Pace Calculator
Pace is one of the most useful numbers for a runner — it turns a distance and time into a per-kilometre or per-mile rate you can use to plan training runs or predict race splits.

What is Pace?
Pace expresses how long it takes to cover one kilometre (or mile) at a steady rate — it is simply your total time divided by your total distance.
Pace Formula
Your finish time is converted to total minutes, then divided by the distance to get a per-kilometre pace. That figure is converted to per-mile pace using the km-to-mile conversion factor, and to an average speed by dividing distance by time in hours.
Pace (min/km) = Total Time (minutes) ÷ Distance (km) Speed (km/h) = Distance (km) ÷ Total Time (hours)
Pace Example
Running 5 km in 25:00: pace = 25 ÷ 5 = 5:00 min/km; speed = 5 ÷ (25/60) = 12 km/h.
How to Use This Calculator
- Enter the distance you ran (or plan to run) in kilometres.
- Enter your finish time (or target time) in hours, minutes and seconds.
- Select "Calculate" to see your pace per kilometre, per mile, and average speed.
Limitations
- This calculates average pace over the whole distance — it does not account for elevation gain/loss, terrain, wind, or pacing strategy (negative/positive splits).
- Useful for flat-course training and race-time planning, not a guarantee of actual race-day performance.
- Treat results as a training and planning tool rather than a precise physiological measurement.
Frequently Asked Questions
Enter your goal finish time and race distance to see the pace per kilometre you will need to hold — useful for setting mile/km splits during the race.
This varies enormously by individual, but many beginners run comfortable training paces in the 6:30-8:00 min/km range — the more useful benchmark is your own improvement over time, not a universal number.
Yes — the pace and speed math is identical for any steady-rate distance activity (walking, running, cycling), only the typical pace ranges differ.
