Muhammad makes breaking the 400m hurdles world record look way too easy. It's a feat she's pulled twice: once at the 2019 USATF National Championships and then again, later that year, at the world championships. Muhammad will also be going into Tokyo as the defending Olympic champion, setting up for a showdown with Sydney McLaughlin, the 21-year-old who placed behind her in the world championships and has beaten her in Diamond League races in the past. Their showdown and Muhammad's unflappable dominance on the world stage is set to create a riveting race.
