How to use the Pace Calculator
- Choose kilometers or miles and enter the completed distance.
- Enter elapsed hours, minutes, and seconds.
- Use pace for split planning and speed for a distance-per-hour comparison.
How the calculation works
Pace = elapsed time ÷ distanceDistance is normalized to kilometers. Pace is displayed per kilometer and per mile, while average speed divides distance by elapsed hours.
Example calculation
Completing 10 km in 50 minutes gives a pace of 5:00 per kilometer, about 8:03 per mile, and an average speed of 12 km/h.
How to interpret the result
Average pace smooths hills, stops, and speed changes across the full activity. Race-course distance and device measurements can differ slightly.
Notes and assumptions
- Elapsed time and distance cover the same activity.
- Pauses are included if they are part of the entered elapsed time.
- Training decisions should consider fitness, conditions, and health, not pace alone.
