🏊 Swim Pace Calculator
Pace per 100m and 100 yards from any swim
About this calculator
Swimmers measure effort in pace per 100 metres (or per 100 yards), the same way runners think in minutes per kilometre. This calculator converts any swim distance and time into that standard pace, so you can compare workouts, set interval targets, and track progress across the season.
Tip: Your easy pace and your threshold pace are usually 15 to 20 seconds per 100m apart. If they are closer than that, your easy days are too hard.
