Marit Bjoergen wrote herself into the history books as Norway completed a clean sweep of medals in the Winter Olympics women's 30km cross-country.
The 33-year-old claimed her third gold medal of the Sochi Games and the sixth of her career to make her the joint most decorated female Winter Olympian in history, matching the six golds won by speed skater Lidia Skoblikova (USSR) and cross-country skier Lyubov Yegorova (Russia).
Bjoergen finished 2.6 seconds ahead of compatriot and World Cup leader Therese Johaug, with Kristin Stoermer Steira, competing in her third Games, claiming her first individual Olympic medal to complete the podium.
"It's incredible," said Bjoergen afterwards. "We're all Norwegian and we're all on the podium.
"This has been a goal for me for a long time. I thought the 30k would be hard but I've felt very good in the last days."
Austrian Mario Matt also moved into the history books as he became the oldest alpine skier to win an Olympic gold medal, triumphing in the men's slalom.
Matt, 34 years and 319 days old, overtook the record previously held by Norway's Kjetil Andre Aamodt, who was 34 years and 169 days when he triumphed in the men's super G at the Turin Games in 2006.
