Rio Olympic marathon winner Jemima Sumgong tested positive for EPO, track and field’s international governing body (IAAF) said Thursday.
Sumgong, 32, became the first Kenyan woman to win the Olympic marathon in Rio. She also won the London Marathon last April and was set to defend that title later this month.
Sumgong is the second star Kenyan women’s marathoner to test positive for EPO.
Rita Jeptoo, a former Sumgong training partner, was stripped of Boston and Chicago Marathon titles for testing positive for EPO in 2014 and is banned until October 2018.
