Remember Olympic Swimmer Katie Ledecky? She's still breaking records

Katie Ledecky has resumed her world dominance over the freestyle at the World Championships in Budapest, Hungary. Ledecky, who became a breakout star at the Rio Olympics, made a mockery of the field in the 1,500-meter freestyle heats, an event in which she already held the world record. On Monday, Ledecky swam 15:47.54 in the 1,500 beating the second-place finisher by 17 seconds and the last-place swimmer by 97 seconds.
