Estonia's Kristina Smigun's became the first to win two gold medals at the Winter Olympics Games when she triumphed in driving rain in the women's cross-country skiing 10-km classical event, starting off the sixth day that will offer up seven more medals.

Smigun, winner of the 15-km pursuit on Sunday, beat favourite Marit Bjoergen of Norway.

French biathlete Florence Baverel-Robert surprisingly won gold in the 7.5-km Olympic sprint, which involves skiing and shooting, while Norway's Hilde Pedersen took the honour of being the oldest woman to win an Olympic Winter Games medal.

Pedersen, who is 41 years and 189 days, took bronze in the cross-country skiing 10-km classical event.

A gold was also all but sealed for Russian figure skater Yevgeny Plushenko, who takes to the rink later on Thursday.

The 23-year-old Russian holds a commanding lead over second-place American Johnny Weir heading into the free skate programme and even his rivals are all but conceding defeat.
