Running Pace Calculator

Calculate your running pace from distance and time. Get your pace per kilometer and per mile, plus estimated finish times for common race distances.

Time

How Running Pace is Calculated

Pace = Total Time ÷ Distance
Speed (km/h) = Distance (km) ÷ Time (hours)

Your pace is the time it takes to cover one unit of distance (one kilometer or one mile). A lower pace number means faster running.

Example: Running 5 km in 25 minutes
Pace = 25 min ÷ 5 km = 5:00 min/km
Pace per mile = 5:00 × 1.60934 = 8:03 min/mile
Speed = 5 ÷ (25/60) = 12.0 km/h
