Usain Bolt is a Jamaican sprinter who holds the world record for the 100, 200, and 4x100 meter relay race. In the olympics, he ran a 9.69 in the 100 meters (which some people said could have been lower if he didn't jog the last 30 meters), a 19.30 in the 200, and in the 4x100 meter relay, the Jamaican team ran a 37.10 which was the 3rd of Bolt's medals. He started to run as a little kid, and in the 2002 Junior Championships, he won gold. The following year he turned pro, but did not have much success. He had multiple injuries and sat out for most of the season. In the 2004 olympics, he lost in the first round, but rebounded in 2007 when he set Jamaica's record in the 200 meters with a 19.75. In May of 2008, he set the world record at a meet in New York when he ran a 9.72 in the 100 meter dash. At first, his coach was not going to allow Bolt to run it, but after some persuading, he gave in. Then, at the 2008 olympics, Bolt set world records in all events he was in and people began calling him "Lightning" Bolt.
