          Usain St Leo Bolt 

                      Bolt was born on 21 August 1986 in Sherwood Content.He is the first person to hold both 100 metres and 200 metres world records since fully automatic time became mandatory. He also holds the world record as a part of the 4 × 100 metres relay. He is the reigning Olympic champion in these three events. Because of his dominance and achievements in sprint competition, he is widely considered to be the greatest sprinter of all time.a small town in Jamaica, the son of Wellesley and Jennifer Bolt. He has a brother named Sadiki and a sister named Sherine. His parents ran the local grocery store in the rural area, and Bolt spent his time playing cricket and football in the street with his brother, later saying, "When I was young, I didn't really think about anything other than sports." As a child, Bolt attended Waldensia Primary, where he first began to show his sprinting potential, running in the annual national primary-schools' meeting for his parish. By the age of twelve, Bolt had become the school's fastest runner over the 100  metres distance.
                                                                             
                    Upon his entry to William Knibb Memorial High School, Bolt continued to focus on other sports, but his cricket coach noticed Bolt's speed on the pitch and urged him to try track and field events. Pablo McNeil, a former Olympic sprint athlete, and Dwayne Jarrett coached Bolt,encouraging him to focus his energy on improving his athletic abilities. The school had a history of success in athletics with past students, including sprinter Michael Green. Bolt won his first annual high  school  championships medal in 2001, taking the silver medal in the 200  metres with a time of 22.04 seconds. McNeil soon became his primary coach, and the two enjoyed a positive partnership, although McNeil was occasionally frustrated by Bolt's lack of dedication to his training and his penchant for practical jokes. 
        
          Bolt improved upon his first 100 m world record of 9.69 with 9.58 seconds in 2009 – the biggest improvement since the start of electronic timing. He has twice broken the 200 metres world record, setting 19.30 in 2008 and 19.19 in 2009. He has helped Jamaica to three 4 × 100 metres relay world records, with the current record being 36.84 seconds set in 2012. Bolt's most successful event is the 200 m, with three Olympic and four World titles. The 2008 Olympics was his international debut over 100 m; he had earlier won numerous 200 m medals (including 2007 World Championship silver) and holds the world under-20 and world under-18 records for the event.
His achievements as a sprinter have earned him the media nickname "Lightning Bolt", and his awards include the IAAF World Athlete of the Year, Track & Field Athlete of the Year, and Laureus World Sportsman of the Year(four times). Bolt has stated that he intends to retire from athletics after the 2017 World Championships.
