Pemble was born in Lancashire, England with cerebral palsy affecting her right side.[1] Her parents thought it would be good for her to take up a sport to help with her balance and coordination.[2] She moved to Victoria, British Columbia at age 9 with her parents.[3] She twisted her knee after an early skiing lesson in France, but took up para-skiing again after moving to Canada.[1]
Pemble graduated from the Canadian Sports School-Victoria.[4]
At the 2015 Canada Winter Games, Pemble won the women’s Giant Slalom Para female race.[5] She also won a silver medal in slalom para alpine skiing at the Games.[6]
When she was 14, the Canadian Sport Institute Pacific's Podium Search program identified Pemble for para-cycling. She competed at the provincial level and used the sport as cross-training for skiing. She was coached by Kurt Innes, who later coached her upon her return to the sport in 2020 after a five-year break from the sport.[1]
She made her world debut in para-cycling competing at the 2022 UCI Para-cycling Track World Championships, at which she won a gold medal in omnium[13] and scratch race.[14][15] She set a para-cycling world record in the non-medaled 200-metre sprint in 2022.[16][17] She also placed third in the 500m time trial and fourth in the four-kilometre individual pursuit.[1]
Pemble competed at the 2023 Parapan American Games in Santiago, Chile. She won the gold medal in the women's 3,000-metre C1-3 individual pursuit.[19] She finished fourth in the women's individual road race C1–3[20] and seventh in the women's individual road time trial C1–5.[21]
She won a silver medal in the women’s C3 500m time trial and a bronze medal in the women's C3 omnium at the 2024 UCI Para Cycling Track World Championships.[22] Also at the 2024 UCI Para Cycling Championships, Pemble placed 5th in the Individual Pursuit and 6th in the Scratch Race.[23]
