Anni Friesinger has won five Olympic medals; gold at the 1500 m in the 2002 Winter Olympics and the team pursuit in the 2006 and 2010 Winter Olympics as well as bronze at the 3000 m in the 1998 Winter Olympics and the 1000 m in the 2006 Winter Olympics. She managed to qualify for the German speed skating team in five events at the 2006 Winter Olympics: the team pursuit and the individual races at 1000 m, 1500 m, 3000 m, and 5000 meters. However, she failed to win gold in any individual events. In the team pursuit semifinal against the United States at the 2010 Olympics, she fell behind her team members and ended up sliding across the finish line on her belly, but Germany still succeeded in advancing to the final.
As well as being a five-time European Allround Champion and three time, World Allround Champion, Anni Friesinger has won numerous titles in the World Single Distance Championships. Although she originally specialized in the longer distances, she also won the World Sprint Championships in 2007. In this, Friesinger became the fifth skater in history to be a World Champion in both Allround and Sprint disciplines (along with Sylvia Burka, CAN(1976 and 1977); Eric Heiden, U.S. (1977 and 1977); Natalya Petrusyova, URS (1980 and 1982); and Karin Kania-Enke, GDR (1980 and 1982)).
Friesinger has set the world record at the 1500 m distance three times during her career, but the record has since been superseded by Canadian competitor Cindy Klassen. The Olympic record, however—1:54.02—still belongs to Friesinger, and was set 20 February 2002 during her winning run at the 2002 Winter Olympics in Salt Lake City.
