Oscar Camenzind

Oscar Camenzind is a former professional road racing cyclist from Switzerland. He became national road champion in 1997. In 1998 he won the World Road Championship and the Giro di Lombardia, in 2000 the Tour de Suisse and Liège–Bastogne–Liège in 2001. His career came to an abrupt end when he retired from pro cycling after a positive doping test in July 2004 for erythropoietin, leading into the Athens Olympics. After confessing to the use, in 2005 he was sued in Swiss court in order to name his supplier, which he refused to do fearing retribution.
