Sweden's Sarah Sjostrom broke the women's 100m butterfly record on Sunday as Sun Yang and Katie Ledecky retained their 400m freestyle titles at the world championships. China's Sun, the reigning 400, 800 and 1500m world champion and record holder over the mile, clocked three minutes 42.58 seconds to win his final by more than a second as Britain's James Guy took silver. The Chinese giant is still nearly three seconds from Paul Biedermann's world record, set by the German in 2009 before neoprene suits were banned, and it remains his goal a year from the Rio de Janeiro Olympics.
