Frederico Rosa, agent to numerous world champions, faces scrutiny as Kenyan athletes continue to test positive for banned substances, most recently women's marathon record holder Ruth Chepngetich.
Ruth Chepngetich's suspension has plunged Kenyan athletics into a crisis of confidence. Doping is no longer an individual problem but reflects widespread inadequacies and a lack of transparency within the sport's management system.
Ruth Chepngetich's provisional suspension for a banned substance raises questions not only about her reputation, but also about the legitimacy of other long-standing world records under suspicion of doping.
Ruth Chepngetich, the Kenyan runner who holds the women's world marathon record of 2 hours 9 minutes 57 seconds, has been provisionally suspended after a banned substance was found in a urine sample from 14/3/2025.
