Usain Bolt wants everyone to know that he's the greatest. He has become the only man to repeat gold in both the 100m and now the 200m as well. For this era, at least, he is unbeatable. His teammate, Yohan Blake, gave him a run for his money, though. With Bolt's unbelievable stride length, Blake came up just short at the finish line. As expected, he finished with the silver in a comfortable lead over the next finisher.
