A little over a month after Rhonex Kipruto took down Joshua Cheptegei’s road 10k world record, the Ugandan has answered back in a big way by running 12:51 on Sunday in Monaco to smash Kipruto’s 5k world record. Cheptegei cut a whopping 27 seconds off the 13:18 that the Kenyan ran on Jan. 12, a run that came en route to Kipruto’s 26:24 10k record.

As Kipruto proved when he ran the 26:24 last month, just seven seconds shy of the 10,000m track world record, road times are quickly becoming comparable with those on a 400m track. 12:51 is six seconds faster than Cheptegei’s 5,000m PB.
Opponents of Nike’s controversial shoe technology are sure to cry foul in respect to the Ugandan’s dramatic lowering of the record, but it’s important to keep in mind that Kipruto smashed the 10k mark in Adidas shoes. Cheptegei appeared to wear the Nike Vaporfly Next% on Sunday, and not the soon-to-be released Alphafly Next% that resembles Eliud Kipchoge’s shoe from his 1:59:40 marathon exhibition last October.
Cheptegei has started his 2020 season in the same fashion as he left off in 2019. In December, the 23-year-old set a short-lived 26:38 road 10k world record in Spain to cap a season that saw him win world titles in the 10,000m and in cross country.
