Usain St. Leo Bolt is a Jamaican sprinter who is infamous as the fastest person ever. He is the reigning Olympic champion in these three events, the first man to win six Olympic gold medals in sprinting, and a five-time World champion. He was the first to achieve a "double double" by winning 100 m and 200 m titles at consecutive Olympics (2008 and 2012). His 2009 record breaking margin for 100 m, from 9.69 seconds (his own previous world record) to 9.58, is the highest since the start of fully automatic time measurements. He is the first man to hold both the 100 metres and 200 metres world records since fully automatic time measurements became mandatory in 1977. Along with his teammates, he also set the world record in the 4Ã100 metres relay. Performing for Jamaica in his first Caribbean regional event, Bolt clocked a personal best of 48.28 s in the 400 metres in the 2001 CARIFTA Games, winning a silver medal. He made his first appearance on the world stage at the 2001 IAAF World Youth Championships in Debrecen, Hungary. As a member of the Jamaican sprint relay team, he also took two silver medals and set national junior records in the 4Ã100 metres and 4Ã400 metres relay, running times of 39.15 s and 3:04.06 minutes respectively. Under the guidance of new coach Fitz Coleman, Bolt turned professional in 2004, beginning with the CARIFTA Games in Bermuda. For the second time in the role, he was awarded the Austin Sealy Trophy for the most outstanding athlete of the 2004 CARIFTA Game. His accolades and achievements in athletics have earned him nickname "Lightning Bolt". He is also recipient of many awards including including the IAAF World Athlete of the Year, Track & Field Athlete of the Year, and Laureus Sportsman of the Year (twice).
