At the 2008 Summer Olympics in Beijing, Kazikova qualified for the second time in the women's 50 m freestyle. She cleared a FINA B-standard entry time of 25.93 seconds from the Czech Winter Championships in Prague. She challenged seven other swimmers in the eighth heat, including Bahamas' Arianna Vanderpool-Wallace, Jamaica's Natasha Moodie. Kazikova cruised to third place by 0.14 of a second behind Vanderpool-Wallace, with a time of 25.54 seconds. Kazikova, however, failed to advance into the semifinals, as she placed twenty-ninth out of 92 swimmers in the preliminaries.
