Allyson Felix has been an advocate for moms since giving birth to her first child in 2018. As an Olympic athlete preparing for her first child, Felix said in a New York Times op-ed that she fought to receive a contractual guarantee from her then-sponsor Nike that she wouldn’t be punished if she didn’t perform her best in the months surrounding her pregnancy.

The company, however, refused, leading to a public outcry. Nike later enforced a maternity policy that protected sponsored athletes’ pay during their pregnancy.
