Who: Aleksandr Karelin
Olympics: Sydney 2000

Russian Greco-Roman superheavyweight Aleksandr Karelin entered the 2000 Games on what some would call a hot streak. He had never lost in 13 years, won three consecutive Olympic gold medals and had not even given up a point in the past ten years. In the gold medal match, however, Karelin's streak came to an end at the hands of American Rulon Gardner. Gardner, who had never won a major wrestling title, upset the heavily favored Karelin who tired as the match went on. Fatigue played a large role in the match as it was Karelin's third match of the day compared to Gardner's second.
