Running Pace Calculator
Enter a distance and total time to get your pace per kilometer, per mile, and overall speed in km/h and mph.
Frequently asked questions
How do I use this to plan a race?+
Enter your goal finish time for the distance, and the per-km or per-mile pace it gives you is roughly what you'd need to hold, assuming an even pace, which most training plans work backward from.
Why do my per-km and per-mile paces look so different?+
A mile is about 1.6 times longer than a kilometer, so the same speed produces a slower-looking "per mile" number than "per km," even though it's the same pace.
Can I use this for cycling or swimming instead?+
It's built around running-distance presets (5K, 10K, half and full marathon), but the custom distance option works for any activity where pace per km or mile is meaningful.
