Winning four golds and five medals, the USA’s Katie Ledecky completed a historic 200m, 400m and 800m freestyle hat-trick, breaking two world records in the process. Not far behind was Hungary’s Katinka Hosszú, who lived up to her nickname of the “Iron Lady” by negotiating a punishing schedule to pick up three golds and four medals in total, setting world and Olympic records in the two individual medleys.

London 2012 - Hannah Miley, who won silver at last year’s World Championships, was unable to reach the podium for Britain in the 400m individual medley.
