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!

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. Excellent Flavor & Perfect Fuel Source 5 Star Review

    (Submitted on 16th Mar 2016)

    I could never get sick of the mandarine orange flavor. It took me through the Leadville 100 a couple years ago and I'll be using it again for my next 100 in a few weeks. Big bag makes it easy to scoop from with the simple (included) measuring cup. Perfect if you have an aid station that you'll see a couple of times during your race as you can just leave the bag in the drop bag. Also, great for training/filling water bottles before leaving the house. Never has upset my sensitive stomach. My go to/don't think twice endurance racing and training fuel!

  2. Good tasting, balanced endurance drink 5 Star Review

    (Submitted on 12th Mar 2016)

    I have been using Tailwinds for 2 years now. I have found this to be an excellent endurance fuel. I trained for a full Ironman using Tailwinds and never had any GI problems. It's very well balanced with Carbs, Sodium, Potassium and Magnesium. It also has a nice flavor. I am particularly fond of the Mandarin Orange. I would highly recommend this product to any athlete who is looking for a good endurance fuel! I'm using it currently for my half Ironman training during my swims, bike and run. It's great for all distances!
    Also, the company always writes a little note of inspiration on the outside of the bag. I always like this little gesture. Seems like a great company!

  3. Never Felt Better During Runs! 5 Star Review

    (Submitted on 8th Mar 2016)

    I've been using Tailwind for about 4 months now and definitely have not been disappointed. Like everyone else, I've been through gels, chews, other electrolyte replacements, and whole food products looking for something that would sustain me during a long run and also be easy on my stomach. I decided to start using Tailwind while ramping up to a 20 mile mountain run and must admit I was a little skeptical about all the glowing reviews out there, but it turns out there was no need to be!

    I've used this product on long runs (my "long runs" are only up to about 16 miles), that 20 mile mountain run, and a trail half marathon with great results. I've felt strong(ish) throughout the runs and my stomach has not given me any issues!

    One thing I noticed is that 3 scoops versus 2 for more intense or long efforts definitely makes a difference. I was feeling sluggish on some longer runs with the 2 scoop method, but found 3 scoops largely knocks that problem out!

  4. Saved my Ultra Running 5 Star Review

    (Submitted on 4th Mar 2016)

    Love this product. Being an ultra runner, early on in my running career I was having difficulty with nutrition during my 50k, 100k, 50 and 100 mile events. I was not able to eat enough or keep solid foods down which proved to be detrimental to running fueled and completing events. As I grew frustrated, a teammate introduced me to tailwind. I was reluctant to try as it's description to me just sounded to good to be true. After months and continued struggles in my events I finally decided to take the plunge in Tailwind. Begun gradually using it during training and finally converting to just totally using Tailwind in all my events and seeing an amazing transformation in my abilities to run fueled, feeling strong and running well. The logistics of using Tailwind are minimal for a runner, crews and pacers to support in an ultra event. I am very pleased with this product and happy I took the plunge. I swear by Tailwind.

  5. Believe the Hype 5 Star Review

    (Submitted on 2nd Mar 2016)

    OK, so I am generally a little suspect when everyone is raving about something new - feels like a bandwagon effect. However, there are exceptions and I think Tailwind is one of them. My single biggest complaint with other options is by the time I get to the back end of any long haul race (50 mile, 100K, 100 mile, etc.) I almost cannot choke down anything. Not so much gut issues just plain sick of the taste and texture. With Tailwind those later stages are as easiest as at the start, light, clean and quickly consumed. The texture is ultimately like water, cannot argue with that. Lastly, the electrolytes "embedded" solves the problem of having to choke down a pill late in a race. Love this stuff, incredibly nice and service oriented folks who are so nice to work with. I wish them continued success, stay the course and your fans will stay with you TW!

  6. It works 5 Star Review

    (Submitted on 2nd Mar 2016)

    It's easy on the body, easy on the budget and it just works. Looking forward to my first event and Tailwind will be in the bottle. Give it a try.

  7. Highly recommend 5 Star Review

    (Submitted on 1st Mar 2016)

    I've told all my friends and family, regardless of distance or sport...use tailwind. All have come back with nothing but good things to say and of course I won't train or race without it.

  8. Sooo much better than gels... 5 Star Review

    (Submitted on 29th Feb 2016)

    I'm an experienced marathoner and endurance athlete. Nothing beats Tailwind for staying down and fueling you forward. Who out there has tried to choke down a gel at Mile 22 and then felt sick for the next 3 miles while things settle down? I NEVER have that experience with Tailwind. It is my go-to fuel for distance running or biking. Thank you for creating such a great product!

  9. Love this stuff! 5 Star Review

    (Submitted on 27th Feb 2016)

    I'm just getting back into cycling and at 54 years old I need all the help I can get! I'm training for the BP MS 150 and I believe Tailwind is huge help in meeting my goal of completing the two day ride. And it tastes great too!

  10. LOVE IT 5 Star Review

    (Submitted on 26th Feb 2016)

    Mixes EASY, used at 50k with no food after the starting gun. Tastes great too

  11. So far so good.. 4 Star Review

    (Submitted on 26th Feb 2016)

    Nursing and using it for long runs and speed work to stay hydrated. Taste great and easy mix. My only complaint is scooper is large and doesn't fit mouth of water bottles.

  12. Endurance OCR fuel: Never stop 5 Star Review

    (Submitted on 25th Feb 2016)

    Mixes quick and easy, unflavored variant has just a hint of a pleasant taste to it and is otherwise not distinguishable from water, zero issues but additional power - great product!

  13. Great for triathalons 5 Star Review

    (Submitted on 23rd Feb 2016)

    Great product during triathlons, I definitely feel an energy boost from it. My favorite is the Mandarin orange, my wife prefers the caffeinated. The product is as advertised, easy on the stomach and never a GI problem. I enjoy it during my pool swim drills, in addition to the energy buzz, the Mandarin orange gets that chlorine taste out of my mouth - very refreshing. I take a couple sips as my reward for completing each swim drill set.

  14. The best fuel, period. 5 Star Review

    (Submitted on 22nd Feb 2016)

    I've used tailwind for a year now and all I can say is that it works, and it works well.

  15. Florida ironman 2015 5 Star Review

    (Submitted on 21st Feb 2016)

    Did Florida Ironman 2015 with no distress as only fuel. Will use in concentrated GEL form as mixing powdered ziplock baggies into triathlon BTA (between the arms) bottle is a miserable chore throughout the race. MY FUEL OF CHOICE.
    PS: Berry caffeinated works its MAGIC around the 9-hour mark!! -TIM OUTTTTTT

  16. Everything I hoped for 5 Star Review

    (Submitted on 18th Feb 2016)

    Keeps me fueled on my long runs and workouts without upsetting my stomach. Tastes great and will definitely be buying more!

  17. Essential equipment! 5 Star Review

    (Submitted on 13th Feb 2016)

    Where are you during training or a radar without your favorite pair of socks, a fresh new pair of shoes, or a lucky bracelet or hair tie? They give you piece of Mind and that boost you may or may not be looking for along the way. Just like those pieces of essential gear, I consider tailwind a must-have for the long haul training days and always on race day. Always a happy gut, always feeling fueled no matter the mileage, always delicious, and always such stellar customer service- it's like every scoop comes with your own cheer squad with the awesome employees at Tailwind- I'm looking at you, Molly and Rocky!

  18. Tailwind Lets Me Go the Distance 5 Star Review

    (Submitted on 11th Feb 2016)

    I've trained with Tailwind for over a year now and still haven't got sick of the flavors or had stomach issues. I've ran with it in my hydration vest for distances up to 50 miles, supplementing with aid station food along the way. It will be with me as I tackle my first 100 miler this Fall.

  19. Best endurance fuel by far 5 Star Review

    (Submitted on 9th Feb 2016)

    I was recently diagnosed with hypoglycemia and have been searching for an endurance hydration fuel that doesn't have fake sugars that alter my blood sugar level. Tailwind had exceeded these standards and helps me go longer without any sugary crash. Love it and continuously recommend it to fellow runners and yogies.

  20. Simple and Complete 5 Star Review

    (Submitted on 8th Feb 2016)

    Great, fantastic and easy. Love using this for those long bike rides to mix it up from just water. Tastes way better than other sports drinks I've tried and doesn't make me feel sick (like some brands have in the past). Used for long races on the bike, I wouldn't go any other way!

  21. Best Endurance Fule 5 Star Review

    (Submitted on 3rd Feb 2016)

    Best fuel I have ever used....ran 100 miles without stomach upset and with minimal fatigue.

  22. No cramping or bonking 5 Star Review

    (Submitted on 2nd Feb 2016)

    I used Tailwind for my first 12 hour solo MTB race this past weekend. Been using it for training for two months. Had three bottles of TW on me for the first lap, and just tossed the empty at each lap pit stop (10 mile, 1,100 foot laps). Grabbed three more at lap four... and so on. Never cramped. Never bonked. Took second in my age group. Never close to cramping or bonking. Amazing product.

  23. Works great! 5 Star Review

    (Submitted on 2nd Feb 2016)

    Love the product and how I don't rely on sport gels to get me through long runs.

  24. Always on top 5 Star Review

    (Submitted on 30th Jan 2016)

    Tailwind works all day, every day, any time you need endurance nutrition. No reason to try anything else.

  25. has been great for 20+ mile runs 5 Star Review

    (Submitted on 26th Jan 2016)

    This is by far the best sports drink product that I've used for long runs. I have had a pretty sensitive stomach for any runs over 4 hours, and tailwind has helped that immensely. Personally, I like to supplement it with food just to have something in my stomach.

    My personal method - I've done this the past 3 weekends on my long runs (above 20 miles and around 4 hours) - I bought a large bag of unflavored, then a few caffeine and lemon flavor. I find a nice mix (I don't want a lot of caffeine, rather a consistent low dose) - usually 1 scoop of unflavored, 1.5 of a different flavor or caffeine. I mix this with about 750 ml of water - any less, and it's too sweet for my taste. 750 ml has been the magic spot (there are great 750 ml soft flask that fit great in my salomon vest).

    I go through one of these - about 250 calories - every hour. I supplement this with a bit of food just to have something solid in my stomach - personally, a 200 calorie package of cliff blocks is enough (there's around 8 in there so just eat one periodically). I haven't had any issues overloading my stomach OR feeling like I need more calories. It's been about spot on!

    The unflavored has a nice taste to it, I also liked the lemon, berry and orange. I was mixing 2-2.5 scoops with only 500 ml at first and it was definitely too sweet for me.

    I'm hoping it will really pay dividends in a few upcoming ultras!
