“This season I’m running for women. I’m running for a better future for my daughter. I’m running for you,” Felix wrote. “More to come on that, so stay tuned, but I’ll be sharing a series of announcements that I’m hoping will make the world better for women.”

“I feel completely fulfilled to have run that last race. There’s nothing I felt I left undone, you know? I feel confident walking away from the Olympics,” said the star, who is the oldest American woman to ever win a track and field gold medal.

“I’m so excited now through Saysh to continue to have a voice and hopefully continue to have an impact for women. I’m really excited for the next chapter,” she said in August 2021. “I hope I’ve been a source of inspiration, but more so for things off of the track. Obviously, it’s our profession, it’s what we love to do. But I think so many of these athletes are capable of also having a lot of impact in really meaningful ways outside of the sport as well.”
