Mabel is one of the rising stars of British sprinting, specialising in the 100m and 60m. Aged 17, just two years after winning her first English Schools title in 2022, she announced herself on the senior circuit by winning bronze in the 60m at the 2024 British Indoor Championships. She also won the England U20 60m title that year and established herself as one of Britain's leading young sprinters.

Mabel's international breakthrough came at the 2025 European U20 Championships in Tampere, where she won silver in the 100m, securing her first individual international medal. She also helped Great Britain win silver in the 4x100m relay. In 2026, Mabel made the step into senior international competition, setting a new 100m personal best of 11.18 seconds to win bronze at the UK Athletics Championships before representing England at the Glasgow 2026 Commonwealth Games, where she reached the 100m semi-finals and finished fifth in the 4x100m relay. Mabel has also been named on the British Athletics Olympic Futures Programme and continues to develop under coach Denise Timmis at Lincoln Wellington. Alongside athletics, she studies Neuroscience at the University of Nottingham.
