STEPHEN KIPROTICH stunned the Kenyan favourites to win a shock marathon gold.
The Ugandan rank-outsider surged away from early breakaway leader Wilson Kipsang to clock a fine 2hours 8mins 1secs – cheered on by huge crowds in searing London heat.
Two-time world champion Abel Kirui took silver in 2:08.27, with his tiring fellow Kenyan Kipsang third.
Kiprotich said: “Since 1972 Uganda has not won a gold medal so we’re very happy.”
In fact, it was only his country’s second ever gold – after John Akii-Bua won the 400m hurdles in that Munich Games of 40 years ago.
And the east African nation’s sole other medal was a bronze from 400m runner Davis Kamonga in 1996.
Brazilian Franck De Almeida went through 10km in 30:38 in a race billed as a battle between Kenya and Ethiopia.
But the Ethiopian team’s tactics were dealt an early blow as Dino Sefir fell well off the pace, as Kipsang reeled in the Brazilian pace setter.
Kipsang, the 2012 London Marathon winner then built up a lead on the peloton, going through the halfway mark in 1:03.15, 16sec ahead of the chasing pack.
The Kenyan built that lead up to 30sec on the stunning course, designed to take in as many of the British capital’s main sights as possible.
By the 23km mark in sweltering conditions, a second Ethiopian, Getu Feleke, was beginning to flag and had fallen off the chasing pack’s pace.
In front of thousands of spectators packed 10-deep in some places, Kiprotich set off in pursuit of Kipsang, splintering the pack in the hunt for a podium place.
Kirui and Ethiopia’s Dubai marathon winner Ayele Abshero followed, and the trio cut Kipsang’s lead to just 11sec, and then pulled level at 25km.
Abshero struggled to stay level and dropped 36sec by the 30km stage, Brazilian Marilson Dos Santos overtaking him into fourth.
As the leading trio went through the gilded, covered Leadenhall Market for the final time with 7km to go, the Kenyans upped the pace to shake off Kiprotich.
Japan’s Kentaro Nakamoto and the sole American left in the field, Eritrean-born Meb Keflezighi, were in position to challenge for a podium should anyone hit the wall in the final few miles.
But up front, the two Kenyans were caught napping as Kiprotich showed a dramatic change of pace to surge to the front in an audacious ambush at 32km, and was quickly 200m ahead.
Kiprotich, who has moved to the famed Eldoret region of the Kenya’s Rift Valley to train with former world 5000m champion Eliud Kipchoge, accelerated away, a brief look back over his shoulder confirming his position at the head of the field.
Going into the final 2km, the 23-year-old Ugandan was 20sec ahead of Kirui.
And he had enough time to grab an Ugandan flag on his last time entering the Mall, in the shadow of Buckingham Palace, draping it around his shoulders as he crossed the line for a convincing victory.
