Sep 15, 2000

With a return to Australia, 10,600-plus athletes from 199 teams compete in the 2000 Games. North and South Korea march under one flag and it’s the first time EPO detection and blood tests are used. American track star Marion Jones wins five medals in 2000, but loses them in 2007 after admitting to using performance-enhancing drugs. Newly added sports include taekwondo and the triathlon and women compete in weightlifting and the modern pentathlon for the first time. Perhaps the breakout star of the Olympics is a teenager: At age 17, Australian swimmer Ian Thorpe breaks his own world record to win the 400-meter freestyle. He also takes gold in two relays and wins two silvers.
