Walk gold for impressive Kirdyapkin
The Olympic record tumbled as Russia's Sergey Kirdyapkin took gold in the London 2012 Men's 50km Walk event on Saturday.
Kirdyapkin broke away from nearest challenger Si Tianfeng of China with 10km of the race remaining and went on to win the event with a time of three hours, 35 minutes and 59 seconds.
Tianfeng appeared set to take silver but a spirited performance from Australia's Jared Tallent saw him emerge as the surprise runner-up to the dominant Russian.
There was no glory on this occasion for Team GB, with Britain's only entrant Dominic King finishing last in 51st, though Ireland's Rob Heffernan was unlucky not to be better rewarded for a strong performance, eventually finishing fourth.
The Irishman appeared to be closing in on Tianfeng, who faded significantly in the latter stages of the event, but the Chinese athlete had just enough left in the tank to hold off the late challenge.
"I was really happy with how I did out there, but it is tough on anyone coming fourth," said Heffernan.
