Cause of death: cancer
Laurent Patrick Fignon (French pronunciation: [loʁɑ̃ fiɲɔ̃]; 12 August 1960 – 31 August 2010) was a French professional road bicycle racer who won the Tour de France in 1983 and 1984, as well as the Giro d'Italia in 1989. He held the title of FICP World No. 1 in 1989. Fignon came close to winning the Tour de France for a third time in 1989 but was narrowly defeated by Greg LeMond by 8 seconds, marking the closest margin ever to decide the Tour. Fignon won many classic races, including consecutive victories in Milan–San Remo in 1988 and 1989. He died from cancer in 2010.
