Running Pace Calculator
Enter a distance and finish time to get your pace per kilometre and mile, plus average speed in km/h and mph.
Understanding your running pace
Pace is simply how long it takes you to cover a set distance, usually expressed as minutes per kilometre or minutes per mile. It's the most practical way to gauge running effort, plan a race, and compare sessions. Enter the distance you ran and your finish time, and this calculator returns pace per kilometre, pace per mile, and average speed in both km/h and mph.
Because one mile is 1.609 kilometres, your per-mile pace is always a bigger number than your per-kilometre pace for the same run. Seeing both side by side is handy when race distances and training plans mix units, which they often do.
Using pace to train and race
To find the pace you need for a goal, divide your target time by the race distance. Want to break two hours in a half marathon? That's about 5:41 per kilometre for the full 21.1 km. Working backwards from a goal like this turns a vague ambition into a concrete number you can practise at.
Most training plans mix paces on purpose: easy runs build your aerobic base and should feel conversational, while shorter intervals at a faster pace build speed. Tracking pace over weeks shows whether your training is working, though remember that heat, hills, and wind all slow you down on a given day. Stay on top of hydration too — our water intake calculator gives a daily baseline.
Conversions use 1 mile = 1.609344 km. Pace and speed are computed directly from your inputs.
Frequently asked questions
How do I calculate running pace?
Pace is your finish time divided by the distance. Enter a distance and a time and this calculator returns your pace per kilometre and per mile, plus average speed in km/h and mph. It works for any distance, from a track rep to a marathon.
What is a good running pace?
It depends entirely on fitness, distance, and terrain, so there is no universal "good" pace. A more useful approach is to track your own pace over time and aim for gradual improvement. Many recreational runners jog somewhere around 6 to 7 minutes per kilometre.
How do I convert pace between km and miles?
One mile is 1.609 kilometres, so pace per mile is always a larger number than pace per kilometre for the same effort. This tool shows both at once, so you do not need to convert manually.
What pace do I need for a target finish time?
Divide your goal time by the race distance to get the required pace. For example, a sub-2-hour half marathon (21.1 km) needs about 5:41 per kilometre. Enter your target time and the distance here to see the exact pace you would need to hold.
