Krasnaya Polyana, Russia (SportsNetwork.com) - Marit Bjoergen won gold to lead Norway to a sweep of the medals in the women's 30-kilomter mass start event Saturday at the Sochi Olympics.

Bjoergen finished the race with a time of 1 hour, 11 minutes, 5.2 seconds, beating Therese Johaug by 2.6 seconds for gold in the final women's cross- country skiing event at the Sochi Games.

Kristin Stoermer Steira crossed the finish line 23.6 seconds behind Bjoergen to complete the Norwegian podium sweep. Finland's Kerttu Niskanen was 1:21.7 in back of Bjoergen for fourth place.

With her performance on Saturday, Bjoergen tied the Winter Games record for most career medals (10) and golds (6) by a female Olympian. She earned three gold medals in Sochi, winning an individual title in the skiathlon while also helping Norway take the team sprint event.

Poland's Justyna Kowalczyk, a five-time Olympic medalist, won gold on a broken foot in the 10-kilmoter classic event earlier in Sochi, but she couldn't fight through the injury on Saturday. The 2010 gold medalist in the 30-kilometer event, Kowalczyk dropped out of the race before the halfway point.

Elizabeth Stephen had the best finish for the United States, finishing 24th.

Canada's Brittany Webster came in 46th place.
