On the sixth day of the Games, Nachaev swam his two individual events, with only 90 minutes in between.

Nachaev registered a time of 23.23 to lead the fifth heat again, since he had previously done before in Sydney four years earlier. Nachaev failed to reach the semifinals for his third and final Olympic stint, placing thirty-sixth in the preliminaries.
