Plans, paces & PBs Calculate Pace
Enter a distance and total time. Use this after a run or race to find your average min/km and min/mile pace.
Running Pace Calculator
Running Pace Calculator
Calculate pace per kilometre or mile, predict a finish time, or work out how far you covered. Enter any two of distance, time and pace and the calculator will do the remaining running maths.
Cumulative Splits
Pace comparison
Finish times across common distances
Your calculated pace is highlighted, with two slightly faster and two slightly slower options alongside it.
How to use it
Choose the answer you need.
The calculator changes the required fields so you only enter the two values you already know.
Calculate Finish Time
Enter a distance and your intended pace. Use this to see what an even pace would produce over 5K, 10K, a half marathon or marathon.
Calculate Distance
Enter how long you ran and your average pace. This is useful for timed runs, treadmill sessions and distance estimates.
Popular examples
5K, 10K, half-marathon and marathon paces.
These examples use even average pace. Your individual race splits may vary with hills, wind and course conditions.
| Distance | Finish time | Pace per km | Pace per mile |
|---|---|---|---|
| 5K | 20:00 | 4:00/km | 6:26/mile |
| 5K | 22:00 | 4:24/km | 7:05/mile |
| 5K | 25:00 | 5:00/km | 8:03/mile |
| 5K | 30:00 | 6:00/km | 9:39/mile |
| 10K | 40:00 | 4:00/km | 6:26/mile |
| Half marathon | 2:00:00 | 5:41/km | 9:09/mile |
| Marathon | 4:00:00 | 5:41/km | 9:09/mile |
How pace, time and distance fit together
PaceTime ÷ distance
Finish timePace × distance
DistanceTime ÷ pace
Always use matching units. A pace entered per mile must be converted before multiplying it by a distance measured in kilometres; the calculator handles this automatically.
Average pace is a guide, not a metronome.
Average pace describes the whole run. It does not mean every kilometre must be identical. Inclines, corners, wind and congestion can all create sensible variation.
For training, use pace alongside effort. Easy running should remain controlled even when heat, hills or tired legs make the number slower than usual.
What next?
Turn the number into useful training.
Average pace is most useful when it leads to the right goal and the right session intensity. Compare our 5K training plans or 10K training plans to turn your current pace into a realistic next target.
Frequently Asked Questions
Running pace questions
How do I calculate my running pace?
Divide your total running time by the distance covered. A 25-minute 5K is 5:00 per kilometre or approximately 8:03 per mile.
What is the difference between pace and speed?
Pace is the time taken to cover a unit of distance, usually minutes per kilometre or mile. Speed is the distance covered in an hour, usually kilometres per hour or miles per hour.
How do I convert min/km to min/mile?
Multiply seconds per kilometre by 1.609344 to get seconds per mile. The calculator performs that conversion automatically in either direction.
Can I calculate finish time from pace?
Yes. Choose Finish time, select the race distance, then enter your pace per kilometre or mile. The calculator returns the total time and cumulative splits.
Why does my watch show a different pace?
GPS watches estimate distance from location samples, so corners, tree cover, tall buildings and short laps can affect the reading. A measured race distance and official finish time usually give the most reliable average pace.
Should every kilometre of a race be exactly the same pace?
Not necessarily. Hills, wind, congestion and fatigue all affect individual splits. Average pace is the useful overall target; small variations are normal.
