Pace Calculator
Calculate running pace and average speed based on distance and time.
How to Use the Pace Calculator
Enter distance and total time to calculate average pace per unit of distance and an equivalent speed.
Practical Example
Running 10 km in 50 minutes gives an average pace of 5:00 per kilometer.
Factors That Affect the Result
Terrain, elevation, weather, stops, GPS accuracy and uneven pacing can make real effort differ from the simple average.
Frequently Asked Questions
What is running pace?
It is the time needed to cover one unit of distance.
Is pace the same as speed?
No. Pace is time per distance, while speed is distance per time.
Can I use miles instead of kilometers?
Yes if the selected distance unit matches the result you want.

Using Pace to Plan a Run or Walk
Pace tells you how much time you need to cover a unit of distance, commonly minutes per kilometer or minutes per mile. It is different from speed: pace is time per distance, while speed is distance per time. The calculator helps convert a known finish time and distance into an average pace or estimate a finish time from a target pace.
Worked Pace Example
If you complete 10 kilometers in 50 minutes, your average pace is 5:00 per kilometer. Holding that average would produce a 25-minute 5K, although real races rarely have perfectly even splits because hills, weather, fatigue, turns, and aid stations affect individual kilometers.
How to Use the Result
Use average pace as a planning reference rather than a guarantee. Training runs may intentionally be slower or faster depending on the workout. When comparing mile and kilometer pace, make sure the distance unit matches the pace unit. GPS rounding and course measurement can also create small differences between the calculated pace and the value shown on a watch or race result.
Pace, Speed and Finish Time
Pace expresses the time required to cover a unit of distance, while speed expresses distance traveled per unit of time. A lower minutes-per-kilometer or minutes-per-mile value means a faster pace. Pace can also be used with distance to estimate finish time.
Real-World Pace Variation
Terrain, elevation, weather, stops, GPS accuracy and fatigue can make actual pace vary throughout a run or walk. An average pace is useful for planning, but it does not imply that every segment was completed at the same pace.
