To train for the Olympic Games, Shaun says he practiced in a special halfpipe built in the Colorado wilderness. "The only way to get there was a helicopter or a snowmobile," he says. "We had the icing on the cake with basically adding a foam pit so I could then try these tricks into the foam and safely land and then bring it onto the actual wall."

Shaun says he only trained intensely for one or two hours a day. "It's one of those things where I only have a certain amount of energy and focus," he says. "I can't just go free ride it. It's one of those things where I always have to be pushing myself."
