## 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.
हल किया गया उदाहरण
You ran a 5K (3.1 miles) in 25 minutes and want to predict your half marathon time.
- 01Distance ratio = 13.1 / 3.1 = 4.2258
- 02Fatigue factor = 4.2258 ^ 1.06 = 4.6013
- 03Predicted time = 25 * 4.6013 = 115.03 minutes
- 04That is 1 hour, 55 minutes, and 2 seconds
- 05Predicted pace = 115.03 / 13.1 = 8.78 min/mile
अक्सर पूछे जाने वाले प्रश्न
How accurate is the Riegel formula?
It is typically accurate within 2-5% for trained runners racing distances from the mile to the marathon, assuming proper training for the target distance.
What is the fatigue exponent?
The 1.06 exponent models the fact that you cannot maintain the same pace over longer distances. Higher exponents predict more slowdown.
Can I use this for ultramarathons?
The formula becomes less reliable beyond the marathon because fatigue factors like nutrition, sleep, and terrain play a much larger role.
