Find your pace per mile and per kilometer from any distance and time.
About this running pace calculator
Pace is the time it takes to cover one mile or one kilometer, and it's how runners plan training and race strategy. Enter a finish time for a race or workout and this calculator converts it into pace per mile, pace per kilometer and average speed.
Use it to set goal paces for a 5K, 10K, half marathon or marathon, or to check how fast a training run really was.
How to use the Running Pace Calculator
- Choose a race distance or enter a custom distance.
- Enter your finish time in hours, minutes and seconds.
- Read your pace per mile and per kilometer, plus speed.
How pace is calculated
Pace = total time ÷ distance
One mile is exactly 1.609344 km. Speed is distance ÷ time, converted to miles or kilometers per hour.
Worked example
A 5K in 28:30 is a pace of about 9:10 per mile or 5:42 per kilometer — an average speed of 6.54 mph.
Tips for better results
- Run easy training runs 60–90 seconds per mile slower than your 5K race pace.
- GPS watches can overestimate distance on curvy routes; race distances are measured precisely.
