Susan Halter is considering retiring from international competition after medalling at the South East Masters and Senior age group long course event in Crawley.
With no opposition in her category, the former Olympian, aged 87, won gold in both the 50m and 100 backstroke races.
Halter said: “I felt very tired after the first event and didn’t feel up to competing in the 200m the following day. Perhaps I should give up galas and just have a swim for pleasure in the local pool.”
