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.

    Excellent product

    Posted by Jeffrey on 28th Apr 2021

    This product has worked great for me. On longer runs, I try to drink every 30 minutes or so and then finish off a 20 ounce bottle at the end of my run. It has ended my issue of having a headache 2-3 hours after long runs.

    So far so good

    Posted by GK on 20th Apr 2021

    Liking it so far! The taste is unobjectionable, keeps me feeling energized through a day-long ride. I really appreciate the reduction in packaging that this offers over bars, blocks, gels, etc.

    Best all-day fuel

    Posted by Scott Jones on 19th Apr 2021

    I started using Tailwind two years ago for ultra running/training and it's taken over my fueling for all other activities. I have stomach issues and no appetite with endurance sports (nothing tastes good and my stomach shrinks when I run) so Tailwind has been the best way to get calories for me. I still don't drink enough while moving but skied Mt St Helens yesterday with only 2l of Tailwind, a handful of Sour Patch Kids and a pepperoni stick... No crash, no bonk and no digestion issues with 6hrs of moving and 5500' of climbing. The lemon flavor is my favorite mild flavor, but the tropical caffeinated ones are also great.

    Endurance Fuel, Orange

    My first time using this during a half marathon. I think it worked really well - provided hydration and energy thru out the race, with a light taste and no GI issues.
