Choose 5K, 10K, half marathon, marathon or a custom distance." canonical: "https://www.numequo.com/conversion/speed/running-pace-calculator/" locale: "en" --- [Numequo](https://www.numequo.com/) › [Conversion](https://www.numequo.com/conversion/) › [Speed](https://www.numequo.com/conversion/speed/) # Running Pace Calculator Choose a distance and enter your target finish time. The split times assume an even pace from start to finish. ## Input data - **Race distance** - type: choice; default: 10; options: 5 km, 10 km, Half marathon (21.0975 km), Marathon (42.195 km), Other distance - **Distance (km)** - type: number; default: 15; min: 0.01; max: 1000; step: 0.001 - **Hours** - type: number; default: 0; min: 0; max: 99; step: 1 - **Minutes** - type: number; default: 50; min: 0; max: 59; step: 1 - **Seconds** - type: number; default: 0; min: 0; max: 59; step: 1 ## How it works Pace (seconds per km) = finish time in seconds ÷ distance in km. Speed (km/h) = distance ÷ time in hours. ## Quick examples - **10K in 50 min** - Race distance: 10, Hours: 0, Minutes: 50, Seconds: 0 - **Half in 2 h** - Race distance: 21.0975, Hours: 2, Minutes: 0, Seconds: 0 - **Marathon in 4 h** - Race distance: 42.195, Hours: 4, Minutes: 0, Seconds: 0 ## Understanding your result This is the average pace needed to hit your target, not a promise that every kilometre will take exactly the same time. The split times are checkpoints for an even effort. Last verified: 29 September 2026 (2026-09-29) ## Frequently asked questions ### How do I calculate running pace? Divide your finish time in seconds by the distance in kilometres, then convert the result into minutes and seconds per kilometre. ### Is 5:41 min/km the same as 5.41 decimal minutes? No. The 41 is seconds, so 5:41 min/km is about 5.683 decimal minutes per kilometre. ### Are half-marathon and marathon distances exact? The calculator uses 21.0975 km for a half marathon and 42.195 km for a marathon, not rounded 21.1 or 42.2 km. ### What do split times mean? They show the elapsed time you would see at each checkpoint if you maintained an even average pace. Start your watch when you cross the start line. ### Can I enter a distance other than 5K or 10K? Yes. Select Other distance and enter any distance from 0.01 to 1,000 km. ## Related calculators - [Kilometers per hour to Miles per hour Converter](https://www.numequo.com/conversion/speed/kmh-to-mph-converter/) - Convert kilometers per hour to miles per hour.
