Enter a distance and time to get your running pace per mile and per kilometre, plus your speed.
How the pace calculator works
This pace calculator turns a distance and finish time into your pace per mile and per kilometre, and your speed. It’s ideal for planning race splits or checking training runs.
Enter the distance in miles or km and the time in hours, minutes and seconds.
Step by step
- Enter the distance and its unit.
- Enter the time as hours, minutes and seconds.
- Read your pace per km, per mile and your speed.
How the number is calculated
pace per km = time ÷ distance(km)
speed (km/h) = distance(km) ÷ hours
A worked example
Worked through, a distance of 5 produces a pace of 5:00. Underneath, Pace / km comes out at 5:00 /km and Pace / mile at 8:03 /mi. Change any field and every figure updates as you type.
Frequently asked questions
How do I calculate running pace?
Divide your total time by the distance. For 25 minutes over 5 km, that’s 5:00 per km.
How do I convert pace between miles and km?
A mile is about 1.609 km, so your per-mile pace is roughly 1.609 times your per-km pace.
What pace do I need for a goal time?
Divide your goal time by the race distance. This tool shows the pace directly once you enter the numbers.
