If you’ve ever attended a swim meet, you’ve probably heard a mix of unfamiliar terms—prelims, finals, time trials, heats, local meets, states, nationals—it can feel like learning a whole new language. Even Olympic broadcasters use cheat sheets to keep up with and understand swim meet terminology!

Whether you’re a swimmer, coach, parent, or meet organizer, you must understand swim meet terminology to make a huge difference in operating a smooth, successful swim meet. Let’s break them down so you can navigate swim meets with confidence.

Swim Meet Terminology Explained

Prelims and Finals

Many swim meets use a prelims-finals format. Here’s how it works:

  • Prelims (Preliminary Rounds): Swimmers compete in the morning or early afternoon, racing for a spot in the finals.
  • Finals: The fastest swimmers from prelims race again in the evening to determine final placements.

Some meets have two levels of finals:

  • A Final (Championship Final): The top 8 swimmers from prelims compete for the highest placements.
  • B Final (Consolation Final): The next fastest group (usually places 9-16) races for rankings just outside the top 8.

This format makes meets more exciting, giving swimmers a chance to improve their times and race head-to-head with the best.

Time Trials

Ever wish you could redo a race? That’s where time trials come in. These special races happen outside the main competition to give swimmers a shot at improving their times or qualifying for bigger meets. Unlike regular events, swimmers in time trials don’t compete against others—they just race against the clock.

Heats

Because there are only so many lanes in a pool, races are broken up into heats—smaller groups of swimmers competing in the same event.

  • Seeding from Slow to Fast: In most meets, the slowest swimmers go first, and the fastest swimmers race in the final heats.
  • Circle Seeding: Used in prelims-finals meets, this format spreads the fastest swimmers across the last few heats, making for a more competitive race in the prelims.

Even though swimmers race in different heats, their final placement in an event is determined by time—so someone in an early heat can still win the whole event!

Local, State, and National Meets

Once you understand swim meet terminology you will se that swim meets come in different levels, from small local events to major national competitions:

  • Local Meets: These are open to all swimmers and are great for gaining experience.
  • State Championships (States): Swimmers must qualify with fast enough times to compete.
  • National Meets (Nationals): The best of the best—only the fastest swimmers qualify to compete at this level.

For elite swimmers, nationals can be a stepping stone to international competitions like the Olympics.

What’s an Event? What’s a Course?

  • Event: The word “event” can mean two things—it can refer to the entire swim meet or a specific race within a meet. For example, the “200-meter freestyle” is an event, just as “Nationals” is an event.
  • Course: This refers to the pool size used for competition. There are three main types:
    • Short Course Yards (SCY): 25-yard pools (common in U.S. high school and college meets).
    • Short Course Meters (SCM): 25-meter pools (used in international and club competitions).
    • Long Course Meters (LCM): 50-meter pools (used for the Olympics and World Championships).

How Are Swim Times Recorded?

A swimmer’s performance is all about time—measured down to hundredths of a second. Here’s how officials make sure everything is accurate:

  • Hand Timing: Officials use stopwatches (not as accurate, but a good backup).
  • Automatic Timing Systems: Touchpads at the finish register exact times.
  • Reaction Time Sensors: Used to measure how fast swimmers leave the starting block in a race or relay exchange.

Final Thoughts on Operating Swim Meets

Swim meets can be fast-paced and intense, but once you understand swim meet terminology, everything starts to make sense. Whether you’re running a meet, coaching a team, or cheering from the stands, knowing how prelims, finals, heats, and different levels of competition work makes the experience way more enjoyable.

By learning the ins and outs of operating swim meets, you’ll feel more confident, and if you’re in charge of organizing one, you’ll ensure everything runs smoothly from start to finish.
