Career Highlights: Hurdler Dai Greene is an Olympic gold away from holding the full set of major championship gold medals. A football player at youth level, Greene was offered a contract by Swansea City at the age of 16 but turned his back on the opportunity in favour of a career in track and field. After success on the junior circuit, he missed out on qualification for the Beijing Olympics due to a foot injury, but recorded a first senior win in 2009 and went on to reach the final of the 400m hurdles and pick up a 4x400m relay silver medal at the World Championships in Berlin later that year. 2010 proved the year that Greene announced himself as a major contender in the sport, picking up a European Championship gold in Barcelona before adding a second major gold of the season at the Commonwealth Games in Delhi. One of the medal outsiders going into the 2011 World Championships in Daegu, Greene overtook the field in the final straight to claim world gold and ensure he will be one of Britain’s hopes for a track and field medal in London. American trio Angelo Taylor, Kerron Clement and Bershawn Jackson earned the USA a clean sweep in Beijing and are likely to be the main threats to Greene four years on in the hurdles, while a medal in the relay is also a possibility.
