Mo Farah relieved to reach 5,000m final after stumble

History-chasing Mo Farah has admitted his relief over reaching the men's 5,000m final at the World Athletics Championships after a brief stumble in this morning's heat.

The reigning champion's bid for a historic 'triple-double' looked momentarily in doubt after the 32-year-old was clipped during the final 150 metres in Beijing.

However, he kept his balance and his hopes of history alive by ultimately qualifying for Saturday's final in second place, with a time of 13:19.44.

"I'm very lucky I stayed up," he told BBC Sport afterwards. "I just held my balance. At that point you just have to stay on your feet and chill out."

Having won two gold medals apiece at London 2012 and Moscow 2013, Farah - who retained his 10,000m crown this week - is vying to become the first runner in history to achieve a 'triple-double'.

He will be joined in the final by compatriot Tom Farrell, who advanced from his heat in fourth position earlier this morning.
