Put mildly, halfpipe skiing is no joke. It's a dangerous, gravity-defying, and exceedingly difficult activity for supremely fit athletes, where the smallest of mistakes can result in catastrophic injury. Take it from Dumont, who has plummeted from 55 feet in the air and has even competed with one arm still healing - with 11 pins in it and the other hand fractured, too. Perhaps ironically then, the gold winners tend to be those who make their feats look like a walk in the park. "I think style is, you're doing the gnarliest thing ever and make it look like whoever is sitting on the couch can do it, too," Dumont says.
