Swimming World Record Book Takes a Pounding at World Champs and After
During the FINA World Championships last month in Budapest, 11 swimming world records were taken down, in addition to numerous American records. And since then, several short course world records have also gone down during the first three stops of the FINA World Cup.
The Swimming World Record Book is officially up-to-date with all World and American records for both short course and long course.
Sarah Sjostrom has been the biggest world record-breaker over the past month, setting new global standards in two long course events and three in short course (although one of her SCM world records has since been broken). Other long course record-setters include Adam Peaty, Lilly King and Kylie Masse.
Check out all individual long course records below.
