11. Charles Hefferon and Dorando Pietri: 1908 marathon. Hefferon led until the last few kilometers, when he accepted an ill-advised glass of victory champagne from a spectator ... and became ill. He was overtaken by Pietri, who entered the stadium exhausted and dehydrated ... and became ill. Pietri took the wrong path, collapsed, was redirected, and collapsed four more times. Helped to his feet, Pietri won but was later DQ'd for accepting asistance.
