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. Don't Leave Home Without It

    Posted by Mike on 7th Sep 2015

    I have used this product now for several races and a ton of training runs. It is by far the best this I have used, no stomach issues and bonking! It is a true game changer.

  2. IT WORKS!

    Posted by Carol on 4th Sep 2015

    I used this exactly as they say and was extremely satisfied with the results - no bonking, no upsets.

  3. Best Endurance Fuel I Have Ever Used

    Posted by Jim Mann on 3rd Sep 2015

    I have tried every endurance fuel out there, and always had to supplement with either real food or another fuel source. This is the first product I could run on exclusively. It is also the first endurance fuel source that I can run any distance with and not get sick of the taste. Love my Tailwind!

  4. My Tailwind never fails me!

    Posted by Lauri on 31st Aug 2015

    As a triathlete, I'm training 6 days/week, in the Texas heat for a majority of the year! I use my Tailwind on my long bike rides, training runs, and during races. I have never experienced any nutritional issues or bonks. I LOVE this stuff!!

  5. Awesome taste at 105F & ZERO GI issues, period!

    Posted by SteveD on 31st Aug 2015

    This is the *ONLY* endurance (6+ hours) drink ever that does not taste disgusting when the 100F+ pavement heats up your drink to a despicable fruit flavored tea!

    The only drink that I can have 4 bottles of during bike, then 2 bottles more during the run, and finish Ironman distance racing with ZERO GI issues, no cramps, no bathroom blues, just racing fuel to bring your best you've trained months for.

    Don't take any other electrolyte supplement, though I take two bottles of water for every bottle of Tailwind that has 4 scoops on 21oz of water, which is double strength. Also eat solid real food (dates & bananas) to supplement calorie target on bike, and Vega gels on the run for size and convenience.

    It may be for some folks on the pricey side, but having a bad Ironman distance race day costs much more in money and motivation:(

    Finally I can go 10hrs of full throttle racing without doubting my fuel supply! :)

    Kudos to the Tailwind team!

  6. "Coke" in my drop bags...

    Posted by Heather on 31st Aug 2015

    This stuff is exactly what it says: EVERYTHING YOU NEED, ALL DAY. Seriously. I've now completed several training runs, a night 50k race, and a 2-day 100k (Half marathon Friday night, followed by a 50 mile trail run on Saturday). I used TW Naked in my hydration pack all day and night. Depending on the temperature, and how much I was sweating, I adjusted the strength of my "blend", but typically used 3-4 scoops per pack with water, and that kept me hydrated with enough calories & salt for the whole day! At the aid stations, I would grab a few pringles, maybe a PB&J bite and a little coke (cola) at the end of the day, but this stuff is truly a powdery white wonderful miracle! No gut issues, no crash, just constant level of energy. Try it. I did... and I came back and bought more, and will use this stuff to power me through my very first 100 miler!

  7. 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.

  8. 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.

  9. 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!

  10. 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.

  11. 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!

  12. 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!

  13. 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.

  14. 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.

  15. 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!!

  16. 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.

  17. 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!!!!

  18. 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!

  19. Awesome

    Posted by Andrew M on 20th Aug 2015

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

  20. 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!

  21. 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!!

  22. 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!

  23. 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.

  24. 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!

  25. 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.
