Running Pace Calculator
Calculate running pace, finish time or distance from any two inputs, with min/km, min/mile, km/h and mph conversions for race planning and treadmill workouts.
Pace bands are broad references and do not account for fitness level, heart rate, terrain, surface, weather or fatigue.

Calculate pace, time or distance
English search intent for a running pace calculator is practical race math: runners enter distance plus time to get pace, distance plus pace to get finish time, or time plus pace to estimate distance.
P - average pace, T - elapsed time, D - distance.
T - finish time at a steady average pace.
How to use the result
- Use min/mile for U.S. road races and many training plans.
- Use min/km for international races, GPS watches and metric workouts.
- Use speed in km/h or mph when matching treadmill settings.
- Treat the result as an average; hills, heat, wind, stops and fatigue change real race pace.
