Vojens has a rich history in motorcycle speedway and hosted the World Final on two occasions (1988 and 1994) at the Vojens Speedway Center. The Speedway Center is part-owned by Denmark's first triple World Champion Ole Olsen, and has also hosted the Speedway Grand Prix of Denmark as part of the Speedway Grand Prix from 1995-2002 after which the SGP series moved the Danish GP to the Parken Stadium in Copenhagen.
The Vojens Speedway Center also hosted the Speedway World Team Cup final in 1983, 1986 (as Round 2 of a 3 Round Final), 1991 and 1998. The World Team Cup was replaced with the Speedway World Cup following 2000 and the Speedway Center hosted the 2003, 2008 and 2010 finals. Also held were the 1979 Speedway World Pairs Championship and the 1977 Under-21 European Championship. The Under-21 championship became the World Under-21 Championship in 1988 and Vojens hosted the 1999 Under-21 World Final.
