Caroline Dubois was once better known as Colin. Not through choice, but as a nine-year-old boxing fanatic unable to fight in the gym without disguising herself as a boy.

A decade on, the Olympian is instantly recognisable as she struts to the ring to the tune of a new alias, “Sweet Caroline”. Ahead of her professional debut, she feared she would not be able to cope with the pressure of that ring walk, with thousands of eyes on a fighter frequently being described as the most promising prospect in women’s boxing.

But she learned to relish the attention, just as she has been enjoying every step of her journey since ditching the amateur scene on the back of Tokyo 2020. She can now see her victory over Vaida Masiokaite in a different light.

Dubois started boxing at the age of nine. While there were all-girl amateur boxing clubs in her city, her father wanted her to practice at a top-flight club where her older brother Daniel had trained. For her first few months at Repton Amateur Boxing Club, Dubois pretended to be a boy named Colin.

At the 2017 European Junior Championships, Dubois beat Nune Asatrian by a unanimous points decision in the final to take the title. The following year, she had a win at the English National Youth Championships (60 kg) with a unanimous points decision against Ellis Hopkins.

She became England’s first World Youth Champion by recording a win over Asatrian by unanimous points decision in August 2018, having previously won in her semi-final by unanimous decision against Rebeca Santos. At the Girls’ lightweight competition at the 2018 Summer Youth Olympics, Dubois won the gold medal by beating Porntip Buapa in the final.

The 2019 European Youth Championships 2019 saw Dubois achieve a unanimous points win over Amina Abramova in their semi-final before winning the title with a split decision against Asatrian in the final. Her next fight was the final of the England Boxing National Youth Championships, which she won by unanimous decision against Wenessa Orczwk. As of February 2020, Dubois was unbeaten and expressed an ambition to turn professional.
Dubois won the SportsAid One-to-Watch award for 2018, having been chosen from around 1,000 candidates across 60 sports nominated by their sport’s governing bodies. She had previously been on the shortlist of ten for the 2017 award and was named BBC Young Sports Personality of the Year in 2019.

She qualified for the 2020 Summer Olympics at the 2020 European Boxing Olympic Qualification Tournament. She took the silver medal after losing to Kellie Harrington on a split decision in the final. At the time of turning pro, Dubois had an amateur record of 37 wins and three losses.
