Kenya's Olympic marathon champion Eliud Kipchoge set a sensational world record over the distance on Sunday, shaving more than a minute off the previous best with a dazzling run in the German capital, to land the one major running accomplishment that had eluded him.
The 33-year-old, widely seen as the greatest marathon runner of the modern era, ran an official time of time of two hours, one minutes and 39 seconds on a sunny and warm autumn day along the flat inner-city course to beat Dennis Kimetto's world best by a minute and 18 seconds in Berlin back in 2014.
"I lack words to describe this day," said a beaming Kipchoge, a former world champion over 5,000-metres and marathon gold medallist at the Rio de Janeiro Olympics in 2016. "I am really grateful, happy to smash the world record.
"They say you can miss it twice but not third time. So I want to thank everyone who has helped me," Kipchoge, who last year took part in the Nike Breaking Two project, where he ran two hours and 25 seconds with the aid of "illegal" in and out pacemakers.
He started off with a sizzling pace and quickly shook off his biggest opponent, Wilson Kipsang, to make it a one-man race.
It was clear after the opening few kilometres that Kipchoge's only opponent would be the clock and his three pacemakers were pushed to the limit to keep the tempo high.
But even after the last one peeled off after 25-kilometres, Kipchoge showed no sign of slowing, passing the 30km mark in 1:26:45, with a pace of 2:52 per 1,000-metres.
"It was hard. I ran my own race, I trusted my trainers, my programme and my coach. That's what pushed me in the last kilometres," he said.
Kipchoge kept up the pace to sprint through the Brandenburg Gate and complete a world record run that cements his reputation as one of the greatest runners of all time.
