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. Great product

    Posted by Tom Syre on 29th Jul 2015

    All you need. My strategy for long runs is to have two handhelds: one with 2.5 scoops Tailwind (naked) and one with water.

    No chews, no gels, no pills. Easy and effective.

  2. En Español

    Posted by Gustavo on 22nd Jul 2015

    He usado Tailwind por casi un año con excelentes resultados, he hecho varias competencias cortas y algunas largas como La Ruta de los Conquistadores solo usando este producto y la verdad me ha ayudado muchísimo. Adiós a los calambres.

  3. Wonderfully steady supplement!

    Posted by Elise on 22nd Jul 2015

    i loved the mandarin orange flavor and tolerated it easily through very hot training (bike and run workouts for upcoming triathalon)
    enjoyed trying the berry flavor and will purchase that next! it is almost funny how it really does begin to taste better as you get further along in a given workout!

  4. Just Wow

    Posted by Robyn on 20th Jul 2015

    Love this stuff! First, the flavors. I ordered the lemon, and also received a sample of the unflavored, which I tried first. It's not tart, not sweet, not salty, but somewhere in the middle. The best I can describe is sort of kefir-ish, but not unpleasant. In fact, I may order this as my go-to flavor next time. The lemon was also alright, but in endurance fuel I don't want zing pow zap either, nothing that will pucker my mouth, know what I mean?
    Now to the official stuff.
    This product works wonders. I don't have the sloshing or gurgling in my gut, everything absorbed quickly and efficiently, and I found that my legs didn't get fatigued while running. I have to do my training on the treadmill so I have it set right now at 3* incline for resistance. I'm training for a half marathon and after that for a mini-relay, and if all goes well with my knees will get back to doing a full marathon every year as well as other shorter races. I'm using Tailwind to replace the GU and the electrolyte mix I was using before in my hydration pack. I recommend this product to anyone who has to fuel on the fly.
    A note: I run in bear country. Bears can smell food, I have read, up to 20 miles away. Maybe that was a typo... maybe not. But I've always been concerned about carrying GU because no matter how hard I try I always get that sticky mess on my fingers, my clothes, and I have to pack out the empty packets too. Yes, I'm paranoid, but like I said, I run in bear country. The Tailwind is much neater to use and I do love that it's electrolytes and nutrition in one product.

  5. Perfect fuel for the long haul

    Posted by William Curtin on 20th Jul 2015

    Tailwind got me through a 50 mile run yesterday without any stomach issues whatsoever. Zero headaches, zero nausea. I kept my intake to about 2 scoops/hour, plus a little food (bloks, gels, fruit, peanut butter) just to have something to chew on while I ran. I have been using Tailwind for almost 6 months now, and I absolutely love it and believe in it.

  6. So far, so good!

    Posted by Betsy on 17th Jul 2015

    I'm getting ready for a 200-mile race in a couple of weeks and based on reviews by friends I wanted to give Tailwind a try. Indeed, it has a very mellow (and pleasant) flavor that I think will continue to go down easy toward the end of my race. I just did a 6-hour training run where I normally would take in 5-8 gels, but decided to just use TW. Happy to say there was no bonking!

  7. Great Product!

    Posted by Matt on 16th Jul 2015

    Got introduced to this product from a friend on a mountain bike trip and tried it out. Ordered my own as soon as I got home and haven't looked back since. I've definitely noticed the difference using a dilute solution during outdoor workouts on hot days (I live in Houston) were I sweat a TON. More sustained energy, no muscle cramping or stomach issues. Tastes good too! I like that it contains no colors or other unnecessary ingredients. Will definitely be keeping this stuff on hand.

  8. lots of energy. slightly salty taste

    Posted by Zeke Stanis on 15th Jul 2015

    very good product. I was impressed with the amount of energy i got while using the product. The salty taste was a little over powering. I have to bring another bottle along with me on the run to satisfy the hydration need.

    I would use this on my longer runs and race day. shorter training runs i would go with straight water

  9. Only use TWN

    Posted by Andrew P. on 13th Jul 2015

    It's all I need when out on the trails. For me, it's good for longer runs above 10 miles. I use both the berry and orange and have loved them! Will continue to buy TWN in the future for sure.

  10. Amazing!

    Posted by Dennys on 13th Jul 2015

    Training for Ironman 2015. I've tried other supplements and nothing works like Tailwind. They have a lifetime customer in me!

  11. Less salt more sweet needed

    Posted by Stacey on 10th Jul 2015

    I find the product a little salty tasting which is to be expected since it contains salt but maybe if the flavor was a bit stronger it would help offset the salty taste. Otherwise it dissolves well and my tummy tolerates it well.

  12. It's all you need, minus water.

    Posted by VanLooRunning.com on 9th Jul 2015

    I absolutely love this product. I made the switch over to just Tailwind nutrition at the beginning of this year and can honestly say that it's all you need. I've used it in all of my ultras that range from 50k to 100 mile races. If you ever deal with fatigue or cramping, ditch whatever you have and start training with Tailwind. You WON'T be disappointed!


    Posted by Roby T on 8th Jul 2015

    I had used other fuel, or liquid foods as my wife calls them, and I can say that this is one of the best ever! The easy it mixes and the subtle lemony flavor is great!! Looking forward to use it during my next race.

  14. Rocket Fuel

    Posted by Mike Holmes on 5th Jul 2015

    I started using Tailwind while training for Western States this year on all my long runs and on my 3 ultra races leading up to the Big Dance. It always provided the nutrition and electrolytes I needed for a balanced endurance performance without the problems and issues related to digestion and heat related problems. Great results and ease of use have made it as important as my shoes for my endurance adventures.

  15. Perfect addition to training

    Posted by Alicia on 1st Jul 2015

    Perfect addition to our Ragnar Relay run!

  16. No more cramps!!

    Posted by Mike on 1st Jul 2015

    I was having issues with cramps and a riding buddy suggested I give tailwind a try. I started using the tailwind endurance fuel and haven't had any issues with cramps since. The package showed up two days after ordering with a hand written thank you note and a sample of the other flavor of endurance fuel. Outstanding product with outstanding results.

  17. A great addition to the trail

    Posted by Tim on 1st Jul 2015

    I'm getting ready for some longer and more challenging trail runs this coming summer (Boulder, CO in late June and Mt. Whitney in mid-August) and a good friend of mine recommended Tailwind for some longer runs due to the nutrition content and mildness on the stomach. I got the Tailwind in time for the Boulder trip and used it for runs at Green and Bear Mountain, as well as a great road bike ride from East Boulder to Jamestown (a classic Boulder ride). I had to admit the Tailwind worked great for me and, although I did supplement with a little solid food, I found these longer and more challenging activities much easier to handle with the better nutrition and hydration from the Tailwind. Can't wait to tackle Whitney in August!

  18. This stuff is awesome!

    Posted by Dylan Allen on 1st Jul 2015

    I heard about this stuff from Ethan Newberry (The Ginger Runner), and initially bought some to try out. But even as a skeptic of most products (I'm a personal trainer, and most of my clients don't really need any supplements, or anything but real food really), this stuff has been great! I normally sweat a lot, so for longer events, or even just long runs in the Oklahoma heat, this stuff has been amazing! Good enough that I have actually recommended it to some clients.

  19. Best endurance fuel - Mandarin Orange is awesome!

    Posted by Unknown on 30th Jun 2015

    I have been looking for something to stop the gut bombs. I was doubling over in stomach pain on my last 50 mile race. I have tried mostly every endurance fuel. Tailwind truly changed my stomach issues, especially on long runs. I will be using tailwind at my next 100 mile race (VT 100). Thank you!

  20. Best hyrdation/fueling product out there

    Posted by Keith Hearn on 29th Jun 2015

    I just started using Tailwind and found that its great for keeping hydrated and fueling for my long training runs leading up to my first 50k.
    Really enjoying the naked flavor the best.

  21. Mandarin orange outrageous optimal energy

    Posted by Carol on 29th Jun 2015

    Thanks for the personal touch!

  22. Excellent Choice for Base Energy Source

    Posted by Unknown on 29th Jun 2015

    Used Tailwind Berry on a 200 mile training ride this weekend in preparation for an upcoming bikepacking race. Tastes great, easy on the mouth & stomach, and provided consistent energy and electrolytes throughout the entire ride. Definitely an upgrade from other energy products that I have used. Looking forward to trying some more flavors.

  23. Should be called Tail Hurricane

    Posted by Chris on 25th Jun 2015

    A friend of mine was extolling the virtues of this new drink this weekend on a gruelling, long, hot mountain bike ride. He didn't eat a thing. Meanwhile I was alternating between crashing sugar lows and Choking on cliff bars as I struggled to ride the bike and eat. He finished refreshed and not the emaciated wreck I was with all my muscles screaming. I was convinced. I bought some the same day and tried if for the first time this morning. I set PB's on all segments of my ride and I feel great now without that depleted feeling. Rocket Fuel!

  24. Love this stuff!

    Posted by Jerry Doyle on 23rd Jun 2015

    My training partner ran/biked/swam using Tailwind for a couple of years before I finally tried it. I've never regretted it. I use it for all my endurance activities and just carried two 7 oz. bottles of it while running the Mount Washington Road Race in New Hampshire!

  25. I used this for a warm and humid 70 mile race and it was awesome!

    Posted by Kristen on 21st Jun 2015

    After years of struggling to find the right balance electrolyte tablets, water and real food - often supplementing with unappealing gels - I finally found what I need in Tailwind. I mix it directly in my hydration pack bladder and just sip throughout the run. I don't have to think about taking pills every xx minutes or about packing food to eat. It keeps my energy level up and on an even keel and keeps me mentally sharp. When I get to aid stations in a race, finding food isn't important. If I see something that looks good, I'll eat it. But if nothing appeals to me, I'll just skip it. I don't NEED to eat like I used to. I won't run without it!
    Not only is Tailwind an excellent product, but the customer service is first rate. My orders come very quickly and always with a handwritten note and my name written on the bag. I've received bonus stick packs, stickers and tattoos as well. I feel like a VIP each time!
