If you don't love it, we pay your entry fee.*

It's simple: If Tailwind doesn't make you stronger, happier, and less stressed during training and at your next event, we'll pay your entry fee.*

Just order the Tailwind Challenge pack - four 50 serving bags bundled at a discounted rate - train with it, race with it, and if it doesn't blow you away, mail us your race entry fee receipt for a refund.


*The fine print: You knew there'd be some! Entry fee reimbursement is limited to $170 maximum and you must start the event to be eligible for reimbursement.
The purchase must be at least 6 weeks prior to the event so you have time to train with it.

If Tailwind just didn't do it for you, we'd like to hear about it. Send a little description of your experience along with your entry fee receipt and evidence that you trained adequately and started the event, and we'll process a refund.*

  • Each serving is 100 calories. For endurance workouts, mix 2-3 scoops per 500ml 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.
