Two years after Ruth Chepngetich's astonishing Chicago run, a failed drug test has left athletics stuck with a record it can't bring itself to celebrate.
Kenya's marathon royalty is facing a reckoning. Ruth Chepngetich, one of East Africa's most celebrated distance runners, now carries a doping cloud over the greatest marathon ever run by a woman, and the whole sport is wincing.
It was two years ago today in Chicago that she clocked 2:09:56, slicing 1 minute 57 seconds off the world record. Her own personal best fell by a staggering five minutes. American broadcasters reached for the moon landing, with one shouting "Bring it on Neil Armstrong!" Others simply kept repeating the word "unbelievable." Asked afterwards about those who suspected she was doping, Chepngetich said only: "People must talk. I don't know."
Then came the twist nobody wanted. Five months after that Chicago run, she failed a doping test. Suddenly the awe turned to unease, and the word "unbelievable" took on a very different meaning. Athletics would love to wipe the mark from the books, but the sport finds itself largely powerless to do so.
The damage goes well beyond one athlete. Kenya and its East African neighbours have built a proud reputation on distance running, and every case like this lets sceptics question the clean athletes grinding through the same roads and trails. The challenge now is protecting the credibility of the next generation while the sport works out what to do with a record it can't celebrate and can't erase.
