Ethiopian Ababel Yeshaneh broke the half marathon world record by 20 seconds, beating new marathon world-record holder Brigid Kosgei in the United Arab Emirates on Friday.
Nike-sponsored runners lowered the men’s and women’s marathon and half marathon records since September 2018, each appearing to race in versions of the apparel giant’s scrutinized Vaporfly shoes.
Yeshaneh, a 28-year-old who finished 14th in the 2016 Olympic 5000m, clocked 1:04:31 for 13.1 miles to better Kenyan Joyciline Jepkosgei‘s world record from 2017.
Kosgei, a 26-year-old Kenyan, also came in under the old world record but 18 seconds behind Yeshaneh.
Kosgei took 81 seconds off Paula Radcliffe‘s 16-year-old women’s marathon world record on Oct. 13, clocking 2:14:04 to win the Chicago Marathon.
Nike Vaporfly shoes, including the prototypes worn by Kenyan Eliud Kipchoge when he ran a sub-two-hour marathon, were deemed legal by World Athletics’ new shoe regulations last month, according to Nike.
