Mo Farah stumbled his way into the World Championships 5000 metres final on Wednesday, in a dramatic finale.
Defending champion Mo Farah overcame a stumble in his World Championships 5000 metres heat in Beijing on Wednesday to qualify for the final.
Farah went to the lead with about two laps to go at the Bird's Nest, stumbled about 150m out from the finish but kept his feet to finish second in a time of 13 minutes, 19.44 seconds behind Ethiopia's Yomif Kejelcha (13:19.38).
The Briton, 32, is eyeing yet another 5km/10km double at a major event having already wrapped up the latter on Saturday - the first leg of a sweep he completed at the 2013 championships in Moscow, and also at the London Olympics in 2012.
"I just managed to stay up again. In the final of the 10,000 it nearly happened, and then now, it almost happened in the last 100 metres," Farah told Eurosport post-race.
"Somebody just caught my leg, and I almost went down. I managed to just hold my feet."
Canada's Mohammed Ahmed, third over the line, survived a protest to hold his spot in the final, after being considered at fault for Farah's stumble - with the former pushing heat winner Kejelcha into the reigning Olympic and world champion.
Farah's heat was clearly the quickest, with another Ethiopian winning the other - Hagos Gebrhiwet qualifying with a time of 13:45.00.
Defending women's 800m champion Eunice Jepkoech Sum won her heat in 1:59.67 - one of seven competitors to break two minutes.
Belarus' Marina Arzamasova won the fastest heat in 1:58.69.
David Oliver's title defence in the men's 110m hurdles began in lightning fashion, the American setting a blistering 13.15secs.
Bronze medallist in Moscow, Sergey Shubenkov was third in his heat in 13.31secs to comfortably qualify for the semi-finals - the heat won by Olympic champion Aries Merritt (13.25secs).
Third at London 2012, Jamaica's Hansle Parchment won his heat in 13.33secs.
Cuban Pedro Pichardo set the pace in the triple jump with a mark of 17.43m, while Poland's Anita Wlodarczyk bid to regain the hammer throw title started well as she threw a 75.01m effort.
Wlodarczyk won the 2009 title in Berlin, but had to settle for silver in London and Moscow.
