The provided articles do not contain any information about Ruth Chepngetich. Instead, they focus on Kenyan marathon runner Albert Korir, the 2021 New York City Marathon champion, who has been banned for five years after testing positive for a performance-enhancing drug (EPO). Korir admitted to using the banned substance, resulting in a reduced suspension from the original six years. The articles also highlight concerns raised by the Athletics Integrity Unit (AIU) regarding the global anti-doping system, suggesting it is failing to keep pace with increasingly sophisticated methods used by athletes to evade detection. The AIU chair, David Howman, warns that the fight against doping has stalled, implying that more needs to be done to effectively combat doping in athletics.
