Bolt’s appeal has transcended sport, due to his charismatic and laid-back approach. In a sport riddled with allegations of drug use, Bolt has retained a clear record. A retrospective ban on a teammate resulted in Sprinter Usain Bolt losing one relay gold.
Early life of Sprinter Usain Bolt
Usain was born on 21 August 1986 in Sherwood Content, a small town in Trelawny, Jamaica. As a youngster he was mostly interested in sports, spending time playing football, cricket and basketball. At one time he considered a career as a cricketer but, his natural talent for sprinting shone through, and so he was encouraged to take sprinting more seriously. At 15 years old, Usain already towered over his fellow competitors. Growing to a height of 6 foot 5 inches, Bolt showed a sprinter need not be short and powerful like previous sprinting greats.
In 2002, he won Gold at the World Junior Championships in the 200 metres. At this stage in his career, Usain seemed to convey a laid-back impression. He didn’t lead an austere disciplined life but enjoyed dancing and the night-life of Kingston, Jamaica. However, he was still training hard and won Gold at the World Youth Championship in the next year at 2003.
In 2004, Bolt turned professional, under the guidance of new coach Fitz Coleman. He began his career with the CARIFTA Games in Bermuda. He became the first junior sprinter to break 20 seconds for the 200 metres. By 2005, Usain had a new coach Glen Mills .He encouraged Usain to take a more professional approach and not just rely on his natural talent. Over the next few years, injury setbacks curtailed his career, but, he was still able to climb the rankings.
His big breakthrough came in the 2007 World Championships where he gained silver in the 200m and 4*100 metre relay. Bolt established a new 100m world record on 31 May 2008. Pushed on by a tailwind of 1.7 m/s, Bolt ran 9.72 s at the Reebok Grand Prix held at the Icahn Stadium in New York City, breaking Powell’s record.
2008 Olympics Sprinter Usain Bolt
Usain Bolt went into his first Olympic Games as one of the favourites, despite his youth and inexperience at major championships. 
Some quarters criticized him for celebrating before the finish line. But Bolt’s dominance and speed remained unquestioned.His time of 9.69s was a world record, and if he had kept going to the end, he could have perhaps gone under 9.60 In the 200 metres, Bolt again won gold and even more surprisingly broke Michael Johnson’s long-standing world record.
By the next World Championships in Berlin 2009, Bolt was able to again dominate all the sprint events. He won a clean sweep at the 100m, 200m and 100m relay. Again he set remarkable World Record times, lowering the time for 100 metres to 9.58 and 19.19 for 200 metres. On the last day of the Berlin Championships, the Governing Mayor of Berlin, Klaus Wowereit, presented Bolt with a 12-foot high section of the Berlin Wall in a small ceremony. He said Bolt had shown that “one can tear down walls that had been considered as insurmountable.”
2012 Olympics
Despite being beaten by his training partner, Yohan Blake, during pre-Olympic events at the Jamaican national championships, Bolt won three gold medals.Bolt won the 100m and 200m . He was part of the team that set a new world record in the men’s 100m relay.
2013 World Championships

Sprinter Usain Bolt in 2014
Injuries marred Bolt’s 2014 season, leading to a reduction in his racing program. Bolt has stated that his body has become more prone to injury as his athletic career progresses. In the Glasgow 2014 Commonwealth Games, Bolt chose not to run in the individual 100m, but he did compete in the 100m relay. Bolt anchored the team to a gold medal and proved to be the star attraction of the games.
2016 Olympics
Bolt’s run up to the 2016 Olympics was not ideal with frequent injury problems curtailing his racing and training.He determinedly chose to finish with a flurry, announcing his retirement shortly after the 2016 Games.
Bolt was the undoubted superstar of the Games. Despite poor attendances in Rio, Bolt always managed to attract a full crowd. Bolt again managed to win gold in all three events – the 100m, 200m and 100m relay. It was a perfect bag of nine Olympic golds – a feat never before achieved. Sprinter Usain Bolt has announced that he will retire from athletics after the 2016 Olympics.
Sprinter Usain Bolt and drugs
Usain Bolt has shown tremendous talent ever since he first started running. His timings are consistent with an athlete of tremendous talent. As Bolt himself says:
“I was the youngest person to win the world juniors at 15. I ran the world junior [200] record 19.93 at [17] … I have broken every record there is to break, in every event I have ever done. “For me, I have proven myself since I was 15. … I have shown everything throughout the years since I was always going to be great.”
The IAAF international testing pool regularly tests Usain Bolt. He has never tested positive for any banned substances.Given the sport’s history, questions have inevitably arisen regarding the issue of drug use.The biggest cause for concern has been from the perceived inadequacies of the Jamaican Athletic Federation. In 2013, it emerged that they had failed to undertake proper out of competition testing in the run-up to the 2012 London Olympics. This failure to implement proper drug testing was compounded by six Jamaican athletes. It included the former world 100m record holder Asafa Powell and Veronica Campbell-Brown, testing positive for banned substances. WADA announced an extraordinary audit of the Jamaican testing programme. They have even threatened to ban Jamaican athletes from international competition.

“I was made to inspire people and to run, and I was given the gift and that’s what I do,” the six-time Olympic champion said. “I am confident in myself and my team, the people I work with. And I know I am clean. “So I’m just going to continue running, using my talent and just trying to improve the sport.”
In Jan 2017, it was announced that Bolt’s teammate, Nesta Carter, from the 2008 Beijing Olympics had retroactively tested positive for a stimulant methylhexaneamine, and therefore the whole team were stripped of their gold medal.
Bolt retired after the 2017 World Championships in London. In his last major 100m final, Bolt finished in 3rd place. It was slightly off his usual blistering pace, after an injury-hit year. In his last ever race, he was anchor leg in the 4x100m final. After receiving the baton he pulled up with an apparent hamstring injury and hobbled over the line.
Since his retirement, Usain Bolt has actively participated in establishing Jamaican food outlets in the UK. So far, he has insisted he has no plans to return to the track.
