How to use the Pace Calculator

  1. Pick what to solve for: Pace, Time, or Distance.
  2. Choose km or miles and pick a distance preset (5K, 10K, half, marathon, ultra) or enter a custom value.
  3. Enter the two known values (time as hh:mm:ss or mm:ss; pace as mm:ss per unit).
  4. Read pace per km, per mile, speed in kph/mph, calories burned and a full split-by-split schedule.
  5. Save the calculation with ★ and export via Share / CSV / PDF from the toolbar.

Pace, time and distance — the runner's triangle

Every running calculation is just rearranging time = distance × pace. This calculator solves any of the three from the other two and shows the same result in multiple units so you can plan around km signs, mile markers or treadmill speed displays.

Calories are estimated from MET values that scale with pace — faster pace pushes MET into the 12-20 range, easy jogging sits around 8-10. Multiply by body weight and duration in hours for kcal burned.

Splits are essential for race-day pacing: keep your first km/mile slightly slower than target and aim for a flat or slightly negative split to finish strong.
