Usain Bolt sprint training and 100 meter world record video

DOB: born 21 August 1986
Usain Bolt CD is a Jamaican sprinter. Bolt holds the Olympic and world records for the 100 metres at 9.69 seconds, the 200 metres at 19.30 seconds and, along with his teammates, the 4×100 metres relay at 37.10 seconds, all set at the 2008 Summer Olympics. Bolt became the first man to win all three events at a single Olympics since Carl Lewis in 1984, and the first man in history to set world records in all three at a single Olympics. His name and achievements in sprinting have earned him the media nickname “‘Lightning’ Bolt”.

Bolt distinguished himself with a 200 m gold medal at the 2002 World Junior Championships, making him the competition’s youngest-ever gold medalist. In 2004, at the CARIFTA Games, Bolt became the first junior sprinter to run the 200 m in under 20 seconds with a time of 19.93 s, breaking Roy Martin’s world junior record by two-tenths of a second. Bolt also set competition records at a number of other junior events.

Bolt turned professional in 2004 but missed most of his first two seasons due to injuries; he was eliminated in the first round of the 200 m heats at the 2004 Summer Olympics. In 2007, Bolt beat Don Quarrie’s 200 m Jamaican national record with a run of 19.75 s. In May 2008, Bolt set his first 100 m world record with a time of 9.72 s, improving upon his previous personal best of 9.76 s which was made earlier in the month.

As a result of Bolt’s successes in athletics, he was named the Laureus World Sportsman of the Year for 2009.
