Custom Distance Pace Calculator & Race Card

Any race distance: enter the course length in km, then a goal time or pace, to get even splits and a shareable race card.

Target pace

Speed rounding

Treadmill speed is rounded up to 0.1 km/h, so the calculated setting is at least the target speed. Actual pace depends on treadmill calibration.

Plan 42.195 km even splits and export a race card. Example: 3:30:00 = approximately 4:58.6/km.

The main pace input is displayed rounded down to whole seconds; race finish times use the precise target pace. Choose Round up (default) or Round to nearest for treadmill settings in 0.1 km/h or mph steps. Round up gives a calculated setting at least as fast as the target. Round to nearest may be slightly faster or slower. Actual pace depends on treadmill calibration. On the TrainingPeaks page, Target pace is the workout target with your chosen adjustment, displayed to 0.1 second. It is not the actual pace produced by the rounded treadmill speed. Time and distance are estimated from target pace.
