How Many Laps Is 800m Swim?

By Sarah Miller · March 14, 2043

The 800m swim consists of 16 lengths or 8 laps in a standard 50-meter Olympic-sized pool. In a 25-meter short course pool, it requires 32 lengths or 16 laps. This distance is commonly swum in competitive events and fitness training.

Understanding the 800m Swim Distance

The 800-meter swim is a middle-distance event popular in both long course (50m) and short course (25m) swimming competitions. It tests endurance, pacing, and technique, making it a benchmark for intermediate to advanced swimmers.

What Is a Lap vs. a Length?

A common source of confusion is the difference between a lap and a length. In competitive swimming:

Length: One way across the pool (e.g., 50 meters in a long course pool).
Lap: Down and back (i.e., two lengths or 100 meters in a 50m pool).

Thus, 800 meters equals 16 lengths or 8 laps in a 50m pool.

Swimming 800m in Different Pool Sizes

The number of laps required to complete 800 meters depends on the pool length. Most competitive pools are either 25 meters (short course) or 50 meters (long course). Some facilities use 25-yard pools, especially in the United States.

Pool Type	Pool Length	Total Lengths	Total Laps (Down & Back)	Distance per Lap
Olympic / Long Course	50 meters	16	8	100 meters
Short Course (SCM)	25 meters	32	16	50 meters
Short Course Yards (SCY)	25 yards (~22.86 meters)	35.2 (approx 35–36)	17.6 (approx 18)	50 yards (~45.72 meters)

The table above shows how pool size directly impacts the number of lengths and laps needed to complete 800 meters. Swimmers must adjust their pacing strategy based on turn frequency—more turns in short course pools can affect overall time and energy expenditure.

Training and Racing the 800m Swim

The 800m swim is a key event for developing aerobic capacity and race strategy. It's often used as a fitness test and is part of freestyle events at national and international levels.

Key Training Tips for the 800m

Pace Consistency: Maintain even splits to avoid early burnout.
Turn Efficiency: In short course pools, streamline off every wall to maximize momentum.
Breathing Control: Use bilateral breathing to maintain balance and oxygen intake.
Interval Sets: Example: 8 x 100m at goal pace with 15 seconds rest.
Descending Efforts: Practice finishing strong with negative-split sets like 4 x 200m (each faster than the last).

Common Mistakes to Avoid

Starting too fast and fading in the final 200m.
Ignoring flip turns in short course, leading to wasted time.
Poor sighting in open water variations (if applicable).
Insufficient warm-up or cool-down for such a demanding distance.

Frequently Asked Questions About the 800m Swim

How many laps is 800m swim in a 50m pool?

In a 50-meter Olympic-sized pool, 800 meters equals 16 lengths or 8 laps (where one lap is down and back). This is the standard configuration used in the Olympics and World Championships.

Is the 800m swim an Olympic event?

Yes, the 800m freestyle is an Olympic event for women, while men compete in the 1500m freestyle. At the World Aquatics Championships, both men and women swim the 800m freestyle.

How long does it take to swim 800m?

Elite swimmers complete 800m in around 8 minutes (men) and 8:20–8:40 (women). Age-group or recreational swimmers typically take 12–20 minutes depending on fitness level and stroke efficiency.

Can I swim 800m in a 25-yard pool?

Yes. In a 25-yard pool, 800 meters is approximately 875 yards, requiring about 35 lengths or 17.5 laps. Since you can’t swim half a lap competitively, most programs round up to 36 lengths (900 yards) for simplicity.

What is a good 800m swim time for beginners?

A beginner swimmer may take 18–25 minutes to complete 800m using freestyle. A solid intermediate time is under 15 minutes, while sub-12 minutes indicates strong endurance and technique.
