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.
How Running Pace is Calculated
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.
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
