Good article on Tsegay, and the writer (Hannah Borenstein ~ does an excellent job with Ethiopian athletes who are limited as far as English) intimates that it might've cost her sub-14:
"Having to navigate her way around lapped runners probably cost Tsegay a sub-14-minute finishing time, but she was nevertheless delighted to emerge with her first senior outdoor world record, crossing the line in 14:00.21."
Either way, this record is on borrowed time for multiple Women ~ Kipyegon, Tsegay and possibly Chebet. Haylom certainly down the road may get there, as may Welteji. It might be past Hassan/Gidey for now as they look to the Marathon. It was run with some wind. I don't think the heat was too much of an issue actually, and the pacing was really good (~rarely get to 3K). If it doesn't happen because of championship doubles/triples these women are looking to do certainly in 2026, someone is going to go all out and maybe 13:55 is possible.
