Turn a distance and finish time into your running pace per kilometre and per mile, plus your average speed. Use it to plan race splits or to check what a training run worked out to.
How this is calculated
Pace is the total time divided by the distance, converted to a minutes-and-seconds figure for each unit, with kilometres and miles related by 1 mile = 1.609344 km. Average speed is the distance divided by the time in hours. Pace seconds are rounded to the nearest whole second.
How to use
- Enter the distance and choose kilometres or miles.
- Enter the finish time as hours, minutes, and seconds.
- Read your pace per kilometre, pace per mile, and average speed.
Examples
- 10 km in 50:00:
5:00 /km, 8:03 /mi, 12 km/h - 5 mi in 40:00:
4:58 /km, 8:00 /mi, 7.5 mph
FAQ
- What is the difference between pace and speed?
- Pace is time per unit of distance, such as 5 minutes per kilometre, so a smaller number is faster. Speed is distance per unit of time, such as 12 km/h, so a larger number is faster. This tool shows both from the same run.
- How do you convert pace between km and miles?
- One mile is 1.609344 kilometres, so a pace per kilometre is multiplied by that factor to get pace per mile. The tool does the conversion for you and rounds each pace to the nearest second.
