Five-time Olympian Allyson Felix and world champion Noah Lyles cruised to the semifinals of the women's 400-meter and men's 200-meter, respectively.
Felix, competing in her fifth and final Olympic appearance, moved one step closer to becoming the winningest women's track and field athlete of all time, winning her heat in 50.84 seconds.
"The meaning and motivation is different this time," Felix said when asked if her goals have changed. "But I don't want to limit myself. I'm still going to go out and give everything I have."
