Olympics 2012: Team GB athletes at London Games Day 12

Great Britain failed to add to their medal tally on Day 12 of the London Games.

It was the first time since Day One that Team GB were unable to win a medal in what has been an otherwise successful Olympics.

They finished the previous day with a total of 48 medals - the best performance by British athletes for more than a century - and remain third in the medal table despite a barren Wednesday.

Despite a day without a medal, a number of British athletes have guaranteed themselves podium places, while others have given themselves a chance of winning Olympic gold, silver, or bronze.

Boxer Nicola Adams is guaranteed at least a silver after reaching the final of the women's flyweight competition, while sailors Hannah Mills and Saskia Clark are also certain to win a medal after a strong performance in the women's 470 class.

Here is a a sport-by-sport round-up of how every Team GB athlete performed on Day 12 of the 2012 Olympic Games in London.

ATHLETICS

Lisa Dobriskey qualified automatically from her 1500m semi-final with a time of 4:05.35. Hannah England , in the same race, finished ninth and did not make Friday's final. Laura Weightman , coached by 1500m silver medallist Steve Cram, grabbed a personal best of 4:02.99 and qualified for the final with a photo finish.

Lawrence Clarke misses out on a medal after finishing fourth in the men's 110m hurdles final.

Andy Turner comes fourth in his semi, and his time of 13.42 seconds is not enough to reach the final.

Desperate news for GB decathlete Daniel Awde as a knee injury forces him to pull out of the decathlon competition. Awde had set a modest distance of 6.83m in the long jump after failing with his first two attempts. He earlier achieved a new personal best of 10.71 seconds to win his 100m heat.
