After 2013 world silver medallist Conseslus Kipruto towed the field through the first kilometre in 2:49.50 and then increased the pace slightly to reach 2000m in 5:36.77.
With 30m to go, it was Kemboi, at 33 the oldest man in the field, who again found a change of gear and he crossed the line in 8:11.28, before pointing at his head with both hands to indicate that he was still the boss.
Conseslus Kipruto, still only 21, took his second successive silver medal in 8:12.38 while the ‘other’ Kipruto – Brimin Kiprop – returned to the podium in third place.
The only slight surprise was that Jairus Birech, the fastest man in the world for the past two years and 2014 Diamond Race winner, was edged out of the medals.
However, Birech’s fourth place finish meant that not only had Kenya got a clean sweep of the medals for the third time ever in this event but they also filled the first four places, a feat only achieved twice before in IAAF World Championships history – by the USA in the 2005 men’s 200m and Ethiopia in the women’s 5000m the same year.
