Track & Field Olympic trials in Eugene, Oregon.
The 35-year-old Felix made her Olympic debut in 2004 and said this will be her final Games.Expected to participate in the 400 meters in Tokyo, as well as the 4x400 meters relay team and potentially the mixed-gender 4x400 meters relay, Felix would tie Carl Lewis' record for the most Olympic medals by an American track and field athlete with a podium appearance.
Felix is also slated to compete in the 200 meters at the Olympic trials later this week but would not be able to run in both the 200 meters and the 400 meters in Tokyo due to the schedule.
