A mile is a mile is a mile, proper? Properly, no — not when you’re in a pool.
A mile in swimming is just not all the time the identical distance as a mile strolling, operating, or biking (or every other manner of masking distance on the bottom).
Whereas a mile is equal to 1,609 meters or 1,760 yards, a “mile” swim race is usually 1,500 meters or 1,650 yards.
Right here’s why: Solely three international locations (the U.S., Myanmar, and Liberia) nonetheless use imperial items of measurement, together with the mile. In all places else, metric is the usual.
That features the Olympics, which has included a 1,500-meter swim race — a distance often known as the “metric mile” — since 1908.
For swimmers coaching or competing in a pool that’s measured in yards slightly than meters, a 1,650-yard distance — just below 1,509 meters — presents the closest approximation of that 1,500-meter distance.
How Many Laps Are in a “Mile” Swim?
First issues first: When calculating what number of laps are in a mile in swimming, it’s vital to know precisely what a lap is.
One size of a pool — that’s, swimming from one wall to the opposite — is taken into account one lap.
(You could have heard that one lap equals two lengths — up and again — however “laps” and “lengths” are really the identical factor.)
It is determined by the place you’re swimming. In open water, a mile is a mile. However in a pool, it will get slightly difficult, as a result of swimming pools differ in dimension:
- Olympic swimming pools are 50 meters lengthy.
- “Quick-course” swimming pools are 25 meters lengthy.
- Most school and highschool swimming swimming pools within the U.S. are 25 yards lengthy.
Use this desk to determine what number of laps (or lengths) you’d have to swim in every sort of pool as a way to full a “mile” swim race.
|Pool Dimension||Laps Per Mile|
|50-meter pool||1,500 meters = 30 laps|
|25-meter pool||1,500 meters = 60 laps|
|25-yard pool||1,650 yards = 66 laps|
Now, if you wish to swim a full mile in a pool — aka 1,609 meters or 1,760 yards — then add one other 2 lengths in a 50-meter pool, 4 extra lengths in a 25-meter pool, or 4½ further lengths in a 25-yard pool.
(It gained’t be precisely a mile, however you’ll be inside a couple of toes.)
Irrespective of the space you select to swim, you’ll get an important exercise and burn energy.
At a average effort, a 150-pound individual burns virtually 200 energy whereas swimming for half-hour.
In the event that they swim at a vigorous tempo, that very same individual will burn about 335 energy in half-hour.
