World Athletics Championships 2011 - in pictures

The UK Athletics chief Charles van Commenee said before the start of the World Champs that he hoped Britain would bring back at least seven medals from Daegu. But when Christine Ohuruogu was disqualified for a false start in the women's 400 metres heats during day one, it was an inauspicious start for the team Photograph: Stu Forster/Getty Images

The following day Dwain Chambers was also axed from the men's 100m semi-finals for a false start. New rules imposed at the championships this year meant that athletes were not given second chances if they jumped the gun Photograph: Ian Walton/Getty Images

Usain Bolt was the outright favourite in the men's 100m final and was looking to complete the hat-trick of titles he achieved in Berlin two years ago and Beijing in 2008 ... but the crowd gasped as Bolt broke from the blocks too soon Photograph: Kim Kyung-hoon/Reuters

Bolt was aghast at his mistake but, after briefly venting his frustration with himself, he took the blow with good grace and vowed not to let it affect his remaining events. His compatriot Yohan Blake went on to win the 100m gold in a time of 9.92 seconds Photograph: Peter Parks/AFP/Getty Images

Britain had to wait until day six of the tournament to win a gold medal. It was scooped by Dai Greene, who powered down the home straight to beat rivals Cornel Fredericks of South Africa, Aleksandr Derevyagin of Russia and Angelo Taylor of United States in the men's 400 metres hurdles final Photograph: Andy Lyons/Getty Images

Oscar Pistorius competed in both the 400m individual and relay events. His performance in the individual event was far short of the mark required to make the final, but he contributed to the success of the relay team in the qualifying rounds.

Bolt made amends for his elimination in the 100m with a dominant display in the 200m. The Jamaican was cautious out of the blocks in the final but still won by a distance in a time of 19.40 seconds - the fourth fastest 200m time ever Photograph: Mark Dadswell/Getty Images

Phillips Idowu jumped well in the men's long-jump on the ninth and final day of the championships, but he was outdone by a monstrous effort from the American Christian Taylor who recorded the fifth biggest jump in history Photograph: Stu Forster/Getty Images

Mo Farah claimed a second gold medal for Britain in the men's 5,000m to end the tournament on a high. Britain finished with the seven medals Van Commenee had targeted - 2 gold, 4 silver, 1 bronze Photograph: Alexander Hassenstein/Bongarts/Getty Images

The final event of the tournament was the 4x100m relay race which was won in spectacular fashion by the Jamaican team, including Bolt.
