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. Works wonderfully!

    Posted by Lauren on 30th Aug 2015

    I received my first package of Tailwind a few months ago and never looked back. In the past I have had pretty good luck with gels for lower miles, but for longer adventures they start to really mess with my stomach. I had been looking for something easy to deal with and as natural a possible as opposed to the many processed options out there. This product has exceeded my expectations. I like the flavor once I got the right concentration down for myself (currently using Mandarin Orange) and it has never bothered my stomach. It really makes hydration and nutrition easy while on trail...especially on those early mornings when I am in a rush to get out there.

  2. Multi-sport Approved

    Posted by Return Of The Mack on 29th Aug 2015

    Getting ready for my Ironman distance race I was running into some GI problems. Was (and still) use EFS/Carbo Pro but I found these were upsetting my stomach. Roadie friend suggested Tailwinds. Haven't been disappointed yet. Using for all my long training days without issue. Still will supplement with a few blox and/or salt tabs over the 11+ hour race but minimally. Would use for all my training but product is pricey so I try to keep it for max needs.

  3. Perfect!

    Posted by Unknown on 29th Aug 2015

    I was looking for a new nutrition for long runs and most of my running mates told me to use Tailwind. No stomach bonk, salt included, all in one ! And indeed, nothing to say! It just worked perfectly! Just did 100km and use Tailwind and few gels all the way! Really great stuff!

  4. Simply works

    Posted by RC on 26th Aug 2015

    Like others I struggle with nutrition/hydration during long endurance biking events. I've now done 3 events with TW as my sole source of hydration/nutrition. It works, my cramping issues are gone and I'm feeling fresher longer. Great product.

  5. Great Stuff!

    Posted by Lori Foringer on 24th Aug 2015

    I was hesitant to buy at first, I'm not a fan of overly sweet drinks/food, especially when running. Then during a 50k, when I was unable to convince myself to eat, nothing looked appetizing, i realized that I needed something to help me.
    So I tried lemon flavored. I was happy that the taste wasn't overly sweet. Better yet, it worked! I ran a trail marathon, followed a week later by a 50k, with absolutely no bonking. The clincher was this weekend. I ran a unsupported 30 mile training run on the Cloudsplitter course (in prep for my first 100k there in 6 weeks). Worked perfectly. I never felt hungry, and I ran strong the entire time. Thank you for a great product that delivers as promised!

  6. First 50k and in LOVE

    Posted by Shira on 24th Aug 2015

    I was getting ready for my first 50k and realized i was in dire need of a new aid for my water. I chose Tailwind after many friends pointed me in the direction. Boy am I happy about it. I mixed it with my water in my bladder and froze it the night before. Race day was slated to be particularly hot. I ended up going through 5 full bladder refills of Tailwind at aid stations. Absolute life saver. Since this race I've supplemented all of my triathlon training with it too. Couldn't be happier!

  7. Get Naked

    Posted by Unknown on 24th Aug 2015

    I'm on my third bag of Tailwind and have used it for all my longer training runs and races, including a trail 30k that, because I'm a snail, took 5 hours. I need nothing else when I have Tailwind in my pack, and now that I've switched to Naked (had Berry for my first bag), I don't really even have the plain water cravings after I've been drinking it for a few hours.

    It's what I'd been looking for for years. No more Gu/Beans/Bloks. No more upset tummy. No more bonking. Even my dog drinks it when he's running with me! :) In fact, Tailwind might have saved a dog's life on the trail this weekend after she overheated and was in dire need of fluids. I stayed with her and filled her up with more than a liter from my hydration pack until she was recovered enough to get back to the parking lot with her mom.

  8. Best Endurance Fuel I've Found

    Posted by Jesse Chula on 24th Aug 2015

    I used the mandarin orange flavor of tailwind nutrition this past weekend at the HotHot100K relay in Kentucky and it kept me fueled and topped off all day. I completed 40K on the day with multiple hours of downtime/rest in between laps of a tough, hilly, 10K loop. I used 2 scoops of tailwind in a 21oz handheld and never got close to the 'bonk', even towards the end of the day (our team of 3 total runners finished the relay in 12 1/2 hrs). Tailwind never upset my stomach or caused any GI issues.

    I also never had to take gels or chews during my event but did consume solid food in between breaks as my team members were completing their laps. I highly recommend tailwind nutrition to any endurance sport participant.

  9. Surprisingly Good Stuff

    Posted by Dan Savage on 23rd Aug 2015

    I have been looking for a more simple way to keep myself fueled for long runs. Before trying TW, I had done several other fueling methods including using gels and other supplements from Hammer , and also trying UCAN..Not here to knock either product, they both have products that worked well, but I just always felt awkward having to carry additional stuff.

    My routine for a long run on a Sat morning is to start out by drinking an Isagenix vegan shake 45 mins before running, then during my run I've done:

    1.) With Hammer I was carrying my HEED for hydration, gels to use 1 every 45 mins, taking Anti-Fatigue tabs every 30-45 mins, Perpetumum (sp?) to use 1 every hour and SaltTabs to use 1 every 30-45 mins in warm weather on my long runs. This involves hauling a lot of stuff. Not a fan.

    2.) With UCAN I would take 2 scoops before running with my vegan shake, but they also recommended taking more every 5-8 miles which required me to pack it and carry it, plus carry what I was using for hydration, plus I still needed SaltTabs for warm weather runs & would use anti-fatigue tabs from Hammer too. Still a lot of stuff to haul around..

    The past two weekends I have been trying out Tailwind. I still did my normal vegan shake first, but then on these runs I just took Tailwind only with me for a 15 mile run last Sat and a 17 mile run this Sat - nothing else. It was so cool to have hydration and nutrition all in one pack.

    I felt crazy good during both runs and never once felt like I needed the other supplements I normally take during running. I am totally stoked with the results I have experienced so far! If I feel the same way next weekend after my 20 miler long run, I will be converting over to Tailwind. Needless to say I've quite a great experience so far with the product and I love not carrying all the rest of that stuff!!

  10. I've used a lot of different products but.......

    Posted by Creg Jackson on 22nd Aug 2015

    I'm been an endurance athlete since the early 80's. You name it, I've probably tried it. Keeping it simple and not making me want to puke after 6 hours is important. Measure it, shake it , drink it. My first 100 mile mtb race using Tailwind and I was pleasantly surprised. No bonk, no stomach upset and my wife said I was actually a human being at the end (which is HUGE) was the real test of truth.

    It's all I use now, thanks.

  11. Letting me go Further!

    Posted by Justin on 22nd Aug 2015

    Since I started using tailwind, I have been able to run further without worry of how to get the extra fuel I need. Prior to Tailwind, I had gut issues do to supplements being to sweet. With Tailwind I have not had any issues and use it now for all runs and to help me through bootcamp workouts. Definitely passing the word to all fellow runners!!!!

  12. Finally, something I can use to fuel

    Posted by Paul Maness on 21st Aug 2015

    I have had lots of GI issues running, this is problematic as I run lots of ultras. Last spring during a 50 miler, I got sick, threw up everything in my stomach, miles 28-34 were a struggle trying to re hydrate and get some calories. At that point I started downing 2-3 cups of Tailwind every aide station, not much later I perked up and even ran my fastest mile at mile 43, sub 7 min. Now I fuel on it on my long training runs and am not as worried about my next 50 coming up next month, they are using Tailwind. Thanks!

  13. Awesome

    Posted by Andrew M on 20th Aug 2015

    Good stuff! No stomach issues, keeps me going all day long.

  14. Amazing fuel and amazing taste

    Posted by Mallory BL on 18th Aug 2015

    I've tried so many products over the years to fuel my runs and honestly this has worked the best for me. I like the Mandarin Orange flavor and it has worked like a charm. It powers me for long runs and has also been great for some extra calories during speed workouts. I love Tailwind!

  15. Say goodbye to gut rot!

    Posted by Chris S on 18th Aug 2015

    I have been training to two upcoming Ultra's and continued to have GI issues on 4-5 hour training runs. A friend that I ran with recently uses Tailwind Nutrition and suggested that I try it. It took me three attempts to dial-in the best way to use Tailwinds: first try I began drinking it immediately within my first hour of running. That was a mistake. 200 calories in the first hour was too much for me to digest since my tank was already full from breakfast. Second attempt was a shorter 8 mile run in which I drank half a bottle (or 100 calories) at the half way point. That worked pretty well. Thrid attempt was the best: 5 hour training run on Mt.Hood. I had my hydration bladder full of water and two 24oz bottles in front of my hydration vest. I sipped water for the first hour. I then consumed Tailwinds religiously for the next four hours - one bottle per hour/200 calories each (several streams to refill). My conclusion was this: it worked better than expected. I'm glad I took the time to re-calibrate my hydration strategy and figure out how best to use this product prior to my events next month. No gut rot and it sustained me for five hours. I was a bit hungry towards the end, so I either need to amp-up to 300 calories later in my runs or incorporate some food. I love this stuff and the way I feel long into my runs. NOTE: If anyone is interested in a drawer full of gels, bites, salt sticks, etc, let me know. I don't need them any longer!!

  16. Amazed!

    Posted by runn3r on 17th Aug 2015

    Just finished my first race using Tailwind (orange); been training with it for a couple months now. Race was a 50k trail ultra, 12,500ft elevation gain, humid and 90 degrees.

    Tailwind was AMAZING. Great flavor, easy to mix, ample sodium (which i've struggled with), and no stomach issues!

  17. Gets me to the finish line with a little left in the tank.

    Posted by Matt Eggleton on 17th Aug 2015

    I've been using Tailwind exclusively for a bout a year now for endurance mountain biking. I use it on any ride over one hour (including training rides). When I first starting using Tailwind I thought I needed to eat bars or sandwiches along the way -- I was wrong. I've learned to "Trust the Tailwind" -- it will get me through. I just rode a very rugged race this past weekend -- over 8 hours and 30 minutes in the saddle. Six scoops of Tailwind with every fill of my 70 oz Camelback met my energy needs, and kept me from cramping in the heat.

  18. Only Tailwind in my Hydration Pack

    Posted by Matt on 17th Aug 2015

    Used gels and blocks and other sport drinks for my longer runs before finding out about Tailwind. I really wanted to find something different because the taste of the blocks and gels just was not cutting it. A friend of mine who runs serious miles told me about Tailwind and I took his advise and ordered the orange and naked. In the package, which arrived in blazing speed, contained a nice hand written note, tattoo, sticker and a sample of the lemon. I have used the Tailwind for my long runs exclusively now and have felt great. The taste is not over-powering at all and makes it easy to drink during long hot runs. My stomach has been good throughout the runs and even after the run.

    Thank you Tailwind Nutrition!

  19. Good, steady energy and makes my stomach happy

    Posted by Liz on 15th Aug 2015

    Training for my second marathon and switched to Tailwind because my stomach couldn't tolerate another gel, chew, or bean. Tailwind is refreshing and not overly sweet. Usually if I drink other sports drinks, I have to have water as a chaser because the sugar makes me thirsty. Used it for both a sixteen and a twenty mile long run (so far) - no bonking. Energy was nice and consistent. I particularly like the lemon and plain, but the berry was pretty good. Customer service is excellent and I've never met a more enthusiastic group of people.

  20. Tailwind works

    Posted by marchant wentworth on 12th Aug 2015

    Tailwind works to provide the extra energy to keep on going -- gives you more gas in the tank without giving you gas elsewhere. Besides, John Marsh of Road Bike Rider likes it. As a long time roadie, I trust his judgement in these matters.

  21. Wow - 2 for 2

    Posted by David Boudreau on 11th Aug 2015


    I normally supplement long runs with salt tabs and real food. I've found the salt tabs work very well to combat muscle cramping and general lightheadedness. And I enjoy real food as a way to control the upset stomach I often get from sugary snacks.

    During the Vermont 100 earlier this summer I grew weary of the salt tabs and I tried Tailwind. It was amazing. The weather changed from cool and damp in the morning to sunny and warm in the afternoon and my body had difficulty adjusting. I felt a bit lightheaded and the early signs of cramping as the heat intensified. And I had taken too many salt tabs to continue with salt tabs alone. The next aid station during the run had Tailwind available so I gave it a try before things got bad. To my surprise it was a huge help! My brain fog eased and the early signs of cramping never materialized. I continued to supplement with Tailwind with about 20 oz. every two hours or so. And I do believe this helped tremendously with the finish.

    I bought Tailwind after the run and have used it a few more times since.

    This past weekend I was able to complete the More and More Difficult trail run in New Hampshire (32 miles with 14,000+ feet of elevation gain) with real food and Tailwind as my main electrolyte replacement. Again, I did not cramp and the general fog of endurance running never set in. I was able to come in with a 14 hour and 18 minute finish.

    Very happy with the product and will continue to supplement with Tailwind!

  22. Hits the Spot

    Posted by Phil N on 10th Aug 2015

    No ultra experience with TW but 14mile trail run worked well. <Naked> has enough flavor to make it interesting and thirst quenching but not too filling.

  23. All Endurance/No Stomach Issues

    Posted by Unknown on 10th Aug 2015

    Not only is Tailwind Mandarin Orange lightly and pleasantly flavored, but it does not upset my stomach - which virtually every single other product I have tried has done. I ran a challenging 25k race this weekend solely on Tailwind and never felt better!

  24. Truth in Advertising

    Posted by Liz on 10th Aug 2015

    This product is as Tailwind advertises.
    I've been an ultra-distance runner for 30 years, and Tailwind simplifies my nutrition during both training and racing. I still use "real food" and gels occasionally for variety, during longer runs or races, but this need has been cut by at least 75%. Since switching to Tailwind, I've had no stomach issues, and only occasionally need additional salt in hot weather, to keep my leg muscles from cramping.
    I only wish race directors here in Oregon would use Tailwind as their sport drink at aid stations. It was a relief to finally run one race which used Tailwind: San Diego 100.

  25. En Español. Tailwind es lo mejor!

    Posted by Chris on 7th Aug 2015

    Desde que uso Tailwind dejé de padecer dolores de estómago en mis largas carreras. Puedo correr por horas en climas cálidos y frios sin ningún problema estomacal.

    Son muy fácil de mezclar, los paquetes pequeños son súper para llevar a las largas carreras, los sabores están muy bien logrados.

    Además de ser unos productos geniales, el marketing que tienen es fantástico. Para aquellos que entienden a los corredores, recibir un paquete a tu nombre con una notita personalizada, es lo más!!

    Gracias Tailwind!
