Alex Zülle (born July 5, 1968 in Wil, Switzerland) is a Swiss road bicycle racer. During the 1990s he was one of the best cyclists in the world, winning Vuelta a España two times and taking the second place in 1999 Tour de France.
During his career, Alex Zülle raced for the following teams: ONCE (1991-1997), Festina (1998), Banesto (1999-2000), Coast (2003), Phonak (2003-2004). Although Zülle has an impressive palmarès, his career unfortunately coincided with the one of Miguel Indurain, five times Tour de France winner and of Lance Armstrong, the seven times Tour de France winner, which meant that he never won the Tour de France, but finished this prestigious race twice as second best. Furthermore, Zülle met with success in the Vuelta, Giro d'Italia, Tour de Suisse, Tour de Romandie and other races. Zülle retired in 2004.
In 1998 Zülle was part of the Festina team which got banned from the 1998 Tour de France because of serious doping allegations. This known as the Festina Scandal. See Doping at the Tour de France.
