Marit Bjørgen (born 21 March 1980) is a Norwegian cross-country skier and six times Olympic champion from Midtre Gauldal, Norway. She is ranked first in the all-time Cross-Country World Cup rankings with 105 individual victories. Bjørgen is also the most successful sprinter in Cross-Country World Cup history, with twenty-nine victories. One of her most notable achievements was becoming the most successful athlete at the 2010 Winter Olympics by winning five medals, including three gold medals. She also won three gold medals at the 2014 Winter Olympics. With her 2014 medals, she became, alongside Raisa Smetanina and Stefania Belmondo, the most medaled female Winter Olympian. However she has more gold medals amongst her 10 Olympic medals than either of them. She is well known for her endurance, fitness, technical strength, mental toughness, and also her finishing sprints. She excels equally in both classic and skate style skiing, and does well through all distances from the sprint events to the long distance ones.
She is a member of Rognes IL.
Bjørgen initially excelled at the sprint events, and seven victories in that event was enough to give her second place overall in the 2003–04 FIS Cross-Country World Cup season. However, in the 2004–05 season, Bjørgen became an accomplished distance skier.
On 19 March 2006 in Sapporo, Japan, Bjørgen claimed her second FIS World Cup title. Bjørgen led the overall World Cup by 66 points, ahead of Canada's Beckie Scott going into the final race of the season, the 2 x 7.5 km double pursuit. Scott needed to win the race and for Bjørgen to finish no higher than eighth to claim the title. Scott did win the race but Bjørgen came fourth, winning the crystal globe with 1036 points to Scott's 1020. Bjørgen also won the sprint title for the season, 6 points ahead of Norway's Ella Gjømle, making the 2005–06 season the fourth season in a row that Bjørgen has won the sprint title. Bjørgen finished the distance standings in fourth place, 108 points behind Russia's Julija Tchepalova.
