In Shaun White's early days riding snowboards, the sport was so new that his mom was still getting the hang of things after a lifetime of skiing.
Among Cathy White's rules: If Shaun, his brother and sister wanted mom to accompany them down the mountain, they had to ride ''switch'' — backward — so she could keep up.
That, in part, is how a snowboarding champion was born.
''All winter, we rode switch, all day, every day,'' said White, the three-time Olympic gold medalist. ''We're falling and figuring it out. By the end of the season, I was so proficient at riding switch. It was a real gift my mom gave me.''
Though snowboarding loves to flaunt its massive jumps and daring flips, it's the ability to spin four ways — riding forward and backward, then spinning either clockwise or counterclockwise from either direction — that is considered one of the sport's holy grails.
When the medals are handed out at the Milan Cortina Games, the riders who do this the best — or at all — will almost certainly be wearing them.
It's as difficult as it is underappreciated by casual viewers or people who've never tried it. Chloe Kim essentially spent four years mastering this art in the leadup to the Beijing Olympics. Her ability to pull it off under pressure was key to her second gold medal four years ago.
Scotty James also leans into the so-called ''technical'' side of riding. The Aussie, with Olympic silver and bronze medals, upped the ante at this year's X Games when he became the first rider to land consecutive backside 1440-degree jumps — one riding forward, the other riding switch. ''Backside'' means starting the spin with your back facing down the hill.
