Born in Schmalkalden, in the Federal State of Thuringia, Germany, Kati Wilhelm started training cross-country skiing as a child in 1983 and was a member of the German cross-country ski team at the 1998 Nagano Olympic Games. In 1999, while attending the Military World Games, she came into contact with biathlon and was hooked on the sport. Her decision to switch to biathlon proved to be a good one. The next year she experienced her first successes including a World Cup victory. Winning gold medals in the 7.5 km sprint and the 4 × 6 km relay and a silver medal in the 10 km pursuit, she became the most decorated biathlete at the Salt Lake City 2002 Olympic Winter Games. After two seasons of results below her very high standards in 2004 she decided to move to Ruhpolding, where she recaptured her formfinishing second only to the Frenchwoman Sandrine Bailly in the BMW IBU World Cup Overall Rankings for 2004/2005 season. At the Torino 2006 Olympic Winter Games she was the proud carrier of the German flag at the opening ceremony. Olympic Torino - after Cortina d’Ampezzo hosting second Olympic Winter Games in history in Italy - with gold medal in 10 km pursuit and silver medals in mass start and relay competitions proved to be the final trigger for Wilhelm’s most successful season for not only she became the most decorated biathlete at the Olympic Winter Games ever at that stage, she also continued to dominate the BMW IBU World Cup competitions, winning six races and capturing her first BMW IBU World Cup Overall title. No wonder she was elected "Biathlete of the year 2006" as well as "German sportswoman of the year 2006". In the 2006/2007 BMW IB World Cup season, she finished second in the Overall Rankings World Cup behind teammate Andrea Henkel. In the 2008-09 World Cup season, she finished second in the dramatic battle for theBMW IBU World Cup Overall scoring 952 world cup points just like Helena Jonsson of Sweden, with Jonsson being awarded the overall title by virtue of her four BMW IBU World Cup wins against Wilhelm’s three. The German media gave her the nickname "Rotkäppkchen" (Little Red Riding Hood) because of her characteristic red hair and the red cap she used in competition. She was able to translate her Olympic victories into multiple endorsement deals. Wilhelm announced her retirement from biathlon on 9 March 2010 so that she could focus on her studies.
