Usain Bolt, that freakishly fast Jamaican guy, ran the fourth fastest 200-meter race in human history at the World Athletic Championships in Daegu, South Korea today. He clocked 19.40 seconds. Only two people have ever run faster. One is named Michael Johnson. The other is named Usain Bolt.

The fact he was in lane three meant that he was cramped for room. "It put a lot of strain on my body," and meant he could not accelerate smoothly out of the bend into the straight. "It was so tight," he said, "that I had to be conservative and run a more technical race."
