Steve Mullings (born 28 November 1982) was a sprint athlete who specialized in the 100 and 200 metres events.

Mullings began his international athletics career with a bronze medal win in the 100 m at the Pan American Junior Championships. At the 2004 national championship he made his first impact in senior athletics, setting new bests of 10.04 and 20.22 in the sprints, and finishing as the 200 m national champion. This earned him qualification into the 2004 Summer Olympics, but he was withdrawn from the competition after his sample from the national championships tested positive for banned substances. After his B sample also tested positive for testosterone, he was banned from competition for two years and his results between mid-2004 and 2005 were removed from the record.

He returned to competition in 2006 but finished the season with unimpressive bests of 10.31 and 20.54. The following year was much more successful. He won the 100 m in Zaragoza with a wind-aided (3.7 m/s) run of 9.91 seconds, and featured on the 2007 IAAF Golden League circuit. He competed at the 2007 World Championships in Athletics as a heats runner for the Jamaican silver medal-winning 4×100 metres relay team.

Tyson Gay (born August 9, 1982) is an American track and field sprinter. His primary events are the 100 meters and 200 meters. His personal bests establish him as the second fastest athlete in the 100 meters and the fifth fastest athlete in the history of the 200 meters, with times of 9.69 (which is a United States record) and 19.58 seconds respectively.

Gay has won numerous medals in major international competitions, including a gold medal sweep of the 100 m, 200 m and 4 x 100 meters relay at the 2007 Osaka World Championships. This made Gay the second sprinter to win all three events at the same World Championships, after Maurice Greene.

At the same meet, Gay suffered a severe hamstring injury in the 200 m event. The injury persisted and this contributed to his failure to win a single medal at the Beijing Olympics. As a participant in the US Anti-Doping Agency's "Project Believe" program, Gay is regularly tested to ensure that his system is clean of performance-enhancing drugs.

Gay also holds the record for the fastest non-winning time for the 100 meters. In August 2009, he ran 9.71 seconds in the World Athletics Championships from Berlin, Germany. Tyson Gay remains the only sprinter to have defeated Usain Bolt in a final since Bolt made his first world record run. Gay ran a wind assisted 9.68 at the 2008 US Olympic trials.

Richard William Duncan Pound, OC OQ (born March 22, 1942) is a Canadian lawyer, partner of the law firm Stikeman Elliott, the former president of the World Anti-Doping Agency (WADA) based in Montreal, and former chancellor of McGill University. He is a former vice-president of the International Olympic Committee (IOC) and was a one-time candidate for the presidency of that organization.

Born in St. Catharines, Ontario, Canada, Pound was a swimming competitor at the 1960 Summer Olympics. He finished sixth in the 100 metre freestyle and was also on Canada’s fourth place relay team. He would later win a number of medals at the 1962 Commonwealth Games. Retiring from swimming, he accepted a role with the Canadian Olympic Committee and eventually became its president.

In 1978, he was elected to the International Olympic Committee and put in charge of negotiating television and sponsorship deals. Pound revolutionized the Olympic movement using such deals to transform the IOC into a multi-billion dollar enterprise. He became known as an outspoken critic of corruption within the IOC, while at the same time supporting the leadership of IOC President Juan Antonio Samaranch. His criticisms were given a wide airing after the scandals surrounding the Salt Lake City Olympics broke, and he was then appointed head of the inquiry into the corruption. He also campaigned vehemently for stronger drug testing.

Nickel Ashmeade (born April 7, 1990) is a Jamaican sprinter who specialises in the 100 and 200 meters.

Ashmeade first enjoyed success in the sprints as a junior athlete: at the 2006 Central American and Caribbean Junior Championships he beat compatriot Dexter Lee to the 100 m title, was runner-up to Ramone McKenzie over 200 m, and teamed up with the pair to bring Jamaica the 4×100 meter relay title. Another medal haul came for the young Jamaican at the 2007 World Youth Championships in Athletics, where he was second to Lee in the 100 m, ran a 200 m best of 20.76 seconds for the bronze medal, and helped the national team to another bronze in the sprint medley relay. He competed at the Penn Relays in 2008 and represented his school, St. Jago High School – an institution renowned for producing track and field athletes.

Ashmeade focused on the 200 m at the 2008 World Junior Championships in Athletics and he took the silver medal, narrowly finishing behind France's Christophe Lemaitre. A second silver came in the 4×100 m relay and he departed from his usual oeuvre to help Jamaica to fourth place in the 4×400 m relay. The regional CARIFTA Games provided him the opportunity for further junior medals: he won the 200 m title and two relay gold medals at the 2008 edition and almost repeated the feat in 2009, with the sole difference being a 4×400 m relay silver. His final international outing as a junior athlete came at the 2009 Pan American Junior Athletics Championships in Port of Spain and he won the 200 m gold in a personal best of 20.40 seconds before going on to take a relay bronze medal.

Asafa Powell CD (born 23 November 1982) is a Jamaican sprinter who specialises in the 100 metres. He held the 100 m world record between June 2005 and May 2008, with times of 9.77 and 9.74 seconds respectively. Powell has consistently broken the 10-second barrier in competition, with his personal best of 9.72 s being the fourth fastest time in the history of the event. As of 2nd May 2012, Powell has broken the ten-second barrier legally more times than anyone else – 74 times in total.

Powell competed in the 100 m at the 2004 Athens Olympics and the 2008 Beijing Olympics but failed to convert his success to the world stage, finishing fifth both times. However, in Beijing with the Jamaican team he won a gold medal and set the world and Olympic record in the 4 × 100 metres relay. At the 2007 Osaka World Championships he won a bronze and a silver medal in the 100 m and 4 x 100 m relay respectively and he has been successful at the Commonwealth Games, winning two gold and one silver medal. At the 2009 World Championships he won 100 m bronze and a relay gold. Powell has won five times at the IAAF World Athletics Final and is the 100 m record holder for the event.
