FAQ
How is running pace calculated?
Pace is total time divided by distance. For 10 km in 50:00, that is 5:00 per km, which equals an average speed of 12 km/h.
What is the difference between pace and speed?
Pace is time per distance (minutes per km), while speed is distance per time (km/h). They describe the same effort from opposite directions.
Why enter minutes and seconds separately?
Splitting the fields avoids decimal-minute mistakes; the calculator combines them and handles the seconds rollover for an accurate pace.
Does the Running Pace Calculator send my data to a server?
No. The Running Pace Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
Worked example
Running 10 km in 50 minutes is a pace of 50 ÷ 10 = 5:00 min/km.
