Predictor de Tiempo de Carrera — Fórmula
## How the Riegel Race Prediction Formula Works
The Riegel formula predicts race times across distances based on a known performance.
### Formula
**T2 = T1 x (D2 / D1) ^ 1.06**
Where:
- **T1** = Known race time
- **D1** = Known race distance
- **D2** = Target race distance
- **1.06** = Fatigue exponent
The formula works best for distances between 1500 m and the marathon, assuming similar fitness and training for both distances.

Ejemplo Resuelto
You ran a 5K (3.1 miles) in 25 minutes and want to predict your half marathon time.
- Distance ratio = 13.1 / 3.1 = 4.2258
- Fatigue factor = 4.2258 ^ 1.06 = 4.6013
- Predicted time = 25 * 4.6013 = 115.03 minutes
- That is 1 hour, 55 minutes, and 2 seconds
- Predicted pace = 115.03 / 13.1 = 8.78 min/mile
