Running Calorie Calculator
Estimate how many calories you burn running based on your weight, pace, and distance or duration. Uses MET-based methodology from the Compendium of Physical Activities.

Enter your weight, running pace, and either distance or duration.
Calories Burned Running by Weight & Pace
This reference table shows estimated calories burned per mile at common paces for different body weights.
| Pace | 120 lbs | 140 lbs | 160 lbs | 180 lbs | 200 lbs |

Values are estimates based on MET methodology. Actual calories vary by individual metabolism, terrain, and conditions.
How Running Calorie Calculations Work
The MET Method
This calculator uses MET (Metabolic Equivalent of Task) values from the Ainsworth Compendium of Physical Activities — the gold standard in exercise physiology research. The formula is:
Calories = MET × Weight (kg) × Duration (hours)
MET values represent the energy cost of an activity as a multiple of your resting metabolic rate. Walking has a MET of ~3.5, while running at 6:00/mile pace has a MET of ~14.5.
Factors That Affect Calorie Burn
- Body weight — Heavier runners burn more calories per mile because it takes more energy to move more mass.
- Pace — Faster running burns more calories per minute, but slightly fewer per mile. The difference per mile is small; the main factor is weight.
- Terrain — Hills, trails, and soft surfaces (sand, mud) increase energy cost by 10–30% compared to flat pavement.
- Temperature — Running in extreme heat or cold increases calorie burn as your body works to regulate temperature.
- Running economy — More efficient runners burn fewer calories at the same pace. Economy improves with training.
Running vs. Walking Calories
A common claim is that you burn the same calories running a mile as walking it. This is approximately true — running burns only about 10–20% more calories per mile than walking. However, running burns far more calories per minute because you cover ground faster. A 160-lb runner burns about 110 calories per mile running at 9:00/mi (12.2 cal/min) vs. about 90 calories walking the same mile at 20:00/mi (4.5 cal/min).
Calorie Burn for Weight Loss
Running is one of the most efficient calorie-burning exercises. A rough rule of thumb: you burn approximately 100 calories per mile (for a 150-lb person). To lose 1 pound of fat requires a deficit of approximately 3,500 calories — equivalent to about 35 miles of running. Sustainable weight loss combines moderate calorie deficit with consistent training.

Running Calorie Calculator FAQ
On average, running burns about 80–120 calories per mile depending on body weight. A 150-lb person burns roughly 100 calories per mile, while a 200-lb person burns about 130. Pace has a smaller effect — the main factor is how much you weigh.
Running faster burns more calories per minute but only slightly more per mile. At 8:00/mile pace you might burn 12 cal/min, while at 10:00/mile you burn about 10 cal/min. Per mile, the difference is only 5–15%. The biggest factors are body weight and total distance.
Close, but not exactly. Running burns about 10–20% more calories per mile than walking the same distance because of the bouncing motion and higher muscle activation. The bigger difference is time: running a mile takes 7–12 minutes vs. 15–20+ minutes walking, so running burns far more calories per minute.
MET stands for Metabolic Equivalent of Task. A MET of 1.0 is your resting energy expenditure (sitting quietly). Running at 6 mph has a MET of ~9.8, meaning it burns about 9.8 times the energy of sitting still. MET values are the most widely used standard for estimating exercise calorie burn in sports science.
MET-based estimates are typically within 15–20% of actual calorie burn for most people. Individual metabolism, fitness level, running economy, and environmental conditions all affect the actual number. For precise measurement, you'd need a metabolic testing lab with indirect calorimetry.
