    So Far, So Good

    Posted by Alex Kinon on 25th Aug 2019

    I had read many positive reviews about Tailwind and decided to give it a try. I have used it in my hydration pack for two Spartan Races: a Super and a Beast. While my experiences with Tailwind only span two events, so far I am very pleased with the results. I have used no other source of calories and I have felt fine. I have also not cramped! So far everything about Tailwind has been positive.

    Truly a great product

    Posted by Aaron on 15th Aug 2019

    I have run a couple 50 mile ultra marathon trail runs using almost exclusively Tailwind for training and race day. I can't say enough about how happy I am to have found Tailwind. I will be attempting my first 100 mile trail run soon and I am confident that Tailwind will help me finish the journey. Thank you Tailwind.
    Also, I have tried several of the flavors and I have yet to find one I did not like.

    Great product but came damaged

    I’ve been using tailwind as my main source of fueling/hydration while training and competing in Ironman events. Love the taste and consistency. My only negative would be that one of the bags was split open on my last order. I was able to salvage most of it but better packaging for delivery would help. Otherwise no complaints.

Endurance Fuel


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!

Nutrition 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.

All Natural and Organic Ingredients
