Bolt backs up his Beijing performance
Once again, Usain Bolt stole the Olympic show. He easily won the 100-meter dash in an Olympic-record time, then captured the 200-meter dash four days later. And then came the capper, a world-record time for Jamaica in the 4x100-meter relay, with Bolt running the final leg and ensuring that the United States could do no better than second on that night. Gold, gold, gold in London. Gold, gold, gold in Beijing. And he became the first man to win the 100-200 double at consecutive Olympics.
