Commonwealth Games at Glasgow: Sports stars in focus

Jamaica's Usain Bolt is the arguably the biggest name in world sport and his presence in Glasgow, solely in the 4x100m relay, is a huge boost for the Commonwealth Games. The 27-year-old six-time Olympic gold medalist and double sprint world record holder ensures that the world media's attention will be focused on Scotland. Fans will only be hoping that he might still be able to really light up the Games.

David Rudisha: The 800m world record holder has made an impressive long-awaited return from injury, clocking the world's fastest two laps this season at no lesser place than Glasgow. That appearance was Rudisha's first since he stormed to his world-record setting Olympic gold medal showing in London in 2012, covering 800m in just over 101 seconds.

Mohammed Farah: Somali-born athlete stormed to British acclaim when he won both the 5,000 and 10,000m at the London Olympics, becoming one of the "local" faces that helped set the Games out as one of the most successful ever. After an eighth place in London, he stepped back in distance and Glasgow breathed a sigh of relief.

Sally Pearson: The Australian is rumoured to be going for a double in Glasgow, in her usual 100m hurdles and also the 100m flat. Coming back from injury, the 27-year-old Queenslander has at times struggled this season, but will be wanting, perhaps, to better her outing over 100m in New Delhi four years ago, where she was stripped of the title for a dubious false-start on appeal.

DJ Forbes: The 31-year-old has been with the all-conquering New Zealand rugby sevens team since 2006, the shaven-headed flanker a stalwart of Gordon Tietjen's squad that has so far won all four Commonwealth Games titles and dominated the IRB world circuit throughout. Forbes' abrasive defence ties in perfectly with a great linking and supportive game that makes the All Blacks tick, more often to

Nicola Adams: The young Britain won the first ever Olympic women's boxing gold medal at the London Games in 2012 when she defeated China's world champion Ren Cancan. Adams started boxing at the age of twelve. In 2007, she was the first ever English female to earn a medal in a major tournament when she won silver in the European Championships.

Alicia Coutts: The 26-year-old swimmer has won 21 medals for Australia in major championships over the past four years. That haul included five medals at the 2012 Olympics including one gold. At the 2010 Commonwealth Games in Delhi, Coutts was the most decorated swimmer winning gold in the 100m freestyle, 100m butterfly, 200 individual medley, 4x100m freestyle relay and 4x100m medley relay.

Nicol David: The 30-year-old seven-time world champion and global number one David completed her collection of major international titles with Commonwealth Games gold in Delhi. In Glasgow, Nicol will also be out to win Malaysia's first medal in the women's doubles . She once also enjoyed a 13-month, 51-match winning streak, from March 2006 until April 2007.

Anna Meares will be defending her 500m time trial and individual sprint titles in Glasgow and equal fellow cyclist Kathy Watt's Australian record of competing at four Commonwealth Games. The 30-year-old from Queensland is also a two-time Olympic gold medallist having won the 500m time trial in 2004 and sprint at London eight years later.

The 34-year-old Bradley Wiggins made history in 2012 when he became the first British rider to win the Tour de France before going on to take the gold medal in the Olympics time trial. He had already won three track gold in the 2004 and 2008 Olympics. Knighted for his services to the sport, his record didn't guarantee him a place at the 2014 Tour de France when he was dropped by his Sky team.
