Running Pace Calculator
Turn a race distance and finish time into pace, speed, and common-distance projections.
Pace per km
5:00 /km
Pace per mile
8:03 /mi
Average speed
12.00 km/h
This is an average pace. Hills, stops, GPS error, weather, and course length can change an actual race split.
From finish time to training pace
Distance divided by elapsed time gives average pace per kilometer. Mile pace and average speed are derived from the same inputs, without claiming to predict a future race result.
Example
A 5 km finish in 25:00 equals 5:00/km and about 8:03/mile.
