Running Pace Calculator
Enter your distance and finish time to calculate your running pace and speed in all common units.
Pace vs Speed
Pace measures how long it takes to cover one unit of distance (e.g., 5:00/km).
Speed measures how much distance you cover per unit of time (e.g., 12 km/h).
They are reciprocals of each other:
Speed (km/h) = 60 ÷ pace (min/km)
Pace (min/km) = 60 ÷ speed (km/h)
