Running a mile burns roughly 80 to 140 calories for most people, with body weight being the single biggest factor. A 150-pound runner will burn about 105 to 120 calories per mile at a moderate pace, while a 200-pound runner covers the same distance for closer to 150 calories. The math is straightforward, and once you understand what moves the number up or down, you can estimate your own burn with reasonable accuracy.
Calories Burned by Body Weight
Your body weight does more to determine calorie burn than any other variable. Heavier bodies require more energy to move over the same distance. Here’s what the numbers look like at a common training pace of 6 mph (a 10-minute mile):
- 120 lbs: ~93 calories per mile
- 150 lbs: ~117 calories per mile
- 180 lbs: ~140 calories per mile
- 220 lbs: ~172 calories per mile
- 250 lbs: ~195 calories per mile
The pattern is nearly linear. For every additional 30 pounds of body weight, you can expect to burn roughly 25 more calories over a single mile. If you fall between two of those weight markers, splitting the difference gives you a solid estimate.
How Pace Changes the Equation
This is where things get counterintuitive. When you look at calories burned per mile (not per minute), pace matters less than most people assume. A 150-pound person running a relaxed 12-minute mile burns about 119 calories per mile, while that same person running a brisk 8.5-minute mile burns around 112 calories per mile. The numbers are surprisingly close.
The reason is simple: faster running burns more calories per minute, but you’re running for fewer minutes to cover the same distance. These two effects partially cancel each other out. Where speed really starts to make a difference is at racing paces. Once you push past about 8 mph (a 7.5-minute mile), the energy cost per mile climbs noticeably. At that pace, a 150-pound runner burns around 166 calories per mile, and at a 6-minute mile pace, that jumps to about 178 calories. At high speeds, your body recruits more muscles for stability, your stride mechanics become less efficient, and wind resistance increases, all of which demand extra energy.
For casual and moderate runners, the practical takeaway is that running a mile burns roughly the same number of calories whether you jog it or push the pace. The real advantage of running faster is that you cover more miles in the same amount of time.
Running vs. Walking the Same Mile
Running a mile burns roughly 30% more calories than walking the same distance. The difference comes down to biomechanics. Running involves a brief airborne phase with every stride, which forces your muscles to absorb and generate more force on each landing. Walking keeps one foot on the ground at all times, making it a more energy-efficient way to travel.
That gap narrows at the extremes. A fast power walk and a slow jog cover nearly the same speed range (around 4.5 to 5 mph), and at those crossover paces, calorie burn is much closer. If your goal is burning calories and you’re not concerned about time, walking more total miles can match or exceed the burn of a shorter run.
Hills and Incline
Running uphill is one of the fastest ways to increase your calorie burn per mile. For a 150-pound person, every 1% of incline adds roughly 10 extra calories per mile, an increase of about 12%. That means a moderately hilly route with an average grade of 3% to 5% could push your per-mile burn from 117 calories to 147 or higher, without running any faster.
If you run on a treadmill, even setting a 1% to 2% incline better simulates the energy cost of outdoor running, where wind resistance and terrain variation add effort that a flat belt doesn’t replicate.
The Afterburn Effect
Your body continues burning extra calories after you stop running. This post-exercise oxygen consumption helps restore your muscles, replenish energy stores, and bring your body temperature back to normal. For a typical mile at a moderate pace, this afterburn adds roughly 6% to 15% on top of the calories you burned during the run itself. On a 120-calorie mile, that’s an extra 7 to 18 calories.
The afterburn scales with intensity. A hard tempo mile or a sprint effort produces more post-run calorie burn than an easy jog. That said, for a single mile, the afterburn is a modest bonus rather than a game-changer. It becomes more meaningful during longer or higher-intensity workouts.
How to Estimate Your Own Burn
The most reliable quick method uses a value called a MET, which stands for metabolic equivalent of task. Every running speed has a published MET value. Running at 6 mph (a 10-minute mile) has a MET of 9.3, meaning it burns 9.3 times the energy your body uses at rest. Running at 7 mph (8.5-minute mile) is 11.0, and running at 8 mph (7.5-minute mile) is 12.0.
To calculate your burn per minute: multiply the MET value by your weight in kilograms (divide your weight in pounds by 2.2), then divide by 60. Multiply that result by how many minutes it takes you to run a mile, and you have your per-mile calorie burn. For a 150-pound person running 6 mph, that works out to 9.3 × 68.2 ÷ 60 = about 10.6 calories per minute, or roughly 106 calories for a 10-minute mile.
Why Your Fitness Tracker May Be Off
If you rely on a smartwatch to track calories, take the number with a grain of salt. Research from Harvard’s School of Engineering found that wearable devices can have estimated error rates of 30% to 80% for calorie burn. Some watches overestimate, others underestimate, and accuracy varies by brand, model, and activity type. Devices that use heart rate data tend to be more accurate than those relying on motion sensors alone, but none are precise enough to treat as exact.
For tracking trends over time, a watch is still useful. If you use the same device consistently, the relative changes (burning more this week than last) are more meaningful than the absolute numbers. Just don’t plan your post-run meal around whatever your wrist tells you.
