Take the Tailwind Challenge!

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 10% off - 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 $150 maximum, and you must start the event to be eligible for reimbursement. Challenge purchases must be made at least 6 weeks prior to your race 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 started the event, and we'll cut you a check.
