Pace Calculator
Calculate running pace, finish time or distance. Convert between pace per kilometre and pace per mile, use race presets, generate split tables, estimate speed, predict equivalent race times and view training pace zones.
Calculator
Pace = time ÷ distance. Time = pace × distance. Distance = time ÷ pace.
Race preset
Choose a common race distance or enter a custom distance.
Enter the race or training distance.
Hours, minutes and seconds.
Minutes and seconds per unit.
Distance between split rows.
Adjust split table pacing.
Used for equivalent race times.
Equivalent race predictions
Predictions are estimates only. Longer races depend heavily on endurance, fuelling, weather, course profile and pacing discipline.

How the pace calculation works
Pace is the time taken to cover one unit of distance. Runners usually use minutes per kilometre or minutes per mile.
Finish time = pace × distance
Distance = total time ÷ pace
Speed is the inverse of pace. For example, if you run 5:00 per kilometre, your speed is 12 km/h. Equivalent race predictions are estimated from your current result and adjusted depending on the selected model.
Note: Predictions are not guarantees. Course elevation, wind, heat, surface, fuelling, fatigue, training background and race-day execution all affect real finish times.
How to use a pace calculator well
Use even pacing for most races
An even or slight negative split is usually easier to sustain than starting too fast and fading.
Train at different speeds
Easy, long, tempo and interval runs should not all be the same pace. Different intensities develop different systems.
Check splits before race day
Knowing target splits helps you stay controlled early and avoid chasing an unrealistic pace.
Adjust for conditions
Heat, hills, wind and trail surfaces can all require a slower target pace than a flat road estimate.
