BEIJING — Lindsey Jacobellis is finally an Olympic gold medalist.

Let that sink in for a moment because Jacobellis has been trying for 16 years.

Jacobellis helped make the wild sport of snowboardcross famous. Who could forget her premature celebration as she approached the finish line in the 2006 Turin Games, an ill-timed board grab that sent her tumbling out of the lead? In a way, she became one of the best-known silver medalists of all time.

Now Jacobellis will be remembered as the first American gold medalist at the Beijing Olympics. She reached the top of the podium hours after Mikaela Shiffrin had another stunning early exit on the Alpine ski hill.

Jacobellis rode hard to the finish of the snowboardcross final on Wednesday, beating Chloe Trespeuch of France and covering her heart with her hands as she slowed.

Jacobellis was 20 when she made the mistake in Turin. Now 36 and in her fifth Olympics, she became the oldest U.S. woman to win a gold. The 16 years is also the longest gap between medals for any U.S. woman.

She never stopped reaching for a gold medal.

“They can keep talking about it all they want because it really shaped me into the individual that I am,” Jacobellis said. “It kept me hungry and really kept me fighting in this sport.”
