Endurance Fuel

50 Serving Mandarin Orange

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.

    Great for long distances

    Posted by Deb on 21st Jun 2017

    When I use tailwind for marathons and long bike rides(56 miles and under) I am not hungry until my event is over - most of the time. Love it for my training

    so far so good

    Posted by Kim on 18th Jun 2017

    Just started using Tailwinds upon the recommendation of a sports nutritionist. The flavor is mild and does not cause any stomach distress. So far we have liked this product for performance during work outs as well. I recently used it during a sprint tri and it was great. We have longer races planned for this summer so looking forward to more good results.

    I'm definitely drinking the Kool Aid, um, I mean the Tailwind!

    Posted by Roy Kranz on 9th Jun 2017

    I tend to push my limits, 85 mile hikes without sleep, gravel road races on my fat bike that are over 200 miles long, etc. I have always thought feeling sick about 10 hours in was inevitable. Now I know that is not true. With Tailwind, I no longer have gut rot. What an awesome feeling. Also, my performance is high. I just won the fat bike division at the Dirty Kanza 200, finished 83rd overall out of over 1150 starters and felt great even at the end. This stuff is great. My only complaints are that the bag is tough to re-seal and the unflavored does in fact have a flavor (but it tastes good so it really isn't an issue).

    Easy to drink during endurance races

    Posted by Unknown on 4th Jun 2017

    I've tried several other endurance fuels, but nothing compares to Tailwind. I find this product very easy to drink while riding hard, it goes down easy, with just enough taste to keep you interested, but not too much that after 6 hours on the bike, you become tired of the taste. This product does not make your saliva thick, which is extremely important to me, you don't have time to clear your throat when racing.

    Simply perfect!

    Posted by Kacey E. on 28th May 2017

    I discovered Tailwind while training for my first marathon. The Florida humidity can do a number on you when training during the summer. I don't know how I ever ran any distance without it and I just love the taste of it too. It's tastes clean and light, great in my hydration pack or a bottle. Having sensitive tummy issues, I tried several different combinations and other brands out there but still had issues during and post run with no energy, headaches and stomach issues. Tailwind is the perfect answer. It really does what it says. I'm so thankful I found Tailwind.

    Fuel for 8 hours of mud

    I used this during an 8 hour Tough Mudder event and it worked wonderfully. The taste is light and easy to drink. Never felt hungry or drained.

    This is MAGIC for me!

    Posted by Gael from Boston on 5th May 2017

    Sharing for those who are seeking an alternative to running fuels. I cannot tolerate GU. Very strange as I live off triple shots daily and must have coffee before every run and race, but GU makes me feel completely discombobulated.

    For years, I loved Nuun, but then they changed the formula last year and the worst happened. I prayed to God for the remainder of my run - upset tummy beyond belief and I take great pride in my cast iron stomach. An Iron athlete suggested Tail Wind and it has been a great love affair. Every thing that was said in the reviews are TRUE!

    The powder mixes easily. Initially, I ordered the multi-packs before committing to a bigger package. I can run up to 10 miles without the need to replenish along the way as long as the temps are under 80. I drank a liter of regular water and another with Tail Wind mix. My run was unbelievable. Typically around the 9 mile mark, I can feel the need for fuel, but in this instance, I did not. No crash from the need to refuel came and I felt as if I could have ran another mile. I first thought that my performance was placebo, that I was buying into the hype and so I tried it again on my longer runs as fuel in my bottles several times and same response.

    No tummy cramping, a clean taste, no chalk or power residue, no cramping in my legs during the warmer days and no swelling of my fingers. It's hard to pinpoint, but my run was more focused and at times I felt so good that I had to pull back as I had picked up a significant pace which was too hard for a 15 miler LSD. I was not hungry, but I still ate my fruit snacks and drank my typical smoothie pack during my LSD. Coupled with all of this, I have had some very good results on my runs/races.

    Post runs, for some reason, I am not ravenous for hours. There is no crash, and no lingering soreness. Recovery is great.

    My Highest Recommendation

    Posted by Christopher B. on 20th Apr 2017

    I purchased my first bag of Tailwind Endurance Fuel after a 7-time Leadville finisher (with buckles) recommended it to me. She said it would be the only fuel I would need. Before Tailwind, I had never been able to do mountain bike rides of over 50 miles without dealing with leg cramps. Sometimes minor, but usually severe. I sweat a lot, so my body depletes salt, potassium, calcium, and other essential nutrients rapidly. Since buying Tailwind, I’ve been doing long training rides without cramping. Recently, for my 58th birthday, I mapped a course of 58 miles (90% off-road) that included almost 9K feet of climbing. Two friends joined me that day. One bailed out about 25 miles due to severe cramps. He had water, bars, and gels. The other, a friend that usually out-climbs me, finished the ride, but not without suffering cramping the last ten miles, and me beating him silly on those final long climbs. He was using a different sports drink, bars, and gels. His last words to me that day before driving home were “You sure looked fresh on those last few climbs. I’m going to go home and order some of that Tailwind.” I did feel fresh, and I attribute that to using Tailwind. With four+ months to go before heading to Leadville for the LT100 MTB, I’ve already settled on my nutrition plan. Tailwind!
