World record holder in the women's marathon, Ruth Chepng’etich, has been banned for three years after admitting to anti-doping rule violations, the Athletics Integrity Unit (AIU) announced on Thursday, October 23.
The Kenyan runner, who recently established the world record time of 2:09:56 in Chicago in October 2024, faces the ban despite seeing her historic performances before the positive test documented in the ruling.
