and finding food and it really is a winner.

  18. You gotta try this!!! 5 Star Review

    (Submitted on 13th Aug 2016)

    Tried every product known to man regarding hydration and fuel while riding and racing mountain bikes all over the country - NOTHING WORKS BETTER THAN TAILWIND!!!

    For really long, epic rides where cramping could be an issue, I throw down a 4 oz bottle of sports pickle juice (or 2) about half way thru the ride and I'm good to go.

    Run, don't walk, to Tailwind's website and try it for yourself - you will NOT be disappointed!!!

  19. 32 Mile M2O Channel Crossing 5 Star Review

    (Submitted on 12th Aug 2016)

    This is the third year my daughter and I took on the Kaiwi Channel (Molokai to Oahu) with confidence using Tailwimd. It's the best nutrition we've come across for the distance paddleboard races we live for, especially when traveling in hot environments. Recommended!

    And a great bonus is the personal care and quality the Tailwind Team delivers on every order. They care about their product and the athletes that use it.

  20. Doesn't Leak! 5 Star Review

    (Submitted on 9th Aug 2016)

    Great bottle, first one I've had that is 100% leak proof after having it more than a month!

  21. Great drink at a variety of concentrations 5 Star Review

    (Submitted on 8th Aug 2016)

    I love the pan-molarity of this mix. Half scoop, one scoop, two scoops in 24oz water all taste good and have the desired effect. All the flavors are great, so I'm working my way through the big packs now. Has anyone tried adding their own flavors to the "natural"?

  22. Great fuel for long runs. 4 Star Review

    (Submitted on 8th Aug 2016)

    Tried Tailwind at the North Face Challenge-Ontario and was surprised how good it tasted. It sat well with my tummy and provided hydration, electrolyte and fuel in one fluid. Great product.

  23. The best! 5 Star Review

    (Submitted on 8th Aug 2016)

    I've been using Tailwind for a couple years now, everything from a half marathon to a 24hour obstacle course races. This product truly works! Tastes great, gives you the boost you need, no stomach issues & just an awesome overall company!

  24. Does exactly what it says!! 5 Star Review

    (Submitted on 7th Aug 2016)

    Couldn't have been happier using the unflavored endurance fuel for 6.5hrs of a Spartan Beast. Was so easy on the stomach that in comparison, it was pure water in the late stages of the race that seemed harder to deal with. Definitely will be my only choice for long hot races in the future.

  25. Easy to Drink! 5 Star Review

    (Submitted on 5th Aug 2016)

    Used the Mandarin Orange flavor on my first 50M trail run and mixed it to be a little more concentrated than the directions called for. Ended up using about 2/3rds of the medium size bag in 140oz of water and it was perfect for me. I did supplement with some real food because I just felt lie I needed to, but it was great to have Tailwind with me to drip calories in every few minutes while I was out that day!
