 Former Dalhousie University student and national record holder Kiera Aitken participated on behalf of Bermuda for her second Olympic appearance after the 2004 Summer Olympics in Athens. Aitken participated in the August 10 preliminaries for the 100 meters women's backstroke, where she was placed in Heat 1 with Paraguay's Maria Virginia Baez and Panama's Christie Marie Bodden Baca. With a time of 1: 02.62, Aitken ranked first in her heat, defeating Baez by almost three seconds. However, her overall ranking placed her thirty-third out of forty-nine swimmers between Alana Dillette of the Bahamas (32nd) and Hiu Wai Sherry Tsai of Hong Kong (34th). Aitken was 3.62 seconds slower than Kirsty Coventry of Zimbabwe, who set an Olympic record during the preliminary round with a time of 59.00 seconds. Aitken did not make the time necessary to progress to the next round.
