Pace Calculator

The Formula

If you run 10 km in 50 minutes, your pace is 5:00 per km. From any two of the three values (pace, time, distance) you can calculate the third.

Pace vs Speed

Pace measures time per unit of distance (e.g. 5:30 min/km). Speed measures distance per unit of time (e.g. 10.9 km/h). Runners typically use pace because it maps directly to the effort you feel at each kilometre or mile marker.
