Shaunae Miller-Uibo’s Sprinting Career
Miller-Uibo progressed from youth championships to senior international competition, winning major titles across the 200m and 400m. Her career includes Olympic victories, world titles, national records and Diamond League success.
Youth and Junior Championships
Miller-Uibo first gained international recognition at the 2007 Central American and Caribbean Age Group Championships, where she won five medals. In 2008, she won medals at both the CARIFTA Games and at the Pan American Junior Athletics Championships. In 2010, as a 16 year old, she won the World U20 Championships 400m in Moncton, becoming the first Bahamian woman to win the event.
The following year, she defended her 400m title at the World U20 Championships and also became World U18 Champion in the 400m with a time of 51.84. At the 2012 Olympics in London, Miller-Uibo was eliminated in the first round of the 400m. That same year, she turned professional and qualified for the 200m final of the World Championships in Moscow, where she finished fourth.
First World Medals and Olympic Gold
In 2014, Miller-Uibo won bronze in the 400 meters at the World Indoor Championships. She earned her first major medal at the senior level—in a global-scale competition—in 2015 at the World Athletics Championships in Beijing, where she won silver in the 400 meters. It was Miller-Uibo’s first individual major global senior final, and she placed second behind Allyson Felix. In August 2016 at the Olympics in Rio, Miller-Uibo finished first in the 400m final. She set a personal best of 49.44, and finished just 0.07 seconds ahead of Felix. It was her first Olympic gold medal. Her win in 2016 established her in the world’s best 400m field. She is the third fastest woman of all time in the event.
Diamond League Titles and National Records
Seasons following her historic 2016 performances further established Miller-Uibo’s talent. In 2017, at the World Championships in London, Miller-Uibo won the 200m bronze and 400m silver and set the Bahamas’ national records in both events. She also earned Diamond League titles in both events and became the first Bahamian to win the double in the same season. In 2018, Miller-Uibo won the 200m gold at the Commonwealth Games with a time of 22.09.
Later that same year, she successfully defended her Diamond League title in the 200 meters. At the 2019 World Championships in Doha, Miller-Uibo improved upon her 2017 performance in the 400 meters, setting a new Bahamian national record of 48.37 seconds; however, she finished in second place behind Salwa Eid Naser. Earlier that season, at the Diamond League meeting in Zurich, she had also set a Bahamian national record in the 200 meters, clocking 21.74 seconds.
Olympic Defence and World Titles
She finished eighth in the 200m final before defending her Olympic 400m title.
On 6 August, she won the 400m in 48.36 seconds, setting another Bahamian national record. Marileidy Paulino took silver, while Allyson Felix finished third.
The victory made Miller-Uibo one of the few women to win consecutive Olympic 400m titles.
Her success continued in 2022.
At the World Indoor Championships in Belgrade, she won gold in the 400m with a time of 50.31 seconds.
Later that year, Miller-Uibo claimed her first outdoor World Championships title in Eugene, Oregon.
She won the 400m final in 49.11 seconds, finishing ahead of Marileidy Paulino and Sada Williams.
The victory completed her collection of major senior 400m titles across the Olympic Games, World Indoor Championships and outdoor World Championships.
