Allyson Felix used her legs to become the most decorated track athlete in American history, with more world titles than Usain Bolt and Carl Lewis. Though it wasn’t until her journey into motherhood that she found and used her voice.

In this episode, host Aarti Shahani talks with Felix about her metamorphosis – from quiet superstar to unexpected activist. The daughter of a pastor and a teacher, she discusses her early years, when she avoided politics (and also happiness!). We dissect just how she found herself in the center of a massive battle over maternal rights … and why exactly she took on her corporate sponsor, the biggest name in footwear: Nike.
