Keeping his injury a secret Toutant hit the slopes at the Olympics, he finished last in the men's slopestyle final. In the big air final, Toutant defied his injury and rode to a surprise gold medal, surpassing teammates McMorris and Parrot. After that, he said of his gold medal victory, "I just love snowboarding so much, and I've been through so much lately. A couple of months ago, I couldn't even snowboard, so it definitely feels great that I'm able to ride at my best and to put the tricks down. To be able to show up and to show the world what I can do is just awesome." The victory made Toutant the first men's big air champion in the Olympics, as this was the event's debut at the games.
