Calculate calories burned running based on pace, distance, weight, and terrain. Includes MET values, net vs gross calories, and pacing strategies.
Running is a time-efficient way to raise energy expenditure, and the estimate depends mainly on body weight, distance, pace, and terrain. Hills and uneven surfaces can raise the cost, while flatter routes are easier to compare across sessions.
A simple rule of thumb is about 1 calorie per kilogram per kilometer, but the exact value varies with pace and route. That makes it useful to estimate both gross and net calories when you are planning food intake or comparing different run sessions.
This calculator uses MET values to estimate calorie burn and also shows net calories above resting expenditure.
Use this calculator when you want a practical estimate for fueling, weight planning, or comparing workouts. It is most useful when you want to compare the effect of pace, distance, and terrain instead of relying on a single rough rule of thumb.
Calories = MET × Weight(kg) × Duration(hours). Net Calories = Total Calories - Resting Calories. MET for running ranges from 6.0 (5 mph/12 min/mi) to 18.0 (10 mph/6 min/mi). Approximate rule: ~1.0 cal × weight(kg) × distance(km).
Result: 674 calories (gross), 605 calories (net)
At 5:30/km pace (10.9 km/h), 9.8 MET × 75 kg × 0.917 hr = about 674 calories gross. Net calories subtract resting expenditure for the same time, leaving about 605 calories.
Running energy cost is fairly consistent per unit of distance when normalized for body weight. That is why distance is often a better planning variable than pace when you want a quick estimate.
Faster paces burn more calories per hour, while the total for a fixed distance is often similar enough to compare across sessions. That makes pace useful for time-limited training and distance useful for total-session planning.
Running can support weight management, but results depend on the overall energy balance across food intake, training volume, and recovery. The calculator is best used as a rough planning aid rather than a promise of a specific weight change.

The calculator estimates running calories from MET values, body weight, and duration, then shows a net figure by subtracting resting expenditure over the same time. It is intended for training planning and comparison, not as a precise metabolic measurement.
Only slightly. The bigger effect of faster running is that it burns more calories per hour, even if the per-mile difference is modest.
Gross calories are the total calories burned during the run. Net calories subtract the energy you would have burned at rest during the same time, which can be more useful when you are tracking exercise against food intake.
Yes, hills usually increase calorie cost because the body has to do more work. The size of the increase depends on grade, speed, and how long the hill lasts.
A marathon can burn several thousand calories, but the total depends mainly on body weight and pace. Heavier runners generally burn more than lighter runners over the same distance.
Yes. Running usually has a higher calorie cost per mile than walking because the movement pattern is less economical, but the difference is smaller than many people expect.
Treadmill displays are rough estimates. They can be useful for comparison, but they should not be treated as exact calorie measurements.
