[1] Yana Klochkova blasted the world record to become Ukraine's first ever Olympic gold medalist in swimming.

Her spectacular swim shattered the previous global standard of 4:34.79, set by China's Chen Yan from the 1997 Chinese City Games in Shanghai, and lopped three seconds off an old, drug-tainted 1980 Olympic record from former East Germany's Petra Schneider.

Storming from fifth at the halfway turn, Beatrice Câșlaru raced to bronze with a Romanian record of 4:37.18 on the rear of a dominant breaststroke leg.

[2] Germany's Nicole Hetzer finished fifth in 4:43.56, while Sandeno's teammate Maddy Crippen, swimming outside in lane eight, earned a sixth spot in 4:44.63.

[7] Canada's Joanne Malar (4:45.17) and Aussie favorite Jennifer Reilly (4:45.99) rounded out the historic finale.
