Running pace calculator

Pace, finish times and treadmill speed on one shareable card.

Target pace

Pace rounds down, treadmill speed rounds up — both err slightly fast, so the target is still met. Times use the exact pace.

Calculate pace, finish time and speed. Export a clear race card or track split table.

Pace in the main calculator input is shown rounded down to whole seconds; finish times use the precise value. Treadmill speed is rounded up to the next 0.1 km/h (or mph). For example, 4:15/km converts to about 14.118 km/h, so the treadmill setting is 14.2 km/h, which gives about 4:13.5/km. On the TrainingPeaks page, Target pace means the workout target including your chosen adjustment, displayed to 0.1 second. It is not the actual pace produced by the rounded treadmill speed. Times and total distance are estimated from target pace.
