Marit Bjoergen wins 15K skiathlon

KRASNAYA POLYANA, Russia -- Marit Bjoergen won the women's 15-kilometer skiathlon at the Sochi Olympics, giving the Norwegian cross-country skier her fourth career gold medal.

Bjoergen pulled away from Sweden's Charlotte Kalla on the final straight Saturday to win in 38 minutes, 33.6 seconds and defend her title from the 2010 Vancouver Games.

Heidi Weng of Norway took bronze.

Kalla and Bjoergen pulled away from the leading pack of five skiers on the final uphill section coming into the stadium, but the Swede couldn't match Bjoergen's strong finish.
