Although individual Olympic glory was mostly elusive, Felix played a key role on the United States women's relay teams, winning six additional Olympic gold medals: four consecutive medals at 4 × 400 meters (2008, 2012, 2016, and 2020), and two at 4 × 100 meters (2012 and 2016). The 2012 U.S. Olympic 4 x 100 meters team also set the current women's 4 × 100 meters world record. Felix is the first female track and field athlete to ever win seven Olympic gold medals, one from an individual event and six from team relays. With 11 total medals from five Olympic appearances, she is the most decorated woman in Olympic track and field history and the most decorated American track and field athlete in Olympic history. Felix is also the most decorated athlete, male or female, in World Athletics Championships history with 18 career medals, 7 from individual events and 11 from team relays.
