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.

    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!

    Nutrition Made Simple

    Posted by mtnbikej on 6th Feb 2017

    I switched over to TW about 1.5 years ago. I have been a long distance mountain biker for several years. Over the years I have tried different electrolyte replacements via gels and drinks. I always found them to start upsetting my system a couple hours into the rides.

    Heard about TW and gave it a try. I thought how could a bottle replace the solid food I was ingesting. Gave it a try and was surprised by how it worked. There was a short period of getting over the mental brainwashing of thinking I had to eat solid food. In fact for the first 3 weeks of using TW I carried the same pack of Clifbloks and a gel in my jersey pocket as a "just in case". Once past the mental roadblock, it was clear how well this stuff works.

    I regularly do 6-12 hrs mountain bike rides in warm sunny So. Cal. with only TW. No loss in energy. No upset belly. No more hunger. No more cramping.

    I like that no matter the doesn't get difficult to drink. Some drink mixes are just horrible if they aren't ice cold.

    TW has made planning long days on the bike simple. I pack all the TW I will need for the day and remix my bottles as needed.

    You won't be disappointed.

    No more headaches!

    Posted by Sprinkles on 2nd Feb 2017

    No matter how much I seem to hydrate before and after long or hard runs I always seem to get a dull, throbbing, untouchable headache. I was introduced to Tailwind at the Pistol Ultra, as it was their drink of choice on the course. I know they say never try anything new on race day, but I had been wanting to try it and after doing a bit of research I didn't think it would hurt to give it a shot. I ran my first ever 50K that day and felt unremarkable. The next day it hit me - I DIDN'T GET A HEADACHE! I ordered some for myself soon after. Drinking Tailwind during a long run or immediately after a hard speed workout keeps my headaches away. If I forget to have some and I end up getting a headache, I've found one scoop in 8 ounces of water will get rid of it fast. If you suffer from post-workout headaches this stuff is definitely worth a try!
