[1] Another medley double happened for the sixth straight time, as Hungary's Katinka Hosszú pulled away from the field to collect her third individual Olympic gold at these Games.

Leading from the start, she threw down a gold-medal time in 2:06.58 to establish a new Olympic record, and to hold off a charging Great Britain's Siobhan-Marie O'Connor by three tenths of a second.

[4][5] Meanwhile, U.S. swimmer Maya DiRado added a bronze to her runner-up prize from the 400 m individual medley three days earlier with a time of 2:08.79, edging out her teammate Melanie Margalis (2:09.21) to fourth by almost half a second.

[6][7] Australia's Alicia Coutts, silver medalist from London 2012, culminated her Olympic career with a fifth-place time in 2:10.88, and was shortly followed in sixth by Canadian swimmer Sydney Pickrem (2:11.22).

[7] Hosszú also posted an Olympic record in 2:07.45 to lead all swimmers on the morning prelims, clipping 0.12 seconds off the previous mark set by Ye Shiwen in London four years earlier.
