Running pace and split calculator

Enter distance and finish time to calculate average pace per km and mile plus cumulative split times.

Enter a distance greater than zero, up to three decimal places.

Finish time

Enter hours, minutes, and seconds separately. Enter 0 for unused parts; total time must be 24 hours or less.

Use the selected distance unit. The last split may be shorter; up to 100 splits.

Distance and time are calculated in this browser only and are not saved or sent to a server.

Result

Enter the distance, time, and split interval, then calculate.

Getting started

Choose km or miles, enter distance and finish time, then set a split interval in the same unit. View average pace and each segment’s time.

Rules and limits

Average pace is finish time ÷ distance. Cumulative split times use the same fraction of total time as cumulative distance and round to seconds; the final time equals your finish time.

Limits: 1,000 km equivalent, 24 hours, and 100 splits. Results are arithmetic based on your inputs, not GPS measurements, coaching, medical advice, or course adjustments.
