PUTTING IT INTO PRACTICE
Running Speed: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Pace (minutes/km) | 6 |
| Result | 10 km/h |
- Check the input labels and enter the example values above.
- Apply the relationship: Speed (km/h) = 60 ÷ pace.
- The result is 10 km/h, rounded for display.
How to interpret your result
Enter decimal minutes: 5 minutes 30 seconds is 5.5.
Use matching distance units and decimal minutes. A constant-pace plan does not forecast how terrain, conditions or fatigue will affect a race. A split is a time over a chosen reference distance.
