Kenya established a world record of 14:22.22* in the men's 4x1500m final, as Collins Cheboi, Silas Kiplagat, James Magut and Asbel Kiprop turned back challenges from Ethiopia and the USA before simply striding away from everyone else in history.
The quartet lowered the record by 14 seconds; not quite the precipitous drop seen in the women's race on Saturday but still a tremendous race. The Kenyans will take home an additional USD $50,000 world record bonus on top of their USD $50,000 first-place prize money.
It was the US team which handed off first, with Patrick Casey in the lead at the first exchange. The Kenyans – whose Cheboi had allowed Ethiopia's Mekonnen Gebremedhin to lead pretty much the entire first leg – did not allow this to stand, and Kiplagat set a more ambitious pace (3:32) on the second leg. He finally broke USA's David Torrence with 100m left in the leg.
With Magut now in charge, it was back to concentrating on the record, and the remaining question was whether Ethiopia could catch the USA, or indeed hold off a tough Australian quartet.
The last leg was up to world champion Kiprop, without a whole lot of doubt at that point that the record was going down. Kiprop was even a little startled to see Magut coming up to the third exchange and was barely ready to take the baton, but the bobble hardly mattered. Once he got going, Kiprop took the bell at 13:26.00 and closed in 56.22 to set the world record. Unchallenged, it wasn't even the quickest lap of the record. (Kiplagat's first full lap of 53.50 took that honour.)
After slipping back behind the Australians briefly, the Ethiopians did come up to make it a race for second, with national record-holder Aman Wote closing on the USA's Leonel Manzano to make a race for second. USA established a national record of 14:40.80 to hold on to second.
The Ethiopians also ran a national record, 14:41.22. Australia made it a full set of four records in 14:46.04, and Qatar, seventh in 15:10.77, also established a national record.
