Swimming Pace: Reading Your 100-Metre Number
A per-100-metre pace turns any swim into a comparable number. This post shows how to use it for intervals and steady swims.
What is the Swimming Pace Calculator?
Enter the distance you swam and the time it took, and the tool scales the result to a standard 100-metre pace. That makes swims of different lengths easy to compare and gives a clear number for planning intervals.
How to use it
- Enter the distance you swam in metres.
- Enter the time in minutes and seconds.
- Click Calculate Pace.
Worked example
1000 metres in 20 minutes gives a pace of 2 minutes per 100 metres.
How do I use pace for intervals?
Pick a target pace, then set each repeat's send-off time from it, leaving a short rest between repeats so the pace stays honest.
Frequently asked questions
Does pool length change the pace?
No, pace per 100 metres is length-independent, though turns make short pools slightly faster.
What if I swam open water?
The maths still works, but currents and sighting make open-water pace less repeatable.
