A little over a month after Ugandan Joshua Cheptegei set the road 10k world record of 26:38 in Valencia, Spain, on Dec. 1, Kenyan Rhonex Kipruto bettered the mark on Sunday with his 26:24, also in Valencia. He won the 10k Valencia Ibercaja race by 48 seconds over Bernard Kimeli.

The 20-year-old blitzed through the halfway point in 13:18, a lowering itself of the 5k road world record. Kipruto’s second-half was even faster, 13:06, but that split won’t count for record purposes according to World Athletics.

Of particular note to followers of the road racing scene is that Kipruto is an Adidas-sponsored athlete and thus was not wearing Nike’s controversial VaporFly shoes.

26:24 is an absurdly fast time that would be the fourth-fastest ever if done on a track. Only Kenenisa Bekele and Haile Gebrselassie have run faster for 10,000m.
