Knight switched from Ireland to Great Britain in 2018. She did so as she felt that she could better progress her cycling career in the UK. At that time, Ireland had no prospects of entering a team for Olympics 2020 and they did not possess an indoor
Velodrome to train on. Knight became British champion when winning the
individual pursuit at the
2020 British National Track Championships. Knight was chosen to be part of the
Team GB's 26-strong cycling squad for the delayed
2020 Tokyo Olympics where she was joined by
Katie Archibald,
Elinor Barker,
Laura Kenny and
Neah Evans for the endurance races. The team won the silver medal in the
women's team pursuit event. She was part of the Great Britain squad which won gold in the
team pursuit at the
2024 UCI Track Cycling World Championships in
Ballerup, Denmark. Knight was part of the British
team pursuit line-up that won bronze at the
2025 UCI Track Cycling World Championships. She then finished in second position in the
individual pursuit, where she was beaten in the final by her international teammate
Anna Morris. At the
2026 European Championships in
Konya, Knight was part of the British
team pursuit quartet who set a new
world record en route to the gold medal. The team consisting of Knight, Archibald, Morris, and
Millie Couzens also set a new
world record of 4:02.808 in the final against Germany. She then set a second
world record in the championships during the
individual pursuit. Her time of 4:19.461 made her the first woman to complete the event in under 4:20 and broke the previous record of 4:23.624 set by Italian cyclist
Vittoria Bussi. She went on to defeat Dutch rider
Mischa Bredewold in the gold-medal race. ==Major results==
