Frequently Asked Questions

We use average MET (Metabolic Equivalent of Task) values. Running uses a factor of ~1.036 kcal/kg/km, and walking uses ~0.53 kcal/kg/km. Time is estimated based on 10 km/h for running and 5 km/h for walking.

Moving a heavier mass requires more energy. Therefore, a heavier person burns more calories covering the same distance as a lighter person.

Detailed Methodology & Calculation Logic

Burn Rate Logic

The calculator estimates the energy expended during physical activity based on body weight and metabolic factors.

  • Running Factor: We use a benchmark of 1.036 calories per kg per km for running.
  • Walking Factor: We use a benchmark of 0.53 calories per kg per km for walking.
Distance & Time Estimates

To determine the required effort, we reverse-calculate distance from your calorie goal and weight.

  • Distance Formula: Distance (km) = Calories / (Burn Factor × Body Weight).
  • Speed Benchmarks: Time is estimated using average speeds of 10 km/h for running and 5 km/h for walking.
