The most decorated American Olympian in athletics, Felix won her only solo gold in the 200m at London in 2012, but also topped the 4x400m relay podium at every Games between 2008 and the delayed 2020 Tokyo Games.
She also won 4x100m relay titles in 2012 and 2016, and took 200m silver in 2004 and 2008, along with 400m silver and bronze in Rio and Tokyo respectively.
The LA native also won a record 20 medals at the World Championships, the most for any woman or man, including 14 titles.
Felix, who also has a daughter born in 2018, attended the 2024 Paris Olympics as a spectator and said she experienced “mixed emotions”.
“There were moments where I was like, ‘Oh, this is so great. It’s so exciting to be in the stands and on the other side,'” Felix told Time magazine, external.
“And then there were moments where I was, ‘You know, I miss this feeling’.”
Felix, a member of the athletes commission for the 2028 LA Olympic organising committee, said she is realistic about her comeback.
“I know, at 40, I am not at my peak. I have no illusions about that,” she added. “I’m very clear in what it is and what I want to see. And so I hope it’s seen that way.
“When I was competing, you just heard this roar for host-country athletes at the Olympics. I would love to experience that.
“I would probably be upset at myself if I just didn’t give it a try. However it turns out, I’ll still be there with my kids, hanging out and cheering everybody on.”
