Swim Pace Calculator
Calculate your swim pace per 100 m or 100 yd from distance and time — and predict times for other swim distances.
For general information only — not medical advice. Results are estimates; talk to a doctor or qualified health professional about your own health.
How to use
- 1Enter the distance you swam and your time.
- 2Choose metres or yards.
How it's calculated
Pace per 100 = time ÷ distance × 100. Predictions use the same pace (swimming slows less with distance than running).
Frequently asked questions
What's a good swim pace?
Many adult fitness swimmers hold 2:00–2:30 per 100 m; competitive age-group triathletes are often under 1:45.
Metres vs yards?
100 yards is 91.44 metres, so the same effort is about 9% faster per 100 in yards.
How do I improve swim pace?
Technique drills (body position, catch) usually help more than extra fitness for beginners.
