Levi Lavallee, SnoCross Practice

Lavallee once again tackled all four snowmobile disciplines at Winter X but struggled more than he did last year. He mangled his sled (and nearly himself) in Freestyle, fought to a bronze in Next Trick and made the SnoCross final but crashed early. By the end of Sunday, he had one last shot at redemption: Knock Out. Victory never tasted so sweet. (Dave Lehl/ESPN Action Sports)
