Usain Bolt, in total Usain St. Leo Bolt, (born August 21, 1986, Montego Bay, Jamaica), a Jamaican sprinter who won gold awards in the 100-metre and 200-metre races within an unprecedented three consecutive Olympic Games and is widely regarded as the greatest sprinter of all time.
Bolt, the son of grocers at Jamaica's rural Trelawny parish, excelled as a cricket fast bowler in his preteen years. He also developed a deep affection for its European football (football ) teams Real Madrid and Manchester United, but his college coaches steered his to track and field.
Bolt first declared himself as a monitor prodigy in the 2002 world junior championships. In that meet, racing before a crowd of 36,000 at Jamaica's National Stadium in Kingston, Bolt--only 15 years old at the time--won gold in the 200 metres, becoming the youngest-ever male world junior champion in any event.
At age 16 Bolt cut on the junior (age 19 and under) 200-metre world album to 20.13 sec, and at 17 he conducted the event in 19.93 sec, getting the first teenager to break 20 seconds in the race. However, hampered by a hamstring injury, he failed to advance past the 200-metre heats at the 2004 Olympics in Athens and put last in the 2005 world track-and-field championships final.
At 6 feet 5 inches (1.96 metres), Bolt defied the conventional wisdom that very tall sprinters are disadvantaged as fast starters. In 2007 he seemed recently devoted to his coaching and got a silver medal in the 200 metres at the world championships.
In addition, he persuaded his trainer to let him try the 100 metres, and he conducted 10.03 sec in his first professional race in the distance. On May 3, 2008, he reduced his best time to 9.76 sec, then the world's second-fastest mark.
