Her marks of 48.36 (improved at the Tokyo Games) and 50.21 seconds place her respectively sixth and joint eighth on the world all-time list.^[2] She holds world bests over the 300 metres outdoors and indoors.

At 16 years old, she was the 400 m 2010 World junior champion and took the World youth title a year later. At 19, Miller-Uibo placed fourth in the 200 m at the 2013 World Championships, and then took her first senior medal (a bronze) at the 2014 World Indoor Championships competing at 400 m. She was the 2018 Commonwealth Games 200 m champion and won four Diamond League titles, having secured the 200 m/400 m double in 2017; she owns circuit records in both disciplines.

Miller-Uibo holds the world's fastest women's marks in straight races of 150 m and 200 m. Her personal best of 21.74 s for the 200 m is a Bahamian national record.

Sixteen-year-old Miller-Uibo became the first Bahamian to be 400 m champion at the 2010 World Junior Championships in Athletics and the youngest woman to ever win the event. She won the gold medal in a time of 52.52, denying Margaret Etim, who finished second in 53.05 (this was the slowest winning time in the history of the event).^[5]

In the following year, Miller-Uibo won the 2011 World Youth Championships in Athletics with a time of 51.84, becoming the first athlete ever to hold both the U20 and U18 championship 400 m titles concurrently.^[6] She returned to defend her 400 m title at the 2011 CARIFTA Games, but was disqualified in the final. She also failed in her defence at the 2012 World Junior Championships in Athletics, trailing in fourth. However, she won 200 m and 4 × 400 metres relay silver medals at the 2012 CARIFTA Games. In her last age category competition, she won three gold medals (200 m, 400 m, 4 × 100 metres relay) at the 2013 CARIFTA Games and was given the Austin Sealy Award as the best athlete of the tournament.

She made the 200 m final at the 2014 Commonwealth Games but ended the race in sixth.

The 2015 season marked her first impact at the Diamond League, as she won the 400 m at the top level Athletissima and Memorial Van Damme meets. Miller-Uibo won the silver medal in the 400 m at the 2015 World Championships that year. She also ran with the Bahamian women's 4 × 400 m relay team in the heats at that competition and set a Bahamian national record of 3:28.46 minutes.

That same year, Miller-Uibo became the first Bahamian ever to win a Diamond League title as she claimed both the 200 m and 400 m titles.

Having dominated the 200 m during 2018 and 2019 and clocking a world-leading time in the 400 m in 2018, Miller-Uibo won the 400 m silver medal at the 2019 World Championships in Athletics in Qatar, running the tenth fastest time in history, a national record of 48.37 seconds.^[15][16] The winner of the event, Salwa Eid Naser, was provisionally suspended by the Athletics Integrity Unit in June 2020 for missing four anti-doping tests in 12 months, the last of which was in January 2020.^[17]

On 13 February 2021, Miller-Uibo broke the NACAC indoor 400 m record with a time of 50.21 seconds, set at the New Balance Indoor Grand Prix in New York.^[1] On 4 April, she opened her outdoor season with a world-leading time of 22.03 s, her fastest ever 200 m opener, set at the Pure Athletics Spring Invitational in Clermont, Florida.^[18]
