How the Swim Pace Calculator works
Pace per 100 m = total time ÷ distance × 100. Projected times assume you hold the same pace, which gets harder over longer distances. Example: with Distance 1,500 m, and Time 28 min, the result is Pace per 100 m = 1:52; Time for 400 m = 7:28; Time for 1,000 m = 18:40.
