Frequently Asked Questions About Pace Calculator
How do I calculate running pace?
Divide your total time by the distance. For example, 30 minutes over 5 km is 6:00 per km. This calculator does it for you and also converts to pace per mile and speed.
What is a good running pace?
It depends on fitness and distance. Many recreational runners average 6:00–7:00 per km (about 9:40–11:15 per mile). Use this tool to find your current pace, then aim to improve gradually.
How is pace different from speed?
Pace is time per distance (minutes per km or mile) and is how runners usually talk. Speed is distance per time (km/h or mph). This calculator shows both from the same input.
