Running Pace Calculator

Enter the distance and your time to see the pace you ran. Or enter the pace you want to hold and we'll give you your finish time and a split for every kilometer. Pace per mile is shown too.

How pace is calculated

Pace is the time it takes you to cover one kilometer: pace = time ÷ distance. If you run 10 km in 50 minutes, your pace is 5:00 min/km (8:03 min/mile). Speed is the inverse: speed = distance ÷ time, in this case 12 km/h.

Tips for using your pace

On easy runs, go 60-90 seconds per kilometer slower than your 10K pace.
Start at an even pace: going out 10 seconds per kilometer too fast usually costs you minutes at the end.
Your race pace changes with heat, hills and wind: use it as a guide, not a rule.
