Bethany Firth

Firth swims in S14, the class for intellectual impairment, which returned to the Paralympics in 2012 after being removed following a cheating scandal at Sydney 2000. She won backstroke gold for Ireland at London 2012, then switched to Great Britain and won several more golds from Rio onwards, across backstroke, freestyle and medley. Her career is the class's best argument for strict eligibility testing and its place on the programme.
