Well your answer will depend on which pool you are swimming in.
First let me define a lap as one length of the pool, so to go down and back is 2 laps.
25 yard pool - 132 laps = 3300 yards = 1.875 miles
25 meter pool - 128 laps = 3200 meters = 1.989 miles
50 meter pool - 64 laps = 3200 meters = 1.989 miles
There you go. I know 1.875 is a bit off, but in competitive swimming 1650 yards is considered "the mile".
Each lap in a pool is 25 meters. There are 1600 meters in a mile. 25m x 20 laps = 500 meters. You would need to swim 64 laps to make a mile. Therefore 20 laps is 0.31 miles.
One lap is a quarter mile. This means that four laps equals one mile, which means that four miles equals sixteen laps. It is very easy to count how many miles different laps equal for - you just need to multiply the amount of miles by four and you get the amount of laps.
32 laps Or to be exact, 32 laps plus 9.34 more meters into the 33rd lap.
3/4 mile track. 3/4 mile X 2 laps = 1 and 1/2 miles 3/4 mile X 3 laps = 2 and 1/4 miles For 2 exact miles you need to walk 2 and 2/3 laps of the track. However, may I suggest just walking the 2 and 1/4 miles (3 laps) to keep life simple?
it depends on the length of the pool. if the pool is 25 meters, you have to swim 40 laps. For 50 meters, 20 laps. For 100 m, 10 laps. For 200 meters, 5 laps.
Since 1.5 miles equals 7920 feet, you would need to run just under eight laps !
I mile = 5280 feet. So 2.4 miles = 12672 feet. At 40 feet per lap you would need to swim 12672/40 = 316.8 laps, or nearly 317 laps.
Since 1921, the IAAF has stated that a marathon's distance is standardized at 42.195K or 26 miles and 385 yards. If you are using a standard 400M track, and running exclusively in lane 1, then you will need to complete 105.4875 laps in order to complete a marathon or essentially 105 and 1/2 laps. If you use an outer lane, then you will not need to run as many laps.
