Miller-Uibo competed in athletics from a very young age and won five medals at the 2007 Central American and Caribbean Age Group Championships in Athletics in the under-14 category.

Bronze medals in relay races followed at the 2009 CARIFTA Games and the 2009 Pan American Junior Athletics Championships.

At 16 years old, she was the 400 m 2010 World junior champion and took the World youth title a year later.

She claimed the 400 m titles at the 2010 Central American and Caribbean Junior Championships and 2010 CARIFTA Games, as well as four medals with the Bahamas in the 4 × 100 metres relay and 4 × 400 metres relay.

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).
