Ugandaâ€™s Joshua Cheptegei shattered the 5km road world record in Monaco on Sunday, shaving 27 seconds off the mark set by Kenyaâ€™s Rhonex Kipruto last month.
Cheptegei, the 10,000m world champion, crossed the finish line in 12 minutes and 51 seconds in his first race of the year to eclipse Kiprutoâ€™s effort from the 10K Valencia Ibercaja in Spain last month.
Kipruto had set the mark en route to the 10km road world record.
â€œWow, this is really great. I had sub 13 minutes in my mind today so when my legs felt good during the race, I really decided to go for it,â€ the 23-year-old Cheptegei said.
â€œTo take this many seconds of the record makes me very happy and is a great first test for me in an important season.â€
Frenchman Jimmy Gressier finished second in Monaco with a time of 13:18 to beat the European record of 13:29 set by Julien Wanders in the same race last year.
