Veteran Spanish racer Joan Llaneras is favored for a medal in his final Olympic Games competition. A gold medalist at the Sydney 2000 Olympic Games and silver medalist in Athens four years later, Llaneras remains a medal threat despite entering the last Men's Points Race of his career at age 39.

Vasili Kiryienka of Belarus is a top threat after winning the gold medal in the Manchester 2008 World Track Cycling Championships in March.

Defending Olympic champion Mikhail Ignatyev of Russia is expected to rise to the occasion despite a recent focus on Road Cycling.

Men's Individual Pursuit

Eight riders from qualifying on Friday, 15 August will square off in the first round to race for one of four berths in the medal rounds.

Defending Olympic and three-time world champion Bradley Wiggins of Great Britain is the man to watch after riding an Olympic record 4:15.031 in qualifying on Friday.

Wiggins is trying to become the first cyclist to repeat as Individual Pursuit gold medalist at the Olympic Games since it was introduced as an event in 1964.

Hayden Roulston of New Zealand set the second-best time in qualifying to position himself well to earn New Zealand's second ever Olympic medal in Men's Individual Pursuit.

Taylor Phinney of the United States qualified seventh to make the first round as the youngest competitor at 18. The son of American Olympic medalists and ex-racers Davis Phinney and Connie Carpenter-Phinney, he finished eighth in the Manchester world championships in March.

Men's Keirin

After qualifying rounds, six cyclists will face off in the final medals race.

Great Britain's Chris Hoy is the king of the Keirin, winning back-to-back world titles in 2007 and 2008. Hoy dominated the event in last season's World Cup, winning all three races he started and clinching the overall World Cup Keirin crown.

Hoy was key to Great Britain's gold medal in the Men's Team Sprint on Friday, 15 August.

Theo Bos of the Netherlands has been Hoy's toughest rival, winning the 2006 world title and finishing as runner-up in 2007.

Also from the Netherlands, Teun Mulder was silver medalist at the 2008 Manchester World Track Cycling Championships and was the 2005 world champion.

Women's Individual Pursuit Final Round

Eight riders from Friday, 15 August qualifying will vie for four berths in the final medals race on Sunday, 17 August.

Wendy Houvenaghel of Great Britain, who has never won a medal in world championship or Olympic competition, was fastest in qualifying to position herself as an outsider for the gold medal.

Great Britain's Rebecca Romero was second-fastest in qualifying. The defending world Women's Individual Pursuit champion is hoping to become the first British athlete to win an Olympic medal in two different Summer Games events. She won a silver medal in the Quadruple Sculls in Rowing at the Athens 2004 Olympic Games.

American Sarah Hammer won back-to-back world titles in 2006-07, but struggled to fifth in qualifying.
