Kenyan marathon runner Ronald Korir provisionally suspended over doping
The Athletics Integrity Unit provisionally suspended Kenyan runner Ronald Korir on Tuesday over suspected doping.
Korir, 35, is a marathon runner who finished fourth in Berlin in 2023 and Hamburg in 2024.
The suspension is provisional while his case is investigated, so it is not a final ruling.
Korir's 2023 Berlin time was 2:04:22, placing him among the leading marathon runners.
More than 140 Kenyan athletes have been suspended or banned by the unit since 2017, including women’s marathon world record holder Ruth Chepngetich.
The case adds to scrutiny of Kenya’s anti-doping policies, as Nairobi is due to host the 2029 world championships.
No further steps or timetable for Korir’s case were stated.
