Mathematical Formula & Scientific Methodology

Formula: Standard Athletic Pace Formula

Pace = Total Duration / Total Distance

Computes reciprocal speed formatted as time per unit distance.

Model Assumptions

  • Uniform steady pace

Variables & Standard Units

Pace (min/km)Seconds per kilometer converted into MM:SS formatdimensionless
SpeedDistance / (Seconds / 3600)km/h or mph

Scientific Limitations

  • Terrain undulations and wind conditions cause fluctuations in instantaneous pace
