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!

  • 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.

    My Go To Ultra Fuel

    Posted by Andy Farina on 14th Dec 2020

    For many ultra trail races from 31 to 101 miles this Tailwind is my go to race and training fuel! No gut issues, no cramping, plenty of fuel throughout. Find the flavor you like best - mine is the lemon & naked - and you are good to go! Also make sure to test the amount you use during training. The bag offers a good rule of thumb for how much to use. But it varies for the athlete, conditions, and race in my experience. Enjoy! And Run fast & long!

    One of the better tasting fuels I have used. Love that it dissolves in cool water.

    Best all around

    Posted by Donald G Pizzolato on 10th Dec 2020

    For me the best tasting "fuel" is the one that tastes as close to nothing as possible. In this regard no one can touch Tailwind's "Naked." Only the slightest hint of sweetness and it doesn't get old, even after twenty miles. Customer service is also top-notch. My last bag arrived severely clumped and while it was a simple fix to resift Tailwind shipped me a replacement, free of charge, no questions asked. Customer for life!

    My new go to

    Posted by Do Crazy Stuff on 10th Dec 2020

    My stomach doesn't handle Gatorade on hot endurance races like Ironmans. I use to eFuel for over 10 years and tried Tailwind for my first 100 mile trail run. Tested it out for a marathon first with excellent success being solo fueled on it. Was pleased to find out that even at mile 190 of 200 biking and 60 of 100 running, I was still able to consume it and didn't have to force it down. I've tried the lemon, orange and berry. Lemon is my favorite with Orange as secondary. On 100+ bikes, I do bring extra calories in powerbars, but for liquids this is top notch.

    Endurance Fuel -Naked

    Posted by Dain Eric Cunningham on 10th Dec 2020

    Absolutely the best hydration/fuel product on the market by a wide margin! I love the unflavored “Naked” version, because I can add it to all the unsweetened beverages I already enjoy. Excellent product, all around...
