Sven Nys (; born 17 June 1976) is a former professional cyclist competing in cyclo-cross and mountain bike. With two world championships, seven world cups, and over 140 competitive victories, he is considered one of the best cyclo-cross racers of his generation, and remains a prominent figure in cyclo-cross. Apart from cyclo-cross, Nys is also fivefold national mountainbike champion, and has competed in that discipline in two Olympic games. Career overview Early years Born in Bonheiden, Belgium, Nys began racing BMX at the age of 8. He won eight BMX national titles before switching to cyclocross, a more popular sport in Belgium. He won the under-23 world championship in 1997 and 1998, beating another Belgian, Bart Wellens. Nys moved to the elite category in 1998–1999, joining the Dutch team. Becoming elite In the elite class he won the Superprestige competition and came third in the national championships. The next season, he won the Superprestige again, ended the World Cup as leader and became Belgian champion. This made him favourite for the 2000 world championship. But his Rabobank management told him not to beat his teammate, the Dutchman Richard Groenendaal. Groenendaal sprinted away from the start and Nys was forced to hold back and not help another Belgian, Mario De Clercq, chase him. Groenendaal won and Nys, who came third, was criticised in Belgium for choosing team over country. The Royal Belgian Cycling League demanded an explanation. It became more forgiving but the head coach, Erik De Vlaeminck, remained unconvinced. Nys blamed an injury for not winning a season-long competition or championship in 2000–2001. A year later he won the World Cup and the Superprestige again. In the world championships that year he came third after being outsprinted by De Clercq and Tom Vannoppen. The following season Nys won the Superprestige for the fourth time as well as the Gazet van Antwerpen trophy for a first time. He became Belgian champion again, but Wellens won the world championship and the World Cup. Wellens dominated 2003–2004. Nys' chance for the World Cup ended when other Belgians sprinted past him, taking points. Nys was angry that his countrymen had allowed Groenendaal, a Dutchman, to win the World Cup rather than him. That evening Nys decided from then on to ride for himself. The cannibal Nys won everything of importance and at the end of 2004–2005 won the national and world championships, ended number
