Ole Einar Bjørndalen is a retired Norwegian professional biathlete and coach, often referred to by the nickname, the "King of Biathlon". With 13 Winter Olympic Games medals, he is second on the list of multiple medalists behind Marit Bjørgen who has won 15 medals. He is also the most successful biathlete of all time at the Biathlon World Championships, having won 45 medals. With 95 World Cup wins, Bjørndalen is ranked first all-time for career victories on the Biathlon World Cup tour. He has won the Overall World Cup title six times, in 1997–98, in 2002–03, in 2004–05, in 2005–06, in 2007–08 and in 2008–09.

The first Biathlon World Championships (BWCH) was held in 1958, with individual and team contests for men. The original team event, Team (time), was held for the last time in 1965, to be replaced in 1966 by the team event, Relay, which we know today. The number of events has grown significantly over the years. Beginning in 1984, women biathletes had their own World Championships, and finally, from 1989, both genders have been participating in joint Biathlon World Championships. In 1978 the development was enhanced by the change from the large army rifle calibre to a small bore rifle, while the range to the target was reduced from 150 to 50 meters.
