9. Kurt Jenson and others
When the Danish rider, Kurt Jansen collapsed during the 1960 Rome Olympics, from an amphetamine overdose, drugs in cycling became big news.
Like many sports, it attempted to play down the situation. In 2003, after years of ignoring the problem, it had no choice but to face up to it.
During a period of just 13 months 8 elite cyclist, 4 under 24 years old, and one of them only 16, died of a heart attack. Commentators stated the drug EPO as the reason.
With Michael Rasmussen and Alexandre Virokourov both disqualified at this years Tour de France, critics claim the sport is still rife with drugs, but as Lance Armstrong pointed out at least it shows the cycling world are finally trying resolve the problem.
