Fitness Pace Chart yada baska bir deyisle cevap anahtari http://www.usms.org/fitness/pacechart.php
The following chart is a great reference tool for any swimmer. The chart provides general paces in minutes and seconds for set distances from 100 yards (or meters) to a one-hour swim. To use the chart, select a shorter distance (such as 100 yards or meters) and time yourself in a moderately paced swim. Record your time, and use this as a base for swims of longer distances. ‎- vikramthevampire
