68 laps in a 25 yard pool? 68 x 25 yards x 3 = 5,100 feet. That’s 180 feet short of a mile (5,280 feet). So 70.4 laps would be a mile.
Is there something I am missing?
I have been swimming 5000 a day,is there any need to pick up the pace. It takes me about an hour and twenty five minutes , no stopping. Thank you. I will be 60 this year.
