Allyson Felix one step closer to making history

U.S. sprinter Allyson Felix finished second in her heat and advanced to the semifinals of the women's 400m, putting her one step closer to reaching a record 10 Olympic gold medals.

If Felix wins the 400m, she would have the record for most gold medals of any female track and field athlete with 10. If she also wins the 4x400m relay, she would surpass legend Carl Lewis with the most track and field gold medals ever. The Tokyo Games are the fifth Olympics for the 35-year-old track star.
