What does this tool do?
Pace is time per unit distance; speed is distance per unit time. This calculator accepts hours, minutes and seconds and shows both, plus the time needed for a half marathon and marathon at the same pace.
The Formula
Pace = Time ÷ Distance; Speed = Distance ÷ TimeFrequently Asked Questions
What is a good running pace?
It depends on experience, distance and goals. Compare with your own recent race times rather than a universal benchmark.
How do I convert pace to speed?
Speed (km/h) = 3600 ÷ pace in seconds per kilometre. A 5:00/km pace is 12 km/h.
