## Riegel Formula
**Predicted Time = Race Time x (Target Distance / Race Distance)^1.06**
The Riegel formula, developed by Peter Riegel in 1977, accounts for the fact that pace slows as distance increases. The exponent 1.06 captures this endurance fatigue factor.

Exemple Résolu
A runner who completed a 5K (3.1 miles) in 25 minutes.
- Marathon distance = 26.2 miles
- Distance ratio = 26.2 / 3.1 = 8.452
- Predicted time = 25 x 8.452^1.06
- = 25 x 9.55 = 238.7 minutes
- = 3 hours 58.7 minutes
- Pace = 238.7 / 26.2 = 9.11 min/mile
