Jacobellis four-peats in Snowboarder X

It didn't take long for Lindsey Jacobellis to build an untouchable lead on her way to a Snowboarder X four-peat Saturday. Five seconds into a six-woman final, after Jacobellis grabbed the holeshot, Canadian Dominique Maltais wiped out, forcing the rest of the field to swerve around her.

And just like that, Jacobellis was gone. Her lead grew to nearly 100 yards a third of the way down the course; she even had time to scrub her speed in the name of caution. The field slowly narrowed the gap, but she still cruised to her seventh gold medal in nine years.

"I didn't even see [Maltais] go down," said Jacobellis, 25. "Once I got to the top of the butter box, I looked back and was kind of shocked that no one was behind me. That's why I threw that little speed check in there, because those rollers got really deep. So I tried to play it a little cautious going into those last bank turns. And then everything was nice on the way home."
