Kenya's Rhonex Kipruto set a new 10km road world record of 26 minutes 24 seconds in Valencia on Sunday. Kipruto bettered the previous fastest time set by Uganda's Joshua Cheptegei, also in Valencia last month, by 14 seconds.
Both times are pending official ratification.
The astonishing run by Kipruto also included him breaking the 5km road world record after he crossed the halfway point of the 10km race in 13:18.
Kipruto came close to breaking the Kenya's Kipruto breaks 10k world record in Valencia 10km world record when he registered 26:44 in Prague in September 2018.
