Shaunae Miller-Uibo broke the 400 meters national record in the IAAF Diamond League in Monaco. She ran the race in a blistering time of 48.97 seconds lowering the national record of 49.07s set by Tonique Williams in Berlin, Germany back in September 2004. Miller-Uibo is now the only Bahamian woman to run under 49 seconds in this event and became just the 10th woman to ever run under the 49 second barrier. Miller-Uibo’s personal best was previously 49.44 that she set at the 2016 Rio Olympics in Brazil where she won gold in dramatic fashion over USA’s Allyson Felix. With this time, Miller-Uibo set a meet record and solely has the world leading time. France’s Marie-Jose Perec previously held the meet record, a feat she did back in August 1996. This is the fourth national record that she adds her name next to. The other three are the 150m straight, 200m and the 200m straight.
