Quick Answer
How do you calculate running pace?
// Answer
Pace is your time divided by distance, expressed as minutes per kilometer or mile. Running 10 km in 50 minutes is 50 ÷ 10 = 5:00 per km. Speed is the inverse: distance divided by time, here 12 km/h.
Common race paces
| Pace /km | 10K time | Half marathon | Marathon |
|---|---|---|---|
| 5:00 | 50:00 | 1:45:29 | 3:30:59 |
| 6:00 | 1:00:00 | 2:06:35 | 4:13:10 |
| 4:30 | 45:00 | 1:34:56 | 3:09:53 |
Times assume an even pace over the official distances: 10 km, a half marathon of 21.0975 km and a marathon of 42.195 km (World Athletics).
