In order to win the contest all you have to do is answer the question "Why do you train?" in 140 characters or less. Whether your do it for your health, to win a big race, or you're simply addicted to exercise, no answer is wrong. Submit your answer on the contest entry page before July 22nd for your chance to win. Only U.S. and Australian residents are eligible.
And don't worry if you don't take home the first prize. The other prize packages are great too. For instance, the second place prize is BMC Roadracer SL01 and a 2XU gear package. The third, fourth and fifth place winners will also be hooked up with some sweet compression gear and BMC memorabilia.
Checkout 2XU on Facebook for more information and good luck in the contest. I'd personally love to ride with the team or take home some of this great swag.
