Krasnaya Polyana, Russia (SportsNetwork.com) - Despite skiing on a broken foot, Poland's Justyna Kowalczyk easily won the women's 10-kilometer classic cross country race on Thursday for her fifth Olympic medal and second gold.

Kowalczyk finished in 28 minutes, 17.8 seconds to beat 2010 Olympic champion Charlotte Kalla of Sweden by 18.4 seconds.

Norway's Therese Johaug earned the bronze, 9.9 seconds behind the silver medalist Kalla.

Kowalczyk, who won the 30-kilometer mass start race in 2010, posted an X-ray of her left foot on Facebook Saturday that showed a fracture. She was injured last month.

Finland's Aino-Kaisa Saarinen was fourth and Norway's Marit Bjoergen, going for her ninth Olympic medal, finished fifth. Bjoergen outsprinted Kalla to the finish line for the gold medal Saturday in the 15-kilometer skiathlon.

Kalla now has four Olympic medals, including one gold and three silvers. Johaug previously won a women's relay gold in 2010.

Sadie Bjornsen was the top American finisher in 18th place. Brittany Webster was 42nd to lead Canada.
