Retired swimmer Janet Evans held world records in the 400-, 800-, and 1,500-meter freestyle events until they were broken in 2006. At the end of Evans' career in 1996, she held 45 national titles—third only to Tracy Caulkins and Michael Phelps.
Recently, Evans attempted to make a comeback, but she did not qualify in the 2012 Olympic trials, thus she will not be going to London this year.
