Your pace
5:00 per km
8:03 per mi · 5.00 km in 25:00
| Split | Elapsed time |
|---|---|
| 1 km | 5:00 |
| 2 km | 10:00 |
| 3 km | 15:00 |
| 4 km | 20:00 |
| 5 km | 25:00 |
Start a little slower than goal pace — negative splits feel amazing at the finish!
How it works
- Pace = time ÷ distance
- Time = pace × distance
- Distance = time ÷ pace
Race presets: 5K = 5 km, 10K = 10 km, half marathon = 21.0975 km, marathon = 42.195 km. Splits show your elapsed time at each kilometre or mile if you hold an even pace.
Worked example
A 10K in 50:00 → 50 min ÷ 10 km = 5:00 per km (about 8:03 per mile). Your 5 km split would be 25:00.
Questions people ask
Anywhere from 6:00 to 8:00 per km (10–13 min per mile) is very normal for new runners.
