Each swimming event is broken up into rounds with the purpose of trimming the field of competitors (which can sometimes number upwards of 90+ for individual events) down to a final race of eight. Individual events at distances of 200m and shorter require three rounds: preliminary heats, semifinals, and a final. Each athlete participates in one of several preliminary heats in hopes of recording a top-16 time, thereby advancing to the semifinals.

From there, the eight fastest swimmers across both semifinal heats advance to the final. Individual events at distances of 400m or longer, along with all relay events, do not include a semifinal round. In these events, only the top eight swimmers or teams across the preliminary heats advance to the final. In the event of a tie for the final lane in a semifinal or final round, tied competitors swim an additional head-to-head race to determine who advances. This is also known as a “”swim off””. Olympic swimming competition days generally contain two sessions: one for only preliminary heats, and a second for semifinals and finals. The exceptions are the first day of competition, which lacks a semifinal/final session, and the last day, which does not contain a heats session.

  3. Who is the idiotic female color commentator? She said Ledecky is the GOAT, even over Michael Phelps. He has 23 golds, she has 5. Her “unbreakable” records are already blown away by the male record holder at every distance. She is the GOAT woman swimmer, but stop there. She would lose to the men every time.
