Beridze competed only in the men's 50 m freestyle at the 2000 Summer Olympics in Sydney. Despite finishing among the top 25 swimmers from the European Championships in Helsinki, Finland, he received a ticket from FINA, under a Universality program, in an entry time of 24.13. He challenged seven other swimmers in heat three, including two-time Olympians Howard Hinds of the Netherlands Antilles and Emin Guliyev of Azerbaijan. Racing on the outside lane, he faded down the stretch to pick up a third seed in 24.28, a small fraction outside his entry standard. Beridze failed to advance into the semifinals, as he placed fifty-fourth overall in the prelims.
