David Rudisha claims World Championships gold

Olympic champion David Rudisha has claimed his second 800m world title with success at the Bird's Nest Stadium in Beijing.

The Kenyan entered the race as favourite and put in a dominant performance, leading all the way to finish in a time of 1:45.84 at the World Athletics Championships.

Rudisha has suffered an injury-ravaged three years since his world-record time at the London Olympics three years ago, while he was only 14th fastest overall in the semi-finals but qualified due to winning his heat.

Poland's Adam Kszczot came home in second place with a time of 1:46.08 to claim silver, but he never truly troubled the world champion.

Amel Tuka of Bosnia and Herzegovina, meanwhile, won his country's first ever medal at a World Championships by finishing in third, edging out Ferguson Cheruiyot Rotich of Kenya.
