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. A drink mix that works!

    Posted by Joe S on 4th Mar 2015

    Pleasant taste, easy to use, ingrediants your grandmother could pronouce and would recognize. No digestion issues, which is important to me as I am sensitive in that area. Are great way to get nutrition into the body while staying hydrated. Really good stuff.....glad I stumbled upon it.

  2. Best Endurance Drink

    Posted by Warren on 28th Feb 2015

    Very happy with Tailwind, and have tried quite a number of products. Pleasant taste (even if water bottles get warm), and no digestion issues. Have done some pretty long rides with a lot of climbing and feel it's definitely helped.

  3. Easy and effective

    Posted by Unknown on 27th Feb 2015

    This product is so easy on my stomach and literally do not need any other nutrition. I do need to combine it with solid food for 50+ miles. But very effective to keep you from falling dehind in nutrition.

  4. One stop shopping

    Posted by Paul on 26th Feb 2015

    After trying all the flavors I have settled on the naked. Although naked says it's unflavored I find that it has just a tiny bit of sweetness to let you know it's there. I have been using Tailwind for over a year and love it. It was my go to supplement for hydration, fuel and electrolytes during my first 12 hour run in July 2014. When they say it's all you'll ever need they were right. It will also be on board for me for Ironman Wisconsin in September.

  5. Finally, a drink mix that works!

    Posted by RChalfant on 26th Feb 2015

    After trying all the rest, a friend informed me about Tailwind. Glad I tried it, it really does work, and no side affects such as bloating or stomach issues during my runs. I will be running Zion 100, Tahoe Rim trail 100, and Wasatch 100 this year, and will use Tailwind Neutral flavor during these ultras. It is by far the best ultra fuel on the market that I have tried, and will be replacing gels, bars and blocks.

    Thanks Tailwind!

  6. Easy on the stomach and gets the calories in.

    Posted by Will Frank on 24th Feb 2015

    Very easy to mix with water. Does not have a sour taste like most other liquid calorie sources. Instead sits well and has a smooth taste. The calories are quality calories as well, that keep you fueled for hours on end. I used the unflavored uncaffinated for hours 1-23 of a 24 hour race and the caffeinated for the final 24th hour as my main nutrition and it fueled me effortlessly. This is a great product if you don't have a crew or form of support during an ultra event. Get the single serve pouches to take with you and you're set! Add water first and then tailwind, no need to shake it up, dissolves into the water for you!

  7. pushes me to try longer distances

    Posted by Brian A Smith on 24th Feb 2015

    Tailwind does for me exactly what it advertises and more. It's easy when its cold outside or the run gets monotonous to want to cut it short and head for the shower. I have found that Tailwind motivates me to keep going because I know I have the fuel to push myself further. I can take my mind off of my physical needs and concentrate on overcoming my mental limitations.

  8. Best way to get calories down the neck

    Posted by Steve on 23rd Feb 2015

    Tailwind really is a one-stop-shop for nutrition on long training runs or races. It's easy to mix and portion (handy cup included) whether in a handheld or a bladder.

    The taste can be strong if you lean more towards stronger mixes like I do, but it is more than palatable. It really does reduce cramps, GI distress and hunger pains at mile 20+ and beyond.

    I have not used it in summer heat yet, but I would expect it would perform just as well, although the taste may get funky in the heat (So I've heard).

    Great product!!!

  9. Why Wouldn't Someone Use this!

    Posted by Andy Farina on 23rd Feb 2015

    Excellent product!! Mixes effortlessly. Fuels super well. Great customer service. And competitively priced! It is kind of a no brainer. Every Ultra Runner I have talked to loves it! Recently, I used it to fuel for an almost 10-hour mountain race and was super pleased. I use it regularly in training for a 24-hour race I am preparing for. Again, I am very happy with it.

    The Lemon flavor is my favorite. The berry flavor is pretty good. Plain is fine too.

    I can understand why any serious runner would not use this product?
    Thanks Tailwind for being GREAT!!

  10. Mandarin is the best all day

    Posted by reuben on 23rd Feb 2015

    I never grow tired of the mandarin flavor. Mixed heavy for long hot days or lighter for colder days, it's still palatable at the end of any long event or workout.

    As I prep for IM France tailwind is my go-to nutrition!

  11. All day really!

    Posted by Todd Evans on 20th Feb 2015

    I have been using tailwind for about a year now. I had the oportunity to test the "all you need all day" theory at a 100 mile race. I used Tailwind exclusively for 27 hours, nothing else except a piece of bacon at an early mornining aide station (I couldn't resist the smell). I was amazed how well I felt throughout the entire run, if I ever felt hungry I added a little more powder to my next bottle and that took care of it. I consumed about 7000 calories during the run, no stomach issues, no bonking, no cramps. I have to say, this is the best stuff I have ever used.

  12. Got me through IMFL

    Posted by Virginia on 18th Feb 2015

    I waited until I finished my first full IM in November to review
    the product. I used tailwind in my training and all through IM Florida. I was too afraid to go completely without food, so I ate a macrobar every hour on the bike and two peanut butter and jelly sandwiches. I did not take a single gel which was always my go to before tailwind. I felt strong and happy and of course exhausted in the end, but I think tailwind got me through it. I did not take it on the run, but I might do that when I return this year for my second IMFL. Thanks for a great product. I recommend it to all my friends!

  13. i love tailwind

    Posted by dewaynne on 18th Feb 2015

    I used it for the 1st time at The Rocks and Roots 50K on Feb 8th. course was mostly ice and ankle deep mud. with Tailwind my energy stayed constant for the entire race, stomach felt fine and I had NO leg cramps. I will be using Tailwind for all of my ultra's and World's Toughest Mudder in Nov. The orange tastes great. 2 scoops per bottle in my Orange Mud Hydraquiver worked out perfect for me.

  14. Testing out for my 50k

    Posted by Chrissie on 18th Feb 2015

    I ordered tailwind based on several recommendations from ultra runners. I have trouble with all gels and most drinks (GI upset) I have used for 5 runs of varying mileage (including a marathon) and nothing but good things to say. Kept hydrated, got calories and no GI distress. I am taking it on an overnight relay this weekend and look forward to good nutrition without the distress

  15. Perfect endurance fuel

    Posted by Brie on 15th Feb 2015

    I recently purchased Tailwind after hearing about it on TrailRunnerNation. And I am pleased to say that it is everything they had said it is.
    I have used it on 7 different long runs now, each ranging from 2-5 hours. NO OTHER FOOD/ELECTROLYTES NECESSARY.
    LOVE it! Makes it so convenient on my long runs to just have this as my fuel instead of carrying a bunch of gels or other food. I am able to put it in my pack & go. I have always been horrible about eating when I'm supposed to & on time, especially taking my electrolytes. Now, I have not had ANY cramping (I usually will), feel energized my entire run, no bonking, & I am even recovering better/faster. I am also never hungry during my runs. I stick to ~250 calories per hour.
    I would recommend this to any endurance athlete & have been telling all of my friends about it.
    Oh & it tastes great! I do NOT like sweet stuff. HATE gels, even though I would still use them. But, this stuff is more savory. Not to sweet at all. :)
    Thank you!

  16. Like it a lot

    Posted by Amy on 15th Feb 2015

    Have had some bloating problems with other sports drinks ... Ordered the berry tailwind and it tastes great and I don't have to eat as much during long training runs. No stomach problems and really looking forward to trying it when the weather gets warmer and my stomach tends to get upset easier.

  17. Tried it, loved it!

    Posted by Courtney Carter on 14th Feb 2015

    I tried Tailwind Endurance Fuel on my 2 hour training run today and it was great! I didn't have time for breakfast, but did not feel hungry or overfull the entire time. It tasted great and I had plenty of energy. I look forward to bringing it on my longer training runs, 50k, and 50 miler.

  18. The best available

    Posted by Bill Packard on 13th Feb 2015

    I have been using Tailwind now for two years, it has greatly helped me improve throughout my training and of course during races as well. Without Tailwid I would never have reached the level I am at today. Thank you for such a great product and service !!

  19. Simplified my race nutrition!

    Posted by Unknown on 10th Feb 2015

    historically had lots of issues with nausea after mile 30 in races...since switching to using Tailwind have had no issues in training or 6 day stage race, my first 100 mile and 100K. Ran all day at SOB100K this last weekend and Tailwind was my go-to nutrition! Don't worry about additional electrolyes anymore! Great product and the customer service is the best!

  20. A real lifesaver

    Posted by Unknown on 10th Feb 2015

    Recently ran the toughest ultramarathon of my life. About 22 miles into the 50 mile race, it was tough for me keep down any solids and was in the middle of a grueling 4 mile climb. Thankfully I had two bottles locked down with Tailwind that helped to keep me going. It was easy on my stomach and let me get to the nirvana that is an Aid Station.

    Beyond that, the customer service is awesome. My last two orders have come in like 2 days and with a handwritten note. Awesome to know that someone takes the time to personalize their work and show a little extra love. Keep it up!

  21. May have found my fueling answer!!

    Posted by Thomas G on 9th Feb 2015

    So far I have used Tailwind on three 20+ training runs with over 15,000' of elevation gain and had exceptional results. I had no stomach issues on any of the runs and didn't feel hungry all day. Not to mention the fact that it powered me through some really tough climbs, extremely wet muddy conditions, and a freezing down pour!!! Very satisfied with this product so far. Oh and the taste is phenomenal not too sweet or heavy, the lemon flavor is very easy to drink.

  22. For Long Distance, Tailwind is the Only Choice

    Posted by Unknown on 8th Feb 2015

    Who doesn't like riding with a Tailwind? When it comes to sports drinks, we have probably tried them all. The best results that we have had have been with Tailwind. If we take Tailwind we don't need Shot Blocks, Gu, or Hammer Gels. Tailwind is all you need for any ride from 30 to 100+ miles.

  23. Use for Strength Training

    Posted by Victoria Lyn on 6th Feb 2015

    I LOVE IT! It keeps me going to perform my HIIT after my strength training. I never feel worn out with this product. I even use it post-workout to help shuttle protein into my muscle cells! I add it to my homemade whey protein isolate shake.

  24. So far so good!

    Posted by Van "Pigtails" Phan on 3rd Feb 2015

    I have only used this product a few times but like it so far. It is light in taste as advertised. I still use a gel before a big climb, but experimenting with fewer calories outside of Tailwind. I am going to use it for the first time in a longer run at a 50K with 8400 feet elevation gain. Looking forward to feeling strong!

  25. Absolutely satisfied

    Posted by Jeremy Hanson on 3rd Feb 2015

    I used Tailwind on my 100 miler this weekend and had absolutely no nutrition or hydration problems at all. I am completely 100% satisfied with this product.
