health.running-economy Calculator
Calculates running economy (oxygen cost per km) from VO₂ and speed, and predicts race time from VO₂max and lactate threshold. Running economy explains why elite marathoners with similar VO₂max have different race times — better economy means the same effort goes further.
Inputs
Speed M S
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Vo2 Ml Kg Min
Reference formula or conversion factor shown for context.
Rer
Reference formula or conversion factor shown for context.
Results
running economy RE (mL/kg/m)
Sample size or count used in the calculation.
energy cost (kJ/kg/km)
The total monetary cost computed for the given inputs.
RE classification
Category assigned based on where the computed value falls on a defined scale. Check which standard or guideline defines these boundaries.
caloric equivalent (kcal/L O₂)
Sample size or count used in the calculation.
RE = VO₂/v (mL O₂ per kg per metre)
Reference formula or conversion factor shown for context.
