Running one mile burns roughly 80 to 140 calories for most people, with body weight being the single biggest factor. A 130-pound runner burns around 100 calories per mile at a moderate pace, while a 210-pound runner burns closer to 160 calories covering the same distance. The exact number shifts based on your weight, pace, sex, and body composition.
Body Weight Matters Most
Your body weight is the strongest predictor of how many calories you burn per mile. Heavier bodies require more energy to move the same distance, which is why a 210-pound person burns roughly 60% more calories per mile than a 130-pound person running at the same speed. A research team studying walkers and runners found that body mass and sex together predicted calorie expenditure with strong accuracy, confirming that weight alone gets you most of the way to a reliable estimate.
Here’s what a single mile looks like at a comfortable 10-minute pace (6 mph) across different body weights:
- 130 lbs: ~101 calories
- 155 lbs: ~121 calories
- 185 lbs: ~144 calories
- 210 lbs: ~164 calories
A simple formula can get you close to your own number. Multiply your weight in kilograms by 0.789, then subtract 7.6 if you’re female (or nothing if you’re male), and add 51. That gives you an estimate in calories per mile that accounts for both mass and sex.
How Pace Changes the Burn
This is where things get counterintuitive. At moderate running speeds, your pace doesn’t change per-mile calorie burn as much as you’d expect. A 155-pound person running a 12-minute mile burns about 123 calories, while the same person running a 9-minute mile burns around 117 calories. The difference is surprisingly small because a faster pace covers the distance in less time. You’re working harder per minute, but for fewer minutes.
The gap widens at genuinely fast speeds. Once you push past about 8 mph (a 7.5-minute mile), the energy cost per mile climbs noticeably. That same 155-pound runner at a 7-minute mile pace burns roughly 185 calories, and at a 6-minute mile pace, around 184 calories. At these intensities the body recruits more muscle fibers, breathing becomes far less efficient, and the metabolic cost per stride increases significantly.
Exercise scientists quantify this using MET values, which measure how hard an activity is compared to sitting still. Running at 6 mph registers a MET value of 9.3, meaning it demands about nine times the energy of rest. Bump the speed to 10 mph and the MET value jumps to 14.8. Those higher MET values at faster paces explain the steeper calorie cost, even though you’re spending less time on each mile.
Running vs. Walking the Same Mile
A common question is whether you burn the same calories walking a mile as running it. The answer is no. Running burns more total calories per mile because it involves a flight phase where both feet leave the ground, forcing your muscles to absorb and generate more force with every stride. Walking is biomechanically more efficient.
In a study comparing normal-weight women, overweight individuals, and male runners, the average energy cost of covering one mile (whether walking or running) came out to about 94 to 99 calories across groups. But this finding reflects the study’s specific mix of walking and running data, and the groups had very different body compositions. When researchers adjusted for lean body mass, the differences between groups largely disappeared, reinforcing that muscle is the engine driving calorie burn regardless of the activity.
As a general rule, running a mile burns about 20% to 30% more calories than walking the same mile at a brisk pace, assuming the same person does both.
Sex, Age, and Muscle Mass
Men typically burn more calories per mile than women, even at the same body weight. This comes down to body composition: men carry more muscle on average, and muscle tissue is metabolically expensive. The regression formula from the walking-and-running study subtracts about 7.6 calories per mile for women compared to men of equal weight, which reflects this difference in lean mass.
Age plays a quieter role. Resting metabolism drops by roughly 5 calories per day for each year you age, driven largely by the gradual loss of muscle tissue that starts in your 30s. This doesn’t dramatically change your per-mile burn in the short term, but a 50-year-old runner with less muscle mass will burn slightly fewer calories per mile than they did at 30, all else being equal. Strength training can offset much of this decline by preserving or building lean tissue.
Why Your Fitness Tracker May Be Wrong
If you’re relying on a treadmill display or a wrist-worn tracker for your calorie count, expect some error. Treadmill consoles tend to overestimate calorie burn by about 100 calories per 30 minutes of moderate exercise. They use generic formulas that can’t account for your fitness level, body composition, or running efficiency.
Wearable trackers aren’t much better. Research on popular fitness wearables found that even the most accurate device was off by an average of 27%, and the least accurate missed by 93%. Heart rate monitors built into these devices tend to be reasonably reliable, but the algorithms that convert heart rate data into calorie estimates introduce substantial error. If your watch says you burned 150 calories on a one-mile run, the real number could easily be 110 or 190.
For a more grounded estimate, use your body weight and the per-mile figures above rather than trusting any single device.
Practical Ways to Burn More Per Mile
If your goal is to maximize calorie burn from each mile you run, a few strategies actually move the needle. Running on hills or uneven terrain increases energy demand because your muscles work harder to propel you upward and stabilize on varied surfaces. A hilly mile can burn 10% to 15% more calories than a flat one.
Adding intervals, where you alternate between hard efforts and easy recovery, raises your average intensity for the run and keeps your metabolic rate elevated afterward. This post-exercise calorie burn is modest (typically an extra 30 to 50 calories over several hours) but adds up over consistent training.
Building more muscle through strength training increases your baseline energy expenditure, meaning every mile you run costs your body slightly more fuel. Over time, a runner who strength trains will burn more calories per mile than one who only runs, even if they weigh the same, because a greater proportion of their weight is metabolically active tissue.
