Do you burn more calories running faster or longer?
Running faster burns more calories per minute, but total distance is the primary determinant of total calories burned (roughly 100 kcal per mile for an average runner).
Running Calorie Calculator
Calculates energy expenditure and METs for outdoor running and treadmill workouts using the official American College of Sports Medicine (ACSM) metabolic running equation.
Scientific Formula & Exercise Physiology Standards
Equation: ACSM Metabolic Equation for Running | Peer-Reviewed Source: American College of Sports Medicine Guidelines for Exercise Testing and Prescription
VO2 (ml/kg/min) = (0.2 × Speed m/min) + (0.9 × Speed m/min × Grade) + 3.5
Converts VO2 oxygen uptake into METs (VO2 ÷ 3.5), then multiplies by weight and time: Calories = (MET × 3.5 × Weight kg ÷ 200) × Minutes.
Step-by-Step Worked Example: 30-Minute Run at 10 km/h (70 kg Runner)
- Calculate VO2 = (0.2 × 166.7) + 0 + 3.5 = 36.84 ml/kg/min
- MET = 36.84 ÷ 3.5 = 10.53 METs
- Calories = (10.53 × 3.5 × 70 ÷ 200) × 30 = 386.8 kcal
Calculation Result: Total Calories Burned = 387 kcal (12.9 kcal/minute)
Clinical Nuances, Limitations & Best Practices
- Running economy and wind resistance can introduce slight variations in outdoor running energy expenditure.
