Johan Sermon, a Belgian cyclist with the Daikin team, died on Feb. 13 from an apparent heart attack. He was 21.
In preparation for an eight-hour training ride, Sermon had gone to bed early on Thursday night. His mother found his body the next morning. Ernest De Vuyst, team manager and the former president of the Belgian Cycling Federation, said Sermon had recently undergone a complete cardiovascular check-up.
Since January 2003, eight riders have died from heart attacks.
