Bjerre began his Polish league career in 2001 for
Ostrów. Over the following decade he would become a heat leader for both
Belle Vue Aces (2004 to 2006) and
Peterborough Panthers (2007 to 2010). In September 2008, during the
Speedway Grand Prix Qualification he won the
GP Challenge, which ensured that he claimed a permanent slot for the
2009 Grand Prix. During the 2009 Grand Prix series he finished in 8th place, which meant that he retained a permanent rider for the
2010 Grand Prix. His consistency resulted in a 7th place finish in both the
2010 Speedway Grand Prix and
2011 Speedway Grand Prix but he dropped out of the Grand Prix after a disappointing 2012 campaign. He raced in the United Kingdom for
Peterborough Panthers and
King's Lynn Stars in the
Elite League. In 2017, he raced for the Belle Vue and averaged 8.95. The following year he appeared for
Leicester Lions before going back to Belle Vue for the 2019 season, in which he became the champion of Denmark after winning the 2019
Danish Individual Speedway Championship. ==Personal life==
