Here is what Coburn said about Chepkoech's 8:44 last year.
“I think it’s important to look at history and look at what happened with Ruth [Jebet] and I do think a woman can run 8:45, but I don’t think a woman can run 8:45 when for a whole season she runs 9 minutes and then runs 8:45. I don’t think that’s really possible. I think 9 minutes is still the holy grail of women’s steeplechase and I think that’s a time — that right under 9 minutes athletes can run clean, so hopefully there’s enough of us to get near that."
When asked if she thought Chepkoech’s record was legitimate, Coburn said, “I shouldn’t comment because there is no proof to prove otherwise, but I think it’s important to look at trends and history of performances and where there’s big outliers we might need to pause.”
Should be a fun meet. Here is our preview.
