RIO DE JANIERO — Any time an Olympian shatters a world record by such a large margin, questions are inevitably raised.
Hungary’s Katinka Hosszu lowered the women's 400-meter individual medley world record — with an astonishing 4:26.36 at the Rio Olympics, besting the previous record set under a cloud of suspicionin 2012 by China’s Ye Shiwen by more than two seconds.
Shiwen’s record raised eyebrows back in London largely because of her final 50 split; her time was faster than that of Ryan Lochte, who won gold in the men’s 400 IM the same night.
