Running pace calculator
Work out your running pace in minutes per kilometre and per mile, plus your speed in km/h, from a distance and a finish time. Perfect for planning races, tempo runs and training targets.
Formula
Pace = total time ÷ distance. For 10 km in 50:00, that’s 5:00 per km (12 km/h). To hit a target finish time, multiply your goal pace by the race distance.
Common race paces
- 5K in 25:00 → 5:00 /km.
- 10K in 50:00 → 5:00 /km.
- Half marathon in 1:45 → ~4:58 /km.
