University of Bath-based swimmers Siobhan-Marie O’Connor and Chris Walker-Hebborn set two British records apiece on day two of the FINA World Short Course Championships in Doha.
O’Connor’s time of 57.98secs in the 100m individual medley heats eclipsed her own previous standard of 58.26 and was the second fastest qualifying time of the morning.
The 19-year-old had earlier teamed up with Walker-Hebborn, Adam Peaty and Fran Halsall to qualify fastest in the mixed 4x50m medley relay in another national best time of 1min 38.16.
And there was a further British record for Walker-Hebborn in the men’s 4x50m medley relay as he, Peaty, Adam Barrett and Ben Proud qualified for Thursday evening’s final in 1:33.87.
Walker-Hebborn – who, like O’Connor, trains at the British Gas National Centre Bath – missed out on a place in the 100m backstroke final on Wednesday.
The FINA World Short Course Championships continue until Sunday.
