Example result

Running result

55minutes

A smaller minutes-per-kilometer pace is faster. 5.5 minutes means 5 minutes 30 seconds, not 5 minutes 50 seconds.

Finish time55 minutes
Average speed10.91 km/h

6.5 minutes means 6 minutes 30 seconds. Uses the average over the whole distance, without adding separate stops.

Method and scope

Pace equals total minutes divided by kilometres. Estimated finish time equals pace in minutes per kilometre times distance.

A smaller minutes-per-kilometre pace means faster running. An average pace does not show changes of speed along the route.

Only the selected mode's pace or duration input is used. Terrain, rests and conditions may change actual performance; the estimate is not a training or race guarantee.

How the calculation works

Pace equals total minutes divided by kilometres. Estimated finish time equals pace in minutes per kilometre times distance.

Worked example

A 10 km run at 5.5 minutes per km takes 55 minutes. Enter 5.5 for five minutes 30 seconds, not 5.30.

Understanding the answer

A smaller minutes-per-kilometre pace means faster running. An average pace does not show changes of speed along the route.
