Free running pace calculator for runners of all levels. Calculate your pace per kilometer or mile from distance and time, estimate your finish time for any race distance, or find out how far you can run at a given pace. Get per-kilometer split times and see equivalent paces for popular race distances including 5K, 10K, half marathon, and marathon.
Choose a calculation mode: calculate your pace from distance and time, calculate your finish time from distance and pace, or calculate distance from time and pace. Use the race preset buttons to quickly fill in common race distances like 5K, 10K, half marathon (21.1 km), and marathon (42.2 km). The calculator instantly shows split times and equivalent race paces.
Running pace is expressed as minutes per kilometer (min/km) or minutes per mile (min/mile). A faster pace means a lower number. For example, a 5:00/km pace is faster than a 6:00/km pace. Use split times to track your progress during training and races. This calculator supports both metric and imperial units with automatic conversion.
