Klaus Nielsen
Klaus Nielsen is a Danish professional mountain biker. He has won four Danish national championship titles in both men's cross-country and marathon races, and also represented his nation Denmark, as a 28-year-old senior, at the 2008 Summer Olympics. Nielsen currently trains and races professionally for Germany's Team ALB-Gold Mountain Bike Team.
Nielsen qualified for the Danish squad, along with his teammate Jakob Fuglsang, in the men's cross-country race at the 2008 Summer Olympics in Beijing by receiving one of the nation's two available berths for his team from the Union Cycliste Internationale, based on his top-ten performance at the World Cup series and Mountain Biking World Series. With one lap to go, Nielsen struggled to keep his form throughout a 4.8-km sturdy, treacherous cross-country course, and instead pulled off directly from the race by taking the thirty-first spot.
