Allyson Felix will compete at her 4^th Olympics in Rio de Janeiro. Felix was attempting to win the 200-400 metre double, which has only been done previously by Valerie Brisco-Hooks (USA-1984), Michael Johnson (USA-1996), and Marie-José Pérec (FRA-1996), but she did not qualify in the 200, obviating that chance. Felix will likely also run relays for the United States, certainly in the 4×4 and possibly in the 4×100, most likely in a heat, giving her 3 possible chances at medals and gold medals. Here are the possible things she can achieve:

If She Wins One Medal in Rio, Allyson Felix Will …

• Win her 7^th Olympic medal, moving her ahead of Jackie Joyner-Kersee among @TeamUSA women. With 6 medals, Felix and Joyner-Kersee currently have the most medals of any American women in track & field athletics.
• Move into a tie for 2^nd among all women, with 7 Olympic medals in track & field athletics. The current record is 9 by Merlene Ottey (JAM), with 3 women having won 7 medals – Irena Szewinska-Kirszenstein (POL), Shirley Strickland-de la Hunty (AUS), and Veronica Campbell-Brown (VCB) (JAM). Of note, VCB will compete at Rio in the 200 metres and likely the 4×100 relay, and could extend her own mark.
• Move into a tie for 5^th among all US women in any sport, with 7 Olympic medals. Three US swimmers have won 12 Olympic medals – Dara Torres, Jenny Thompson, and Natalie Coughlin; while Shirley Babashoff stands 4^th among US women with 8 Olympic swimming medals.

• Move into a tie for 3^rd among all track & field athletes, with 9 medals, trailing only Paavo Nurmi (FIN) with 12, and Carl Lewis (USA) with 10.

• Move into a tie for 5^th among all Olympic track & field athletes, with 5 gold medals. Felix would trail Paavo Nurmi (FIN) and Carl Lewis (USA), with 9; Ray Ewry (USA), with 8 (10, including 1906); and Usain Bolt (JAM), with 6, although he may extend that mark in Rio.

• Move into a tie for 3^rd among US female Olympians, in any sport, with 5 gold medals. The @TeamUSA record is held by Jenny Thompson (SWI), with 8, while Amy Van Dyken (SWI) has won 6, and Bonnie Blair (SSK) has won 5, with Blair winning hers at the Winter Olympics.

Note that Shelly-Ann Fraser-Pryce (JAM) would also equal this mark if she wins the 100 metres in Rio.
