[5][6][2][7] On July 30, 1964, at only 13, Caretto set her first two world records at the AAU National Championships at California's Foothill College in Palo Alto.

Meyer, who also set world records in the 200 and 400-meter swims, dominated the trial's distance events.

[9][11] Later in October, after travelling to the '68 Olympics in Mexico City as a 17-year-old, Caretto placed fifth in the final of the women's 800-meter freestyle.

Affected by altitude, fatigue, and recent illness, Caretto was 30 seconds slower than her Trials time.

She taught physical education to students with motor-skill or learning disabilities in Garden Grove Unified School District in California and married Sam Brown, her second husband.
