Allyson Felix, who has more Olympic medals than any US track and field athlete in history, says she will retire after the 2022 season.

This season isn't about the time on the clock, it's simply about joy," Felix said in an Instagram post on Wednesday. If you see me on the track this year I hope to share a moment, a memory and my appreciation with you."
