Doping at the Summer Olympics
Olympic athletes have tried to boost their performances since at least 1904, when the marathon winner drank brandy and strychnine during the race. Some won, some got sick, and one Danish cyclist died. But none of it was against the rules until the late 1960s, when the International Olympic Committee banned doping and began to test for it. Since then, cheaters often have been a few steps ahead of those who try to catch them.
