One of the fastest sprinters on Earth, Felix continues to blaze through the competition well into her 30s. The six-time Olympic Gold Medalist has dominated the past three Games, excelling in the 200m, the 4x100m relay, and the 4x400m relay. Felix and the U.S. relay team won the 4x400m gold medal at Beijing in 2008, London in 2012, and Rio De Janeiro in 2016.
Despite enduring several injuries over the last few years, Felix has been a consistent performer throughout the entirety of her career. Felix has at least one first-place finish in 11 of the last 12 international events she has participated in. In total, Felix has 24 gold medals to date.
