Greene is one of Great Britain's gold medal hopes at the 2012 London Olympics

Dai Greene has certainly set the gold standard for British athletes preparing for the 2012 Olympic Games in London.

The 25-year-old was already Commonwealth champion when the Welsh 400m hurdler showed his trademark great grit and determination to dominate the worlds in Daegu.

Greene was one of just two British athletes to celebrate glory at the 2011 World Championships as he battled past Puerto Rico's Javier Culson after the final hurdle to win in a time of 48.26 seconds.

"It was all the hard work coming together in that one moment," said Greene.

"I felt I had achieved my mission."

The Swansea Harrier added to his world title when he claimed the Diamond League crown as Greene showed why he is a gold medal hope for Britain's home Olympics..

"I want to win as many major medals as I can," said Greene.

"After 2010 being European and Commonwealth champion, I felt the next step was to take on the best in the world. And I felt it was within my grasp.

"But I don't think about the magnitude at what I'm trying to achieve."

Greene's scintillating run ensured he became just the second Welshman since Colin Jackson, the 110m hurdler who ruled the world in 1993 and 1999, to be crowned champion of the world.

His victory was the first British gold in South Korea and he lifted a Team GB squad preparing for the 2012 Olympics.

And should he win in London, Greene would become just the fifth British athlete alongside Linford Christie, Daley Thompson, Jonathan Edwards and Sally Gunnell to win all of athletics' major medals.

Greene will also bid to become the first Welsh Olympic champion in track and field since long-jumper Lynn Davies won gold at the Tokyo Games in 1964.
