Pace Calculator
Calculate your running or cycling pace, time, or distance. Enter any two values and the calculator solves for the third. Results are shown in both metric and imperial units.
Pace is the inverse of speed: it tells you how many minutes it takes to cover one kilometre or one mile. Runners typically think in pace (min/km or min/mi), while cyclists often prefer speed (km/h or mph). This calculator converts freely between all four formats and supports common race distances with one-click buttons. All calculations are instant -- just type and the results update automatically.
About Pace vs Speed
Pace measures the time it takes to cover a unit of distance (e.g., 5:30 per km). Speed measures the distance covered per unit of time (e.g., 10.9 km/h). They are inversely related: a faster pace means a higher speed.
To convert pace to speed, divide 60 by the pace in minutes. For example, a pace of 6:00 /km equals 60 / 6 = 10 km/h. To convert speed to pace, divide 60 by the speed.
