David Rudisha proved to doubters that he is still king over 800m as Kenya increased their lead at the top of the medals table in Beijing.
Kenyans made it onto the podium three more times to follow their magnificent Monday evening’s haul and now have nine medals, including four golds, with Britain and Jamaica a distant second and third on the ladder.
Rudisha and new 400m hurdles sensation Nicholas Bett claimed gold with Faith Kipyegon adding a brave and battling silver during a memorable final 40 minutes for the nation on day four of the championship.
The 26-year-old Olympic Champion Rudisha claimed his second world title by dominating throughout the two-lap race to win comfortably in a time of 1:45.84 seconds.
He pulled teammate Ferguson Rotich around with him for 700m before Poland’s Adam Kszczot forced his way past and took up the chase.
Rudisha, so often suspect down the home straight recently, made no mistake this time and, with Nijel Amos, who has beaten him in six straight races since the 2012 Olympic Final, being eliminated in the semi-finals, there was no-one who could match the world record holder.
Rotich fell away and in the final 25 metres was relegated out of the medal positions by Boznia and Herzegovina runner Amel Tuka.
The Kenyan trials winner crossed the line a distraught fourth and strode straight past waiting journalists to the changing rooms in his obvious disappointment.
Earlier Bett, a 23-year-old former 110m hurdler, stretched Kenya’s track diversity further than ever before by taking a sensational and record shattering gold over the longer, lower hurdles.
His time of 47.79 destroyed Erick Keter’s 22-year old national record (48.24) while lowering his own lifetime best by exactly half a second.
