How to use this tool

Choose whether to solve for pace, finish time or distance, then select kilometers or miles.

Finish time uses hours:minutes:seconds; pace uses minutes:seconds per distance unit. The split sheet assumes a constant pace.

Pace = time / distance; time = pace × distance; distance = time / pace

Worked example

5:00 / km · average pace

Fixed example using the settings below. Monetary examples use USD; dates and times use their stated reference values. This example stays unchanged when you edit your calculation.

Example inputs
  • Solve for: Pace
  • Distance unit: Kilometers
  • Distance: 5
  • Finish time (hours:minutes:seconds): 0:25:00

Method illustration: 5 km in 25 minutes is 5:00 per kilometer, or about 8:03 per mile.

Assumptions and limits

  • Assumes a constant pace. Splits are proportional planning estimates, not race-performance predictions.
  • Distances and times must be positive. Pace uses minutes:seconds, while finish time uses hours:minutes[:seconds].
