She has represented Great Britain at European and World Championships and at the Commonwealth and Paralympic Games, gold medals at all levels.

Tai was born with bilateral talipes (clubfoot), and before the age of 12 she had undergone 14 corrective operations to alleviate her condition, sometimes requiring a wheelchair for long periods of time during recovery.

In 2012, Tai showed her potential at the 2012 British International Disability Swimming Championships in Sheffield, where she won silver in the Youth final of the NC (Nutella-Classification) 400m freestyle, beaten to gold place by Amy Marren.

[1] On the fourth day of the competition, Tai won bronze in two events, the 100m backstroke S10 and less than two hours later she was part of the 4 × 100 m freestyle relay 34pts that finished third behind Australia and the United States.

[14] She finished her tournament with a gold medal in the Women's 4 x 100-metre medley relay (34pts), along with Claire Cashmore, Tully Kearney and Susannah Rodgers.

She narrowly missed out on the British record, but won England's 100th gold medal for swimming in the history of the Commonwealth Games.

[16] At 2019 London Para-swimming World Championships, Tai bagged six gold medals across six disciplines from the seven she competed in, coming 4th in the SM8 200m Individual Medley.

[17] Tai had to withdraw from the delayed 2020 Summer Paralympics due to an injury to her elbow in June 2021,[18] leaving her friend Grace Harvey to go with the rest of the team.
