American snowboarder Shaun White, who became the face of the sport by winning three gold medals, said on Saturday the 2022 Winter Olympics would be his last snowboarding competition and that he would retire from all contests.

"I think this will be my, well this will be my last competition too, which is pretty special," White, 35, told a news conference.

White, competing at his fifth Games, had already said 2022 would be his last appearance on the Olympic stage.

White, who won halfpipe golds at the 2006, 2010 and 2018 Games, said knee and back issues had lingered, forcing him to pull out of competitions and miss training.

"It's this and it's that, all these things are major things that brought me to this conclusion," he said, adding that other riders' tricks were getting "heavier and heavier."
