WHAT IS 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 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.*
 
Select from the following flavours:
Non-caffeinated: Naked, Berry, Lemon and Mandarin Orange
Caffeinated: Tropical Buzz, Raspberry Buzz, Green Tea, Colorado Cola
