Kenya’s Farah became only the second man to achieve the double of world and Olympics 5,000 and 10,000 metres titles.
Farah, who won an emotional double gold at the Olympics last year in the Somalia-born athlete’s adopted home city of London, clocked 13min 26.98sec to
emulate Kenenisa Bekele’s double-double at the 2008 Beijing Olympics and 2009 Berlin worlds.
“It’s something I have worked very hard for. I was thinking about the kids and being away from them for so long,” said Farah, who trains under Alberto Salazar in Portland, Oregon.
Among the women, Jamaica’s Fraser-Pryce became only the third athlete to achieve the women’s world sprint double. The 26-year-old — who regained her 100m title on Monday — timed 22.17 seconds while 100m silver medalist Murielle Ahoure of Ivory Coast took another silver in a photo finish with Nigeria's Blessing Okagbare, both of whom timed 22.32.
Meanwhile, two-time defending champion Usain Bolt’s bid to seal a third successive world 200m title advanced smoothly as he coasted to victory in his semi-final in a comfortable 20.13sec.
