- Enter the two known values. Time is entered as hours, minutes and seconds; pace as minutes and seconds per km or mile.
Formel
Pace, time and distance are linked by a simple equation. Race predictions use Riegel's formula, which accounts for slowing down over longer distances.
pace = time / distance
time = distance × pace
Riegel: T₂ = T₁ × (D₂ / D₁)^1.06
Example
- 10 km in 50:00 → pace = 3,000 s / 10 = 300 s = 5:00 per km.
- Per mile: 5:00 × 1.609344 ≈ 8:03 per mile; speed 12 km/h.
- Predicted half marathon: 50:00 × 2.10975^1.06 ≈ 1:50:21.
Häufige Fragen
How accurate are race predictions?
Riegel's formula works well for trained runners between about 3 minutes and 4 hours of effort. Predictions for the marathon are often optimistic unless you've done the long-run training.
What is a good running pace?
It depends on age, experience and distance. For many recreational runners, 5:30–7:00 per km (9–11 minutes per mile) is a comfortable training pace.
How do I convert min/km to min/mile?
Multiply the pace in seconds per km by 1.609344. For example, 5:00/km × 1.609344 = 8:03/mile.
