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.

    Good Taste Great performance

    Posted by Walt Brittain on 25th Feb 2021

    So I have recently switched from Skratch to tail wind after suffering from cramps in 2 Marathon MTB races. Since switcing I haven't had any cramping issues. This is to include the Dirty 130 (130Mile 20K feet of climbing) gravel ITT in the snow.. I reordered last week but my shipment was held up by weather. Yesterday's ride I had no Tailwind so I was back to Skratch. Guess what?? Cramped climbing the hill back into my neighbor hood. I'm completely sold on this product. I feel better and stronger with Tailwind onboard.

    Hint of orange, not overwhelming! Something I could drink all day and not get sick of it. Great way to get calories for all day activity.

    Go-to fuel for training and racing

    Posted by Nick Keenan on 16th Feb 2021

    Easy to mix, great flavor, no stomach issues, and easy 100 calorie scoop portions to fuel my training and racing. I love that they support so many ultra races and look like an amazing Colorado-based small business!

    Very light flavor

    Posted by E.L. on 25th Jan 2021

    It dissolved completely in ~20oz of water so there was no "chalky" last swig, which is nice, and I definitely felt great and hydrated after drinking it (sample ack. However, the whole time I was drinking it it smelled like Orange, but hardly tasted like it. I'm a fan of a subtle flavor, but would still like to be able to taste something. I also felt like it left a weird aftertaste/almost residue in my mouth afterwards that was kinda dry-feeling.

    Mandarin Orange Endurance Fuel

    Posted by Crystal on 22nd Jan 2021

    I love citrus and this is just right without tearing up my stomach on any kind of outing. My 17 year old loves using this product for when he has long days at the tennis court. He says he feels replenished. I too like it for my bike rides. No GI issues. Nice clean simple taste with no overpowering sweetness.

    As someone with a very delicate stomach/gut, this stuff is the truth.

    Posted by Connor Scott on 18th Jan 2021

    Gave this stuff a go off of a recommendation and couldn't be more pleased. Currently, training for my first marathon and Tailwind has been a key component.

    This is best product i’ve ever bought. Not only for running but any exercise...this rips. I even put a scoop in my husbands water when he’s grumpy and he wakes right up! Thanks tailwind!

    Got me through my first 50 mile race!

    Posted by Craig on 6th Jan 2021

    I learned of Tailwind a few years ago and is now my goto fuel for both races and long runs. It's so much better than gels (and tastes better, too!)
