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.

    Great product for Ultra's

    Posted by Anil Rao on 1st Apr 2021

    I have been using Tailwind for 4 years now and I haven't looked back. It is my primary source of refuelling for calories and electrolytes and as long as I have consistent drink of 200 calories every hour I seem to do very well in Ultras ranging 50k-100miles. Great product, keep up the good work folks. my fav flavours are orange and unflavoured. Anil

    This is my third order of this product (also 3rd flavor tried). It was first recommended to me by an ultra-runner friend (I am more of a half-marathon runner). I find it meets the claims (no gut bombs; lighter flavor) and is now my go-to for the hydration bottle. I prefer non-caffeinated mixes and am glad Tailwind provides several flavor choices of those. Good stuff!!

    After trying several chews and gels I found this! So easy on my stomach and gives me the nutrition to tackle whatever I'm looking to conquer.

    Great Product

    I have been using 60 to 75 Tailwind when I go on a weeklong bike ride. It gives me the energy to get up each day and ride 65 to 70 miles a day. I won't ride without it.

    Orange Endurance Fuel

    Posted by Jeff Spurlin on 23rd Mar 2021

    This is what I have used to fuel a marathon, a ton of Half-Marathons, and now, an all nnight endurance run! Since I mostly run in the evenings after work, I love having a good option that doesn't have caffeine, and it never bugs my stomach, even when I run on a completely empty stomach (after work, before dinner 6-10 mile runs). You just can't beat this stuff!

    Tailwind is the number one performance drink in my house . Provides a steady sustainable energy source. I had trouble with the highs and lows during long distance runs and Mtn bike rides . No longer , thanks to Tailwind. Works as advertised, a rarity. Keep up the good work y’all !!

    I have been using this product for several months and have enjoyed both the flavor and my body’s ability to process it without any issues whatsoever. Great product and customer support.

    Best fuel for marathon training

    Posted by Brittany on 7th Mar 2021

    I have tried everything under the sun, between GU, chews, waffles, you name it! Everything typically either upsets my stomach or turns it into a brick, and makes racing and endurance running typically uncomfortable. This is definitely a game changer, and after figuring out the ratios to use for my longer runs, I won’t be using anything else! Incredibly happy with this product, it’s a game changer.
