Swimming Records That Will Be Tough To Beat

Swimming is among the most competitive sports in the world today.
Whether competing at the World Championships or the Olympic
Games, swimmers are continually improving the best times for
various events. New records are often set at these international
competitions, with just fractions of a second making the difference
in transferring the title from one phenomenal athlete to another. But
some records have remained in place for years or decades. Some
records seem nearly impossible to break. Part of the Unbreakable
Sports Records? series, Swimming Records That Will Be Tough to
Beat tells the stories of five swimming record holders whose
personal bests might just stand the test of time.
