Predicted Marathon Time (min) vs Recent Race Time
Formula
## 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.
Exemplo Resolvido
A runner who completed a 5K (3.1 miles) in 25 minutes.
- 01Marathon distance = 26.2 miles
- 02Distance ratio = 26.2 / 3.1 = 8.452
- 03Predicted time = 25 x 8.452^1.06
- 04= 25 x 9.55 = 238.7 minutes
- 05= 3 hours 58.7 minutes
- 06Pace = 238.7 / 26.2 = 9.11 min/mile
Perguntas Frequentes
How accurate is the Riegel formula?
The Riegel formula is reasonably accurate for well-trained runners. It may overestimate for beginners and underestimate for elite runners.
Does training matter?
Yes. This prediction assumes you train adequately for the marathon distance. A 5K time alone does not guarantee marathon performance without proper long-run training.
