Mo Farah outpaced a trio of Kenyan challengers to retain his IAAF World Championships 10 000 metres title in Beijing on Saturday.
The 32-year-old spent the majority of the race as part of a pack of five leaders, which also included his training partner Galen Rupp and Kenyans Geoffrey Kipsang Kamworor, Paul Kipngetich Tanui and Bedan Karoki Muchiri.
Farah sped up the pace in the final lap to leave the four trailing, and while the Kenyan trio attempted to follow; the Britain raced away to claim gold in a time of 27 minutes 01.13 seconds.
"I knew the guys were going to do that, too many years now they've left it slow so they had to do it and it did happen," Farah told the BBC.
"It was a matter of digging in there and hopefully it didn't take it too much out of me. It's not easy running 27 minutes in this heat."
Kamworor claimed silver in a time of 27:01.76, while Tanui was third in 27:02.83. The victory gave Farah his fifth medal at the World Championships and his fourth gold.
Farah can claim another medal on August 29 should he qualify for the final of the 5000 metres.
"I've got to recover, do everything that I can and hopefully get ready for the 5,000m," Farah added.
He will become the first man to win both the 10 000 and 5 000 metres at consecutive World Championships if he is successful.
