Pace tells you how long it takes to cover one kilometer or mile — the standard way runners compare effort and track progress across different race distances.
This calculator finds your pace per kilometer and per mile, plus your average speed, from any distance and finish time.
How it works
Enter the distance you covered and your finish time (hours, minutes, seconds). The calculator divides your total time by the distance to find your pace, converting between kilometers and miles automatically.
- Enter distance.
- Enter distance unit.
- Enter hours.
- Enter minutes.
- Enter seconds.
- Click Calculate to see your results.
Examples
A 10K in 50 minutes
Running 10 kilometers in 50 minutes works out to a pace of 5:00 per kilometer (8:03 per mile), at an average speed of 12 km/h.
A marathon finish time
Finishing a 42.2 km marathon in 4 hours means a pace of about 5:41 per kilometer (9:09 per mile).
Who should use it
- Finding your pace after a training run or race to track progress over time.
- Planning a target pace for an upcoming race based on a goal finish time.
Industry applications
- Running and endurance training
- Race planning and coaching
Advantages
- Reports pace in both min/km and min/mile, plus speed in km/h and mph.
- Works for any distance and finish time, not just standard race distances.
Limitations
- Calculates average pace over the whole distance — it doesn't account for splits or pacing strategy within the run.
Common mistakes to avoid
- Mixing up kilometers and miles when entering the distance, which produces a pace that looks right but is actually for the wrong unit.
- Forgetting to include hours for longer efforts like a marathon, leading to an incorrect total time.
Best practices
- Use your pace from a recent race or hard training effort (not an easy jog) when planning a race pace strategy, since easy-effort pace doesn't reflect race-day performance.
Tips
- Track your pace over time at an easy, consistent effort level to see genuine fitness improvements, separate from race-day adrenaline.
