Usain St. Leo Bolt, OJ, C.D. (pronounced /ju?'se?n/; born 21
August 1986), is a Jamaican sprinter and a three-time Olympic gold
medalist. He holds the world record for the 100 metres, the 200
metres and, along with his teammates, the 4x100 metres relay. He
also holds the Olympic record for all three of these races. At the
2008 Summer Olympics, Bolt became the first man to win three
sprinting events at a single Olympics since Carl Lewis in 1984, and
the first man to set world records in all three at a single
Olympics. In 2009 he became the first man to hold the 100 and 200 m
world and Olympic titles at the same time.
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, he
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. He turned professional in 2004,
missing most of his first two seasons due to injuries, but he
competed at the 2004 Summer Olympics. In 2007, he 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. He set world records in both 100 m and 200 m events at the 2008
Beijing Summer Olympics: 100 m record time of 9.69 s broke his own
previous record of 9.72 s; with a record time of 19.30 s he broke
previous record of 19.32 s by Michael Johnson at the 1996 Summer
Olympics in Atlanta. In August 2009, a year after the Beijing
Olympics, he lowered his own 100 m and 200 m world records to 9.58
s and 19.19 s respectively at the 2009 World Championships. His
record breaking margin in 100 m is the highest since the start of
digital time measurements.
His achievements in sprinting have earned him the media nickname
"Lightning Bolt".
