Calorie Estimator
How Running Calorie Calculation Works
📊 MET-Based Calculation
We use Metabolic Equivalent of Task (MET) values based on your running speed. Faster paces burn more calories per minute due to higher energy demands.
⛰️ Terrain Adjustment
Hills and trails increase energy expenditure by 10-20% compared to flat roads. Treadmill running uses about 5% less energy due to no wind resistance and assisted leg return.
⚖️ Weight Matters
Heavier runners burn more calories per km because more energy is needed to move greater mass. This is reflected in the MET × body weight formula.
🎯 Accuracy Note
Calorie estimates have ±15% margin. Individual metabolism, fitness level, temperature, and running form all affect actual energy expenditure.
