So this actually happened — Alison dos Santos ran 45.80 seconds in Zurich tonight at the Diamond League meeting, and that's a new world record.
Karsten Warholm's mark of
45.94 had been standing since 2021, and honestly nobody was really expecting it to go tonight. Warholm was right there in the race, finished second, just had to watch dos Santos come off the last hurdle and pull away.The Brazilian is 26, unbeaten all season, but his personal best before tonight was
46.29 — set four years ago. He knocked nearly half a second off that in one run, which is a lot for this event.BBC Sport says the evening isn't over either — there are potential 800m world records on the table and Mondo Duplantis might be pushed in the pole vault.
