Ruth Chepngetich surpassed Ethiopian Tigst Assefa's previous women's marathon world record by nearly two minutes at the Chicago Marathon in 2024
Women's marathon world record-holder Ruth Chepngetich has been banned for three years after the Kenyan admitted to anti-doping rule violations.
Chepngetich was provisionally suspended in July following a positive test for Hydrochlorothiazide (HCTZ) - a banned diuretic used commonly as a masking agent - on 14 March.
Chepngetich's achievements which pre-date that sample - including her world record time of two hours, nine minutes and 56 seconds in Chicago in October 2024 - will still stand.
The Athletics Integrity Unit (AIU) had sought a four-year ban but the 31-year-old's punishment was reduced to three years because she admitted to the violations.
