Mathematical Formula & Scientific Methodology

Formula: Riegel 10K Race Prediction Model

T(10K) = T1 × (10.0 / D1)^1.06

Applies the 1.06 power scaling law to determine lactate threshold speed sustained over 10 kilometers.

Model Assumptions

  • Consistent weekly mileage
  • Adequate threshold training

Variables & Standard Units

SymbolPhysiological MeaningUnit
T1Benchmark performance timeseconds
D1Benchmark race distancekm

Scientific Limitations

  • Fatigue can be higher if moving up from 5K without sufficient weekly volume

Key Finding: T2 = T1 * (D2 / D1)^1.06. Fatigue exponent 1.06 models endurance degradation across running distances from 1500m to ultramarathon.
