    Great for races and early morning runs

    Posted by KK Hoey on 23rd Apr 2019

    I use Tailwind on nearly every run, and just purchased my third bag of each the regular and the caffeinated versions. I love the caffeinated version for extra long runs, early morning runs, or distance races. There's nothing quite like hitting the 75% mark where everyone else is hitting the wall, and the caffeine is hitting your system right when you need it! Tailwind has a great flavor, I love that I can tailor it to exactly what I need for the day, and it's easy on my stomach.

    What I need to get the job done

    Excellent product. Tastes great and doesn't cause me any GI issues. I believe it gives me the fuel and push I need during my long runs and races to perform at my best level. I'll bring my shoes and Tailwind.. Ready, Set, Go!

    So smooth

    Posted by Drew on 27th Mar 2019

    As an long distance runner, I struggled with hydration drinks that I could take with me on long runs, that wouldn’t upset my stomach. After trying more than half a dozen alternatives, a friend keyed me onto the Tailwind product.
    For nearly a year, I have been using the Endurance Fuel for my long runs and my 50K, or longer, trail races. I won’t use anything else.

Caffeinated Endurance Fuel

$38.99

Caffeine kick!

Caffeinated Tailwind meets all your calorie, hydration, and electrolyte needs just like you'd expect, plus it adds 35mg of caffeine per 100 calories. Caffeine is proven to significantly enhance high-intensity and endurance performance.* Raspberry Buzz, Green Tea Buzz, and Tropical Buzz available in 50 and 30 serving bags, as well as 200 calorie stick packs.

Nutrition Facts

  • Caffeine boost when you need that extra kick
  • 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 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.

Usage is similar to regular Tailwind except that we recommend limiting continuous use to 6 hours or less to avoid building up a high concentration. Each scoop contains 100 calories and 35mg of caffeine. 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.
