Swimmers typically qualify for Olympic events by performing exceptionally well in a series of competitions leading up to the Olympics, including national and international trials. Each country sets its own qualification standards, often based on time trials where athletes must achieve specific time benchmarks that are predetermined by their national governing bodies. Moreover, the FINA (International Swimming Federation) establishes qualifying times for most events, ensuring a high level of competition. These rigorous standards help identify swimmers who are not only fit but also capable of competing at the Olympic level.
