Karsten Warholm shaved off his own world record by .76 of a second - a massive margin in a one-lap race - to hold off American Rai Benjamin to win in Tokyo in what would be remembered as one of the all-time great Olympic races.
Benjamin took silver in 46.17, also half a second inside Warholm's previous record of 46.70 while Brazilian Alison dos Santos took bronze in 46.72 as six of the first seven finishers set national or continental records.
Following his victory, Warholm spoke out to criticize the thick-soled shoes of Benjamin, despite also wearing spikes with a carbon plate that unquestionably improves performance.
"What I said was misunderstood in some way, because I had one comment about it after the race and it just blew up and that wasn't my plan at all," the 25-year-old said during an interview, also adding, "a little bit of help came from you know good shoes a good track and in good conditions. But I don't think that's fair to say that was what made me run fast because because I know that it's a lot of hard work and dedication behind it."
