Paris 2024 is the second Olympic games in history to feature the 4x400-meter mixed relay. Poland won the inaugural competition in 2021 and set the first Olympic Record which was 3:09:87. That record didn't even last four full years as Team USA smashed it during a preliminary heat on Friday.
Vernon Norwood, Shamier Little, Bryce Deadmon and Kaylyn Brown set the new Olympic record as well as a new world record of 3:07.41 and no one else in their heat was close. Brown ran the anchor leg of the race and it's unclear if any other country had runners close enough to still see her when she crossed the finish line. It was downright Ledecky-esque.
