What is this calculator?
Convert distance and time into pace per km and average speed. The formula, a worked example, and a reference table are below. Results are for education only, not medical advice.
How it works
Pace (min/km) = time (min) ÷ distance (km); speed (km/h) = distance ÷ (time ÷ 60).
Example
5 km in 28 min 5:36/km pace and ~10.7 km/h average speed.
Reference Table
| Value | Meaning |
|---|---|
| 5K | Often 4:30–7:00/km for recreational runners |
| Half marathon | Slower than 5K race pace |
| Trail | Elevation slows pace vs road |
FAQ
