Nana Takagi, who with her younger sister Miho became the first pair of speed skating siblings to appear at three Olympic Winter Games, announced her retirement on Tuesday.

The 29-year-old captured two gold medals at the Pyeongchang Games in 2018, in the team pursuit and mass start. She suffered two falls at the Beijing Games in February, including one that cost Japan gold in the women's team pursuit final.

"I've decided to end my career as an athlete," Takagi said at a news conference in Tokyo.
