Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| Distance | Numeric value. Unit: km. Minimum: 0.001. Maximum: 10000. | 5 |
| Finish time | Numeric value. Unit: minutes. Minimum: 0.001. Maximum: 100000. | 30 |
Result for these sample inputs
6:00 min/km
- Speed (km/h)
- 10
- 5 km at this pace (minutes)
- 30
- 10 km at this pace (minutes)
- 60
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Pace = time in minutes ÷ distance in kilometers. Speed = distance ÷ (minutes ÷ 60).
A 5 km run in 30 minutes is a 6:00 min/km pace and an average speed of 10 km/h.
What to keep in mind
The result is an average; hills, stops and acceleration are not modeled. Times for 5 km and 10 km assume you maintain the same pace.
Common questions
How do I enter 30 minutes 30 seconds?
Use 30.5 minutes. Convert seconds to a fraction of a minute by dividing by 60.
Is the 10 km time a race prediction?
No. It simply extends the same average pace to 10 km. It does not model fatigue or training.
