Uganda’s world 10,000m champion Joshua Cheptegei has broken the 5km road world record by 27 seconds in Monaco.
The 23-year-old ran 12 minutes 51 seconds to smash the previous record, set by Kenya’s Rhonex Kipruto en route to victory at January’s Valencia 10k.
“I had sub-13 minutes in my mind so when my legs felt good I decided to really go for it,” said Cheptegai.
France’s Jimmy Gressier finished second in Monaco with a European record of 13:18.
Nick Goolab finished third in a new British record of 13:27, the Belgrave Harrier bettering the mark held jointly by Mo Farah and Rob Denmark by three seconds.
