Glenda Joy Stirling (married name Biddle, born 7 July 1952) is a former New Zealand swimmer who represented her country at the 1968 Summer Olympics and 1970 British Commonwealth Games.
Stirling was born in Auckland on 7 July 1952.[1] Her father was Ivor Gerald Stirling and her mother was Joyce Agnes Stirling (née Hunter), a daughter of politician Lorrie Hunter.[2] She married Jack Edward Biddle, and the couple went on to have five children.[3] Her brother, Ken, was a New Zealand rugby league international, as was her father.
Stirling competed in three events at the 1968 Summer Olympics, reaching the final and finishing eighth in the 100 m backstroke. She also competed in the 200 m backstroke and 4 × 100 m medlay relay, but did not progress beyond the heats.[1] At the 1970 British Commonwealth Games in Edinburgh, she competed in the same three events, finishing fourth in both the 100 m backstroke and 4 × 100 m medlay relay, and sixth in the 200 m backstroke.[4]
