Asafa Powell (born 23 November 1982) is a Jamaican retired sprinter who specialised in the 100 metres. He set the 100 metres world record twice, between June 2005 and May 2008 with times of 9.77 and 9.74 seconds. Powell has consistently broken the 10-second barrier in competition, with his personal best of 9.72 s ranking fourth on the all-time list of men's 100-metre athletes. As of 1 September 2016, Powell has broken the 10-second barrier more times than anyone else—97 times. He currently holds the world record for the 100-yard dash with a time of 9.07 s, set on 27 May 2010 in Ostrava, Czech Republic. In 2016, he became Olympic champion in the 4 × 100 metres relay.

Powell competed in the 100 m at the 2004, 2008 and 2012 Olympics, finishing fifth in 2004 and 2008 and eighth after injuring his groin during the race in 2012. At the 2007 Osaka World Championships, he achieved a bronze and a silver medal in the 100 m and 4 × 100 m relay respectively, and he was successful at the Commonwealth Games, winning twice plus achieving a silver medal. At the 2009 World Championships, he achieved the 100 m bronze and became champion in the relay. Powell has won five times at the IAAF World Athletics Final and was the former 100 m world record holder in the event.

In 2013, Powell tested positive for the stimulant oxilofrine along with teammate Sherone Simpson and voluntarily withdrew from the 2013 World Athletics Championships as a result, though both maintained they did not take any banned supplements knowingly or willfully. On 10 April 2014, they received an 18-month suspension from competing, which was set to expire in December that year. However the Court of Arbitration for Sport (CAS) lifted both athletes' suspensions on 14 July 2014, finding that the positive tests were caused by the presence of oxilofrine, undisclosed by the manufacturer, in a supplement taken by the pair.

Powell won a lawsuit against the Supplement company for failing to disclose the banned stimulant.

Biography and sprinting career

Born in Spanish Town, Jamaica, Asafa Powell is the youngest of six sons of two ministers. Asafa attended Ewarton Primary School and Charlemont High School, both in St. Catherine, Jamaica. Powell planned to be a mechanic before he took up running while studying in Kingston, Jamaica. His eldest brother Donovan, was a 60 m finalist in the 1999 World Indoor Championships. Running runs in the family: His brothers clocked 9.5 seconds for the 100 yd dash, his mother 11.4 s, and his father 10.2 s. and has been coached by Stephen Francis since 2001.

2000–2005: Early career

Powell represented his school Charlemont High at the ISSA High School Championships. On 11 April he finished fourth in the Class 1 200 m, in 23.07 with a −1.7 m/s headwind. On 13 April, he finished third in his heat of the Boy's Class 1 100 m, recording 11.45 with a −2.3 m/s headwind. Neither time recorded in the heats was quick enough to advance him to the next round of competition.

Powell again represented Charlemont High at the ISSA High School Boy And Girls Championships, finishing seventh in the Class 1 100 m Final. Recognizing some talent, coach Stephen Francis started coaching Powell one week later. The coach looked for a way to give the tall teenager a faster start. After searching the island, Stephen Francis found a 100 m stretch of road with a 10% slope and trains his runners on that. Powell vindicated Francis by winning the Boys Under-20 100 m event in 10.50 seconds at the JAAA National Championships on 22 June.

At the 2002 Commonwealth Games in Manchester, Powell finished fifth in the semi-finals of the 100 m event, setting a personal best of 10.26 s. Powell, along with Michael Frater, Dwight Thomas and Christopher Williams formed the Jamaican 4 × 100 m relay team that went on to win a silver medal. Powell finished just behind Darren Campbell in the last leg of the relay, with both men finishing in 38.62 s.

Powell won the Jamaican 100 m National Championship in 2003.

Powell came to attention within the world of athletics at the 2003 World Championships, when he suffered the ignominy of being 'the other athlete' disqualified for a false start in the quarter-final. This was when Jon Drummond memorably refused to leave the track having suffered the same fate, both athletes moved less than 0.1 s after the gun had fired, with Powell's reactions being timed at 0.086 s. Six days later Powell was added to the 4 × 100 m relay team for the semi-final, running as the anchor. He helped the team qualify for the final, recording the second fastest time. Powell never had a chance to run for a medal in the final as the second baton exchange was not executed cleanly and the Jamaican team failed to finish. During the 2003 season, Powell won two IAAF Grand Prix events, one of which was an AF Golden League event. He finished seventh in 10.23 s in the 100 m at the IAAF World Athletics Final.

In 2004 on 12 June, Powell recorded his first sub-10 100 m race time (9.99 s +1.8 m/s) while participating in the National Junior Track and Field Championships, held at the GC Foster College in Spanish Town. Two weeks later Powell became one of the favourites for a medal in the 100 m at the 2004 Athens Olympics after winning the Jamaican National Championships with a personal best time of 9.91 s. Although he ended the season with a record-equaling nine sub-10 second runs, Powell finished just fifth in the highly competitive Olympic final, with a time of 9.94 s. Following this he pulled out of the 200 m final, even though he had already qualified eighth for it earlier on. Powell did not get the chance to run for a medal in the 4 × 100 m relay, as the Jamaican team failed to qualify for the final with a season best 38.71 s fourth-place finish in their heat. Following his Olympic disappointment Powell set a new national record of 9.87 s for the 100 m at the Memorial Van Damme in Bruxelles on 3 September. He recorded five IAAF Grand Prix wins in 2004. In addition, he became the first man to win both the 100 m and 200 m races at the World Athletics Final in championship record time. Powell was world ranked number one for the 100 m and number four for the 200 m at the end of the season.

A year later Powell set a new national record of 9.84 s at the Jamaica International Invitational in May. He gained some consolation for his Olympic performance by breaking the 100 m world record in Athens on 14 June 2005, setting a time of 9.77 s, beating American Tim Montgomery's 2002 record of 9.78 s (which was later annulled due to doping charges against Montgomery) by just 0.01 s. Coincidentally, Powell achieved the feat on the same track as Maurice Greene's 1999 world record run of 9.79 s. Wind assistance for Powell was measured at 1.6 m/s, within the IAAF legal limit of 2.0 m/s. Powell again won the 100 m final at the Jamaican National Championships. A groin injury in July cut short his season and forced him to miss the World Championships. His season ended with just two IAAF Grand Prix event wins. Despite his shortened season, Powell had the three fastest 100 m times of the year, received the Caribbean And Central American (CAC) Male Athlete of the Year award, and ranked second in the world. In addition to winning the 200 m at the Jamaican National Championships in June, he won ten 100 m IAAF Grand Prix events, including all six Golden League events.

Powell then equalled his world record time on 11 June 2006 at Gateshead International Stadium with wind assistance measured at +1.5 m/s. The exact time was 9.7629 s, which was rounded up to 9.77 s as per IAAF rules. On 18 August 2006 in Zürich, Powell equalled it again for the second time with wind assistance at +1.0 m/s. He won his sixth IAAF Golden League event (for the 100 m) in the same season, thus earning him a total of $250,000 in prize money. Powell also won the 100 m at the World Athletics Final, again setting a new championship record on 9 September. One week later at the World Cup in Athletics, the Americas team anchored by Powell recorded a DNF. In October, Powell again received the Caribbean And Central American (CAC) Male Athlete of the Year award. On 12 November 2006, he was awarded the title of 2006 Male IAAF World Athlete of the Year along with a cheque for $100,000. He also received the honour of Track & Field Athlete of the Year for 2006.

On 5 January 2007, Powell received the Commonwealth Games Sports Foundation Athlete of the Year award. On 3 February he was honoured at the International Sports Group (ISG) Awards Banquet, held in New York. In addition, Powell was nominated for the Laureus World Sports Awards Sportsman of the Year award. Suffering from knee Tendinitis and missing weeks of training Powell missed competing at the Penn Relays and the Jamaica International Invitational in May. Powell was again the Jamaican National Champion for the 100 m. Unfortunately, Powell again injured his groin while running the final at the Jamaica Championships. He only managed to finish third in the 100 m final at the 2007 World Championships in Osaka, Japan, behind Tyson Gay, who was considered Powell's biggest rival building up to the Championships. Derrick Atkins, Powell's second cousin, came second in 9.91 s. Powell himself finished in a time of 9.96 s (running in a 0.5 m/s headwind) after being passed by Gay and Derrick Atkins in the late stages of the race. Later, Powell admitted that he panicked and gave up after seeing Gay pass him, allowing Atkins also to overtake.

American former sprinter Michael Johnson was critical of Powell's performance, stating:

However, Powell did help to win the silver medal in the 4 × 100 m relay race. Running the anchor leg for the Jamaican team, he came from fifth and passed Great Britain at the line to help record a Jamaican national record of 37.89 s. The United States meanwhile took gold.

On 9 September 2007, in the opening heats of the IAAF Grand Prix in Rieti, Italy, Powell ran a new world record time of 9.74 s (+1.7 m/s) in the 100 m, thus fulfilling the promise he had made earlier after his bronze medal in Osaka, that he would break the record by the end of the year. This was intended to make up for the disappointment of not becoming World Champion. Remarkably, Powell eased up in the final few metres of his record-setting run, indicating that he was saving his strength for the final. In the final itself, Powell finished in 9.78 s (0 m/s windspeed) and bettered his semi-final time when adjusted for wind assistance.

Powell ended his season on 30 September with a left hamstring injury, which came about while running in the lead of the 200 m race at the Super Track & Field meet in Yokohama, Japan. Powell finished 2007 with a total of five IAAF Grand Prix event wins, plus his second consecutive World Athletic Final 100 m win, with yet another championship record. For the third consecutive year Powell won the Caribbean And Central American (CAC) Male Athlete of the Year award. Powell closed the year receiving the IAAF Performance of the Year award, for his 9.74 s world record, and was ranked second in the world. Powell's 2008 season started much as his 2007 season ended: with another injury. Powell was forced to pull out of the Sydney Grand Prix meeting, having suffered a gash to his left knee that required four stitches. The injury was a result of tripping on the steps of his home, hours before getting on the flight to Sydney on 12 February.

Powell was again injured in April, this time with damage to his pectoral muscles. The injury forced Powell out of competition for two months, and was sustained while weight training in Jamaica during mid-April. Surgery was required, and a visible scar was left on his right underarm.

On 31 May, fellow Jamaican Usain Bolt ran a time of 9.72 s at the Reebok Grand Prix in New York, breaking Powell's 3-year dominance of the 100 m world record.

On 11 July, Powell suffered his third injury of 2008 while leading in Heat 1 of the Golden Gala Roma, eventually finishing fifth. He had injured his groin (described as a "strain" and a "cramp"), and was forced to miss the next two events on the Grand Prix schedule. Powell made his comeback at the DN Galan meet, where he beat the new World Record holder Bolt, in a close race. The meet's top performers were a Jamaican 1–2–3–4 with Nesta Carter and Michael Frater following the pair. This top four would later combine to run the 4 × 100 m relay at the Olympics.

Prior to the 2008 Olympics in Beijing, Powell hit back at the claims saying he lacked the mental strength needed to win an Olympic gold medal.

Despite his words, the 100 m final saw Powell again finish in a disappointing fifth, recording a time of 9.95 s. Teammates Bolt and Michael Frater also raced in the final. Bolt won and broke the record he set months earlier (finishing in 9.69 s) and Frater came sixth, recording his first sub-10 clocking at 9.97 s.

Seven days later, Powell finally got his first Olympic medal as he anchored the Jamaican 4 × 100 m relay team to victory, helping establish a new world record in the process. His split time was recorded at 8.70 s (USATF High Performance Registered Split Analysis), bettering his previous record of 8.84 s set in Osaka, 2007. This is the fastest electronically timed anchor run in history, as Bob Hayes was hand timed as running between 8.6 and 8.9 seconds in the 1964 Olympics. The gold medal was later vacated by the IOC in 2017 when a retest of teammate Nesta Carter found the presence of the prohibited substance methylhexaneamine.

On 2 September 2008, Powell ran a new personal best of 9.72 s in the 100 m with windspeed measured at +0.2 m/s. He accomplished this feat at the Athletissima Grand Prix in Lausanne, Switzerland. After the run, he said that Bolt's record performance at the Olympics had inspired him to target a time of 9.59 s:

Powell was optimistic about his future chances on the track, and philosophical as to why he could not peak in past major championships:
