Most people burn between 80 and 140 calories running a mile at an easy pace. The exact number depends primarily on your body weight, with pace and fitness level playing smaller but real roles. A 150-pound runner burns roughly 110 to 120 calories per mile, while a 200-pound runner burns closer to 150 to 170.
Calories Burned Per Mile by Body Weight
Body weight is the single biggest factor in how many calories you burn running a mile. A heavier body requires more energy to move the same distance. Here’s what the numbers look like across a range of weights and common paces:
- 120 pounds: 86 to 144 calories per mile, depending on speed
- 150 pounds: 107 to 180 calories per mile
- 180 pounds: 129 to 216 calories per mile
- 210 pounds: 150 to 252 calories per mile
At a comfortable 10-minute mile (6 mph), a 150-pound person burns about 117 calories per mile. At a faster 7.5-minute mile (8 mph), that same person burns roughly 166 calories. The jump is real, but it’s not as dramatic as you might expect. Running faster does burn more calories per mile, but the difference between a jog and a sprint over the same distance is only about 30 to 50%.
Why Speed Changes the Burn (But Not by Much)
Running faster increases your calorie burn per mile because your body works harder mechanically. Your muscles generate more force, your arms pump more aggressively, and you bounce higher off the ground with each stride. Exercise scientists measure this using MET values, which represent how much energy an activity demands compared to sitting still. Running at 5 mph has a MET value of 8.5, meaning it costs 8.5 times more energy than rest. At 7 mph, that rises to 11.0. At 10 mph, it reaches 14.8.
But here’s the nuance: you spend less time running when you go faster. A 10-mph mile takes 6 minutes; a 5-mph mile takes 12. So while the per-minute burn nearly doubles, the per-mile burn increases more modestly. For a 150-pound person, the difference between a slow jog and a near-sprint is roughly 60 to 70 extra calories per mile. That matters over weeks of training, but it means you shouldn’t feel pressure to run fast just for calorie purposes. Simply covering the distance gets you most of the benefit.
The “Net” Calories You Actually Burned
Every calorie estimate you see for running includes the calories your body would have burned anyway just being alive. Your heart beats, your lungs expand, your cells maintain themselves. That baseline burn is roughly 1 to 1.5 calories per minute for most adults. Over a 10-minute mile, that’s 10 to 15 calories you would have spent sitting on your couch.
Research comparing gross and net calorie costs of running found that men burn about 1.57 calories per kilogram of body weight per mile in total, but the net cost (subtracting resting metabolism) drops to about 1.43 calories per kilogram. For women, the gross cost was 1.73 calories per kilogram, with a net cost of 1.53. In practical terms, the net calorie burn of running a mile is roughly 8 to 12% lower than what most calculators show you. For a 150-pound runner, that means about 10 to 15 fewer “real” calories per mile than the headline number.
This matters most if you’re running to lose weight and eating back your exercise calories. A running app might say you burned 120 calories, but the additional energy you spent beyond what your body needed anyway is closer to 105.
A Quick Formula to Estimate Your Burn
If you want a rough estimate without a chart, a reliable rule of thumb is about 0.75 calories per pound of body weight per mile at a moderate pace. Multiply your weight in pounds by 0.75, and you’ll land close to your net calorie burn for one mile of running. A 160-pound runner gets 120 calories. A 130-pound runner gets about 98.
For a more precise number, the standard formula used in exercise science calculates oxygen consumption based on speed and then converts that to calories. But for everyday tracking, the per-pound shortcut gets you within 10% of lab-measured values, which is more accurate than most fitness trackers anyway.
Running Burns About 30% More Than Walking
A common question behind this search is whether running a mile burns more calories than walking a mile. The answer is yes, by roughly 30%. Cleveland Clinic puts the differential at about that level, and the research data supports it. Walking a mile costs about 1.08 to 1.15 calories per kilogram of body weight, while running costs 1.57 to 1.73 calories per kilogram.
The reason is biomechanical. When you run, both feet leave the ground with every stride, and your body has to absorb and generate impact forces that walking doesn’t require. Your muscles work harder to stabilize your joints, propel you forward, and decelerate on landing. All of that costs extra energy. For a 150-pound person, walking a mile burns about 75 to 80 calories, while running the same mile burns 110 to 120. Over time, that 30% gap adds up considerably.
Fitness Level Affects Efficiency
Two runners who weigh the same and run at the same pace won’t necessarily burn identical calories. Experienced runners develop better “running economy,” meaning their bodies waste less energy on unnecessary movement. Research in exercise physiology has shown that in highly trained runners, the calf muscles alone account for about 25% of the total energy cost of each stride. In less trained runners, that proportion rises to nearly 40%, because their muscles contract less efficiently and require more energy to produce the same force.
This means a beginner might burn 10 to 15% more calories per mile than someone who has been running for years, even at identical weight and pace. That’s actually good news if you’re new to running for weight management. But it also means your calorie burn per mile will gradually decrease as you get fitter, which is one reason weight loss from running tends to plateau over months of consistent training.
Why Your Fitness Tracker May Be Wrong
If you rely on a smartwatch or fitness band to count your running calories, take the number with a grain of salt. A Stanford study that tested seven popular wearables, including the Apple Watch, Fitbit Surge, and Samsung Gear S2, found that none of them measured calorie expenditure accurately. The best device was off by an average of 27%. The worst missed by 93%. Interestingly, these same devices measured heart rate with less than 5% error, which means the hardware works fine but the algorithms that convert heart rate into calories are unreliable.
For a 150-pound runner burning roughly 115 calories per mile, a 27% error means your watch might report anywhere from 84 to 146 calories. That’s a wide enough range to throw off your nutrition math if you’re eating based on exercise calories. A simple body-weight calculation (your weight in pounds times 0.75) is likely just as accurate, if not more so, than what your wrist tells you.
