Britain's last hope of a medal - and it was a very slim one - ended when the men's 4x400m relay team, who have enjoyed great success at previous championships, were beaten into sixth place.

The quartet of Iwan Thomas, Jamie Baulch, Tim Benjamin - all Welsh - and Mark Richardson came home in 3:01.26 as the United States comfortably triumphed in 2:57.54.

The Bahamas quartet snatched the silver from their close rivals Jamaica by just 0.2secs with a time of 2:58.19.

Richardson revealed more injury woe on his behalf after the race which saw him bump into an American as he took off on the last leg.

He said he had hurt his Achilles once more and that he now faced a likely hernia operation as well.

"I'm just want to get my body right and do a winter's training.

Having the Commonwealth Games and European Championships to look forward to is nice."
