Here’s what to watch at the world championships on Friday.

It’s Sydney McLaughlin vs. Dalilah Muhammad vs. the clock this evening.

Michael Norman, 24, is arguably one of the most talented sprinters in the history of this distance, but doesn’t have any individual Olympic or world Championship medals to show for it. His personal best in the 400 of 43.45 seconds is tied for the fourth-fastest time ever, but Norman hasn’t been able to put the pieces together at major meets as a professional. This season, Norman has looked his best since running 43.45 in 2019, delivering multiple sub-44-second performances. He ran away from the field at the U.S. championships, winning in 43.56 seconds. If healthy, Norman should be the first American world champion in the 400 since LaShawn Merritt in 2013.

This event should be a race between McLaughlin and the clock. McLaughlin easily broke her world record at the U.S. championships, running a mind-boggling 51.41 seconds that would have qualified her for the regular 400 final. The world championships should not be as easy, with fellow American Muhammad, the 2019 world champion, and Femke Bol of the Netherlands both in the field, but they will most likely push McLaughlin to run even faster.
