The Honourable Usain St. Leo Bolt, OJ, C.D. ( /ˈjuːseɪn/; born 21 August 1986), is a Jamaican sprinter and a five-time World and three-time Olympic gold medalist. He is the world record and Olympic record holder in the 100 metres, the 200 metres and (along with his teammates) the 4×100 metres relay. He is the reigning Olympic champion in these three events, and is one of only seven athletes (along with Valerie Adams, Veronica Campbell-Brown, Jacques Freitag, Yelena Isinbayeva, Jana Pittman, Dani Samuels) to win world championships at the youth, junior, and senior level of an athletic event.

Bolt won a 200 m gold medal at the 2002 World Junior Championships, making him the competition's youngest-ever gold medalist at the time (since surpassed by Jacko Gill). In 2004, at the CARIFTA Games, he became the first junior sprinter to run the 200 m in less than 20 seconds with a time of 19.93 s, breaking the previous world junior record held by Roy Martin by two-tenths of a second. He turned professional in 2004, and although he competed at the 2004 Summer Olympics, he missed most of the next two seasons due to injuries. In 2007, he broke Don Quarrie's 200 m Jamaican record with a run of 19.75 s.

Jonathan Stephen Ross, OBE (born 17 November 1960) is an English television and radio presenter, best known for presenting the BBC One chat show Friday Night with Jonathan Ross from 2001 until he left the BBC in 2010. Ross began hosting a new chat show on ITV1 starting 3 September 2011. Ross also hosted his own radio show on BBC Radio 2, and acted as a film critic and presenter of the Film programme. Other regular roles have included being a regular panellist on the comedy sports quiz They Think It's All Over from 1999 to 2006, and presenting the annual British Comedy Awards from 1991 to 2007, and 2009 onwards.

Ross began his television career as a programme researcher, before débuting as a television presenter for The Last Resort with Jonathan Ross on Channel 4 in 1987. Over the next decade he had several radio and television roles, many through his own production company, Channel X. In 1995 he sold his stake in Channel X, and embarked on a career with the BBC. In 1999, Ross took over presenting the Film programme from Barry Norman, and also began presenting his own radio show, while two years later he began hosting Friday Night with Jonathan Ross. For the chat show, Ross won three British Academy of Film and Television Arts (BAFTA) awards for Best Entertainment Performance, in 2004, 2006 and 2007. By 2006 Ross was believed to be the BBC's highest paid star. In 2005, Ross was made an Officer of the Order of the British Empire (OBE) for services to broadcasting. Ross has been involved in controversies throughout his broadcasting career. As a result, in 2008 he wrote a semi-autobiographical work titled Why Do I Say These Things?, detailing some of his life experiences.

Yohan Blake (born December 26, 1989) is a Jamaican sprinter and the current 100 metre World Champion. He holds the national junior record for the 100 metres, and is the youngest sprinter to have broken the 10-second barrier (at 19 years, 196 days). Blake's personal best of 9.82 seconds makes him the fourth fastest Jamaican runner, after Nesta Carter, Asafa Powell and Usain Bolt. His fastest run under any conditions is 9.80 seconds in May 2011 in Kingston, but the wind assistance (+2.2 m/s) was over the legal limit. He is coached by Glen Mills, and is training partners with Bolt and Daniel Bailey. On September 16, 2011 in Brussels, Belgium, he won in a time of 19.26 seconds, the second fastest 200 m ever.

Born in St. James, Jamaica, Blake is the son of Veda and Shirley Blake. He attended St. Jago High School in Spanish Town.

Blake set the fastest time by a Jamaican junior sprinter over 100 m with 10.11 seconds. The record was set at the 2007 CARIFTA Games held in the Turks and Caicos islands where he also led his team to gold in the 4 × 100 metres relay. At this occasion, he was awarded the Austin Sealy Trophy for the most outstanding athlete of the 2007 CARIFTA Games.

Justin Gatlin (born February 10, 1982) is an American sprinter. He is an Olympic gold medalist, with a 100 m personal best of 9.85 seconds and two-time World indoor champion in the 60-meter dash. He served a four-year ban from track and field for testing positive for a banned substance; Gatlin had appealed the ban in 2009, but it was later denied.

Gatlin attended Woodham High School in Pensacola, Florida.

In the fall of 2000, Gatlin arrived at University of Tennessee, Knoxville, as a good high school 110 m hurdler. During high school, Justin was recruited for track by coaches Vince Anderson and Bill Webb who quickly realized his potential and turned him into a sprinter. After training and competing in UT's program for two years under the guidance of former Tennessee assistant Vince Anderson, Gatlin won six consecutive NCAA titles. In the fall of 2002, Gatlin left Tennessee after his sophomore season to join the professional ranks. Just two years later, he won the gold medal in the 100 m (9.85 s) at the 2004 Summer Olympics, narrowly beating Francis Obikwelu of Portugal and the defending champion Maurice Greene. He also won a bronze medal in a USA sweep of the 200 m race, and a silver medal as a member of the 4 x 100 m relay squad. In the 2005 World Athletics Championships in Helsinki, he again triumphed over 2003 champion Kim Collins, capturing the gold medal in the 100 m.
