How many laps in a 40 ft pool is a mile

How Many Laps In A Pool Is A Mile?

Whether you’re running, walking, biking, or even rollerskating, sorting out how long you need to go to reach the one-mile mark is a straightforward task: Just head 5,280 feet and you’ve done it. But for swimmers trying to sort out how many laps in a pool makes a mile, finding the answer is decidedly more complicated.

WHAT DO YOU MEAN BY “MILE?”

Outside the water, the distance denoted by the term “mile” doesn’t change. Everywhere you go on dry land, a mile is a mile: 5,280 feet, 1,760 yards, or 1,609 meters. In the pool, though—especially if you’re racing—things aren’t quite as cut and dry as they are on dry land.

Racers who complete the “mile” race in the pool are actually only swimming 1,500 meters, or 1,650 yards. This length, also known as the “metric mile,” has long been a standard of competitive swimming, first being included in the Olympics in 1908. However, in the United States, one of the few countries that still uses the imperial measurement system, a mile still refers to the longer distance of 1,609 meters. This means that, if you’re in the US and taking part in an event like a triathlon, this is the mile-length you’ll need to train for.

HOW MANY LAPS MAKES A MILE?

Once you know which iteration of the mile it is that you’re looking to swim, to know how many laps that equates to in the pool you’ll need to consider the length of the pool you’re swimming in. Here, again, it can get a little bit tricky. Many pools in the US, whether they’re at a high school, college, or the local gym, are 25 yards long. But if your go-to pool is an Olympic-size pool, it is 50 meters long, and if it’s what’s known as a “short-course” pool, each length that you swim will net you 25 meters. So, how many laps in those pools are in the two types of miles noted above? Let’s start with the metric mile (1,500 meters) that’s used for most indoor competitive swims:

  • If you’re swimming in an Olympic pool (50 meters long), a metric mile is equal to 30 laps.
  • If you’re swimming in a short-course pool (25 meters long) a metric mile is equal to 60 laps.
  • If you’re swimming in a 25-yard pool, a metric mile is 66 laps.

On the other hand, if you’re looking to swim a “true” mile (5,280 feet or 1609 meters), the number of laps it takes are as follows:

  • If you’re swimming in an Olympic pool (50 meters long), a true mile is equal to 16.1 laps.
  • If you’re swimming in a short-course pool (25 meters long) a metric mile is equal to 32.2 laps.
  • If you’re swimming in a 25-yard pool, a metric mile is 35.2 laps.

As you can see, the true mile swim doesn’t divide neatly into exact laps or lengths of the pool. Nevertheless, these numbers should give you all you need to go into the pool informed and ready to hit your goals. 

The sport of swimming contains a lot of strange terms and jargon which some elite-level swimmers don’t even fully understand. One of the most confusing aspects is perhaps the mile swim. 

Although it may seem simple enough there is actually quite a bit of confusion regarding the mile swim as your typical swimming mile isn’t actually the same distance as say a mile running or cycling for example.

With the mile swim being a goal of many swimmers around the world, this has resulted in many left clueless on how many laps there really are in a mile swimming. (And how many they should swim to reach that “milestone”).

That said, in today’s article we’ll cover everything you need to know about the number of laps in a swimming mile as well as some additional information about the mile swim that might come in handy during your future swims.

Quick Answer- 

The number of laps you will need to swim to complete a true mile will depend on the length of your pool. In a 25-yard pool, 1 mile is 70.4 laps. In a 25-meter pool, 1 mile is 64.4 laps and in a 50-meter pool, 1 mile is 32.2 laps.

Similarly, the number of laps you will need to swim to complete a swimmer’s mile will also be dependent on pool length. In a 25 yard pool, you’ll have to swim 66 laps. In a 25 meter pool, you’ll have to swim 60 laps, and in a 50-meter pool, you’ll have to swim 30 laps.

Distance 25 Yard Pool 25 Meter Pool 50 meter Pool
Swimmer’s Mile (1650 Yards/ 1500 Meters) 66 Laps 60 Laps 30 Laps
Full Mile (1760 Yards/ 1610 Meters) 70.4 Laps 64.4 Laps 32.2 Laps

Perhaps the most confusing aspect about the mile swim is its distance. As mentioned earlier the “swimming mile” isn’t actually the same distance as your standard mile which is typically defined as 1760 yards or 1610 meters. 

In swimming there are 3 main mile distances typically used by different categories of swimmers, let’s have a quick look at them.

The Meet Mile: Most swimmers are probably familiar with the meet mile as this is the distance commonly used in all international swimming competitions that take place in a pool. 

In a yard competition pool, the mile is defined as 1650 yards which is actually 90 yards short of a real mile, and in a meter competition pool, the swimming mile is defined as 1500 meters, equating to roughly 1640 yards, once again short of an actual mile.

You can learn more about why this is the case here.

The Pool Training Mile: For training purposes, swimmers use either 1650 meters or 1650 yards to train for the mile event, both of which will provide subsequent fitness for the actual competition mile, defined as either 1500 meters or 1650 yards as we discussed just now.

The Open Water Mile: In open water swimming a mathematically-correct mile is used. Meaning 1760 yards or 1610 meters. If your goal is to train for a true mile for an open water event then you should divide 1760 yards by the length of your pool (if it is in yards) or if your pool is in meters you should divide 1610 meters by its length. 

With all that said, you may still be wondering so what is the distance of a mile swim? And the answer to that is- it depends. 

It depends on what your goal is- do you want to swim an actual mile? If so, train to complete 1760 yards or 1610 meters. On the other hand, if your goal is to swim a mile in a competitive swim meet, then train to complete 1650 yards or 1500 meters.

Laps Vs Lengths- Is There A Difference?

The next aspect that we need to cover in order to avoid confusion is the difference between laps and lengths- which if you are an experienced swimmer- you should know actually doesn’t have any difference at all.  

Many recreational or beginner swimmers seem to believe that a lap is defined as 2 lengths of a pool, meaning swimming both up and down, while a length is swimming from one side of the pool to the other. This is incorrect as I explain in my article here- “What Is A Lap In Swimming?”.

In order to avoid confusion, you need to understand that both a lap and a length are the same distance, meaning swimming from one end of the pool to the other. 

To explain this simply- the definition of a lap is a complete trip around a race track. In swimming, the pool is the race track, thus if you’ve swum from one end to the other then you have completed the track, meaning one lap or length. 

Still don’t believe me? Well, listen to what Natalie Coughlin, a 12-time Olympic medalist swimmer, has to say-

Your Pool Size Effects The Number Of Laps In A Mile Swimming.

Now that you understand what distance you are training for and that there aren’t actually any differences between a lap and a length, you need to understand the effect of your pool size on the number of laps you will have to swim.

To make things easier here are the 3 main pool lengths used by swimmers around the world, both for training and competition-

25 Yard Pool: This is the pool length typically used by swimmers in the U.S. during the short course season, which takes place primarily throughout the winter months. 25 Yard pools are typically used for high-school and college swimming meets while many recreational pools in the U.S. are also 25 yards in length. 

25 Meter Pool: Although only slightly longer than 25 yards, this is the pool length used by most other countries outside of the U.S for their short-course swimming meets. The 25-meter pool length is also used for international short-course swimming competitions around the world such as the World Short Course Swimming Championships which takes place every 2 years.

50 Meter Pool: This is the most common pool length used in international swimming competitions, including the Olympic Games. Almost all other swimming meets, including age-group competitions, take place in a 50-meter pool with many swimmers also training in this pool length throughout the year.

Unconventional Pool Sizes: Many swimmers may train in pools of varying lengths. This can include 20-yard, 30-yard, or 40 yard pools for example. These pools are suitable for training purposes but can’t be used for regulated swimming competitions. 

The effect of your pool length on the number of laps you have to swim: Naturally, the longer your pool is the fewer laps you will have to swim to complete the mile swim, while the shorter your pool is the more laps you’ll have to swim to complete the mile swim.

Laps In A Mile Swimming- The Swim Distance Charts.

Now that we have covered all of the aspects that you need to understand to avoid confusion when it comes to swimming a mile in a pool, we can get to how many laps are in a mile swimming. Below is everything you need to know in order to swim a mile depending on your goals and training purposes.

Number of laps in an actual mile (1760 yards/ 1610 meters):

  • 25 Yard Pool: 1760 yards is 70.4 laps.
  • 25 Meter Pool: 1610 meters is 64.4 laps.
  • 50 Meter Pool: 1610 meters is 32.2 laps.
Pool Length Actual Mile Distance (1760 Yards Or 1610 Meters)
25 Yards 70.4 Laps 
25 Meters 64.4 Laps
50 Meters 32.2 Laps

Number of laps in a swimming mile (1650 yards/ 1500 meters):

  • 25 Yard Pool: 1650 yards is 66 laps.
  • 25 Meter Pool: 1500 meters is 60 laps.
  • 50 Meter Pool: 1500 meters is 30 laps.
Pool Length Swimming Mile Distance (1650 Yards Or 1500 Meters)
25 Yards 66 Laps
25 Meters 60 Laps
50 Meters 30 Laps

For unconventional pool sizes, you’ll have to do a little bit of math to figure out how many laps you’ll have to swim in order to complete a mile. Luckily it isn’t all that hard.

You can use this formula to calculate how many laps you have to swim to complete a mile-

Numbers of yards/ meters in a swimmer’s mile/ actual mile ÷ the distance of the pool (in yards or meters).

Example: Say your pool measures 20 yards long and you would like to complete a full mile swim, then all you have to do is take 1760 yards and divide it by 20. That would equal a total of 88 laps that you would need to swim to complete a full mile.

How To Count Your Laps While Swimming A Mile.

Knowing how many laps you should swim to complete a mile swim is all good and well, but it doesn’t exactly help if you miscount your laps along the way since you’ll ultimately be cheating yourself and your swimming goals.

As an experienced competitive swimmer myself, I know how easy it is to miscount laps or completely lose track all together when doing longer distance swims (I probably do it at least once every training session, luckily I have good teammates around). 

For those training on your own, here are 2 useful methods for making sure you complete that full mile swim and reap all the rewards as well-

GPS Swim Watch: Probably the easiest and most accurate way to measure how many laps you have done is by using a GPS swim watch.

I have found the Garmin Swim 2 to by far be the most accurate swimming watch on the market. What’s great about this watch is that it can measure both open water and pool swimming and it comes in at a very affordable price compared to watches with similar capabilities.

You can check it out on Amazon by clicking here if you’d like.

Ray over at DC Rainmaker also did a really great review on the watch if you’d like to learn a bit more about the Garmin swim 2.

Wearable Lap Counter: Another effective and cheaper way of counting your laps, but one that requires a bit more brainpower is a simple device that you can wear on your finger known as a wearable lap counter. 

This is a low profile, low-tech device where you press a button each time you have completed a lap. It also has a timer built-in so that you can see how fast you are swimming your laps. You can check out this nice one on Amazon here.

How Long Does It Take To Swim A Mile? The Average Mile Swim Time.

You might be wondering what is the average time it takes to swim a mile? This will give you a good goal to aim for to make sure you are on track to swim some decent times in the pool. 

Anyway, a while back I did an article on the average mile swim time and analyzed the times of 425 swimmers from a wide spectrum of ages and experience levels who competed in a mile open water race to provide you with an average time to aim for. 

In short, the average time it took to complete a mile swim in open water was exactly 30 minutes and 0.02 second. Obviously, in a pool this time is going to be a bit faster as you will probably have a bit less waves, better vision, and also walls to push off from after each turn. So that time for a pool swim should probably be sitting around 25-27 minutes.

That said, these times might not apply to everyone. Here are some general guidelines to aim for when swimming a mile for time-

Beginners should take anywhere from 40 to 50 minutes to swim a mile, while intermediate swimmers will be able to swim a mile in 30 to 35 minutes, and advanced swimmers in 25 minutes or less. Elite level swimmers should be able to go under 20 minutes for the mile swim.

Swimmer Level Mile Swim Time
Beginner Swimmers > 40 Minutes
Intermediate Swimmers 30-35 Minutes
Advanced Swimmers 25 Minutes
Elite Swimmers < 20 Minutes.
