Britain's Mo Farah makes history with 'triple double' in athletics
5,000m victory in Beijing seals distance titles at consecutive world championships and the London Olympics; American Ashton Eaton breaks his own world decathlon record
Mo Farah became the first man to win back-to-back world distance doubles when he stormed to a 5,000 metres victory in Beijing on Saturday.
The Briton, rocked this season by doping allegations against his coach, put the row behind him as he produced a devastating final 80 metres to romp home in 13 minutes 50.38 seconds.
Kenyan Caleb Ndiku, in 13:51.75, held on for silver after making a valiant break with 800m to run. Ethiopian Hagos Gebrhiwet took bronze.
Olympic decathlon champion Ashton Eaton produced a lung-busting 1,500m race to break his own world record to retain his world title.
The American threw a season's best 63.63 metres in the javelin before clocking four minutes, 17.52 seconds in the 1,500m to finish with a new world best total of 9,045 points, eclipsing his previous mark by six points.
Canada's Damian Warner took silver behind Eaton, posting a national record of 8,695 points and German Rico Freimuth the bronze with 8,561.
