Frequently Asked Questions
How do I calculate running pace?
Pace is your time divided by distance. Enter the distance you ran and your finishing time, and the calculator shows minutes per kilometre and per mile automatically.
What is a good running pace?
It depends on fitness and distance. Many recreational runners sit around 5:30–6:30 per km for easy runs; the right pace is one you can sustain for your target distance.
Can I use miles instead of kilometres?
Yes. Choose miles for the distance and the calculator still shows pace per km and per mile, plus speed in km/h.
How do I find my goal marathon pace?
Enter the marathon distance (42.195 km) and your goal finish time; the pace per km and per mile shown is the average pace you need to hold.
Is it free?
Yes — completely free, no sign-up, and it works in your browser on any device.
