Running Pace Calculator
Convert between running pace (min/km or min/mi), speed (km/h or mph), and race finish time - free, instant, for any distance.
Whether you're training for a 5K or a marathon, understanding the relationship between pace, speed, and finish time is essential. Our free running pace calculator lets you convert instantly between pace (minutes per kilometer or per mile), speed (km/h or mph), and finish time for any distance. Enter one value and get all the others - plus per-kilometer splits and projected times for common race distances (5K, 10K, half marathon, marathon). Useful for planning race strategy, setting training targets, or comparing performances across distances.
Calculate Pace and Speed
Enter your pace in min:sec per km to calculate speed and finish time.
Format: minutes:seconds per kilometer (e.g. 5:30 = 5 min 30 sec per km).
How to Calculate Running Pace
Running pace is the time it takes to cover one unit of distance. The formula is simple: Pace = Time / Distance. For example, if you run 5 km in 25 minutes, your pace is 25 / 5 = 5:00 min/km.
To convert pace to speed, divide 60 by your pace in minutes. A 5:00 min/km pace equals 60 / 5 = 12 km/h. To convert speed to pace, divide 60 by your speed in km/h.
For imperial units, the same formulas apply with miles. A 8:00 min/mile pace equals 60 / 8 = 7.5 mph. To convert between min/km and min/mile, multiply min/km by 1.609 to get min/mile.
