Lindsey Vonn and Boyfriend Kenan Smith Split After a Year of Dating

Lindsey Vonn and former NFL assistant coach Kenan Smith have split after a year of dating, PEOPLE can exclusively report.

“Unfortunately, their busy schedules ultimately took a toll on the relationship,” a Vonn pal tells PEOPLE of the recent breakup.

“It was amicable and they are still friends. Lindsey is laser-focused on her training for the upcoming Olympics and is leaving the country for several months to start competing.”

The star skier, 33, went public with their relationship in a November 2016 Instagram post.

Since then, she and the former L.A. Rams assistant coach stepped out many times, including at the Pirates of the Caribbean premiere in May and at the French Open in June.

Of course, the Olympic gold medalist has the ultimate distraction: training for the 2018 Winter Olympics in South Korea.

“Right now, my motivation and drive are five-times more than what they were in Vancouver (Olympics),” she told PEOPLE recently.

Vonn previously was in a longterm relationship with golfer Tiger Woods, but the pair split in May 2015.
