Starting to time my 1 mile swim

Uh...<br><br>
Not to question your capability but... Weren't you just celebrating being under 12 minutes for 400 yards? That would be like 54 minute mile pace. Either you had a breakthrough... Or you gotta check the math.

1 mile = 5,280 feet = 1,760 yards.<br><br>
1,760y / 25y = 70.4 lengths or 35.2 laps.<br><br>
Most folks round that up to 36 laps or 1,800 yards and call that a mile. I think of 9 laps as a 1/4.

Only confused swimmers.<br><br>
The confusion comes from the fact that 1 mile = 1609 meters. If you're swimming in a 25 <span style="text-decoration:underline;">meter</span> pool, 33 laps is 1650 meters and gets swum as a mile for the same reason that 1,800 yards gets swum as a mile in a 25 <span style="text-decoration:underline;">yard</span> pool - it's the first lap count to exceed the mile distance.<br><br>
So... 1650 <span style="text-decoration:underline;">meters</span> is thought of as a mile swim. Swimmers confused about the difference between yards and meters call 1650 <span style="text-decoration:underline;">yards</span> a mile. It's not.
