Smith was at the pinnacle of sprinting for British women and a member of the national swim team for a decade. She had a busy programme at the 2012 Summer Olympics where she competed for the Great British team in the Women's 4 x 100 metre freestyle relay, finishing in 5th place in the final.
At the 2014 Commonwealth Games, she was part of the England 4 x 100 m freestyle team that won the silver and swam the heat for the silver medal winning 4 x 100 m medley team.[2][3]
Smith has now[when?] retired from competitive swimming but instead turned her attention to helping coach the next generation of swimmers through her swimming consultancy Swim Swift Elite[4] with her partner Joseph Roebuck.
