About this tool
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.
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.
