Insights for this run
How many calories does running burn?
Running burns roughly 0.75 calories per pound of body weight per mile (about 1 kcal per kg per km). A 160-lb runner burns about 124 calories per mile and 371 calories in 30 minutes at a 10-minute-mile pace. Weight and distance drive the total; pace mostly changes how quickly you get there, while hills and incline add substantially more.
How to use the running calories calculator
- Pick your units and enter body weight. Use your weight on the day of the run, including roughly what you carry (a hydration vest adds a kilo or two). Weight is the single biggest lever on calories burned running.
- Describe the run the way you remember it. Choose distance + time (most watches show this), pace + time, or distance + pace. The calculator derives the rest, so the 5K, 10K, half-marathon and marathon chips work in any mode.
- Add incline and surface. Set the treadmill grade or the average grade of a hilly route, and choose treadmill or outdoors. Outdoor running costs a little more because you push through still air.
- Read the result, then the range. The headline is the average of two independent methods; the range shows where they disagree. Use the net figure if you are deciding how much food to add back.
- Plan forward. Set runs per week for your weekly burn, and a target to see exactly how far and how long you would need to run at today’s pace.
The running calories formula we use
Most running calorie calculators online rely on one MET value from the 2011 Compendium. This one runs two independent, published methods on every input and shows you both — so you can see the estimate and its uncertainty instead of a single number that only looks precise.
Method 1 — 2024 Compendium MET method
Calories (kcal) = MET × body weight (kg) × duration (hours)
MET = interpolated from the 2024 Adult Compendium running codes 12028–12135 (6.5 METs at 4 mph up to 23.0 METs at 14 mph)
Uphill factor = 1 + 0.085·g − 0.0012·g² (g = grade %, 0–15)
The uphill factor is fitted to the Compendium’s own measured uphill codes 12255–12325 (for example, 6 mph rises from 9.3 to 13.3 METs at a 5% incline).
Method 2 — ACSM metabolic running equation
VO₂ (mL·kg⁻¹·min⁻¹) = 0.2 × speed + 0.9 × speed × grade + 3.5
speed in metres per minute · grade as a decimal (5% = 0.05) · outdoors adds 0.01 to grade
Calories (kcal) = VO₂ × weight (kg) × minutes ÷ 1000 × 5
The factor of 5 converts litres of oxygen to kilocalories (≈ 5 kcal per litre O₂ during mixed-fuel exercise). The outdoor 1% grade follows Jones & Doust’s finding that a 1% treadmill incline best reproduces the energy cost of running outside.
Net calories
Net kcal = gross kcal − the calories you would have burned at rest (1 MET, or 3.5 mL·kg⁻¹·min⁻¹) over the same time
The headline result is the mean of both methods; the range is the two methods’ individual answers. On flat ground the ACSM equation runs a little higher than the Compendium for most recreational paces, and the two converge on moderate inclines.
Worked example: a 30-minute 5K
A 160-lb (72.6 kg) runner finishes a 5K outdoors on flat ground in 30:00 — the calculator’s default inputs.
- Pace and speed: 5 km = 3.11 miles, so pace = 9:39 per mile and speed = 6.22 mph (166.8 m/min).
- Compendium: 6.22 mph sits between the 6.0 mph (9.3 METs) and 6.7 mph (10.5 METs) codes → 9.68 METs. 9.68 × 72.6 kg × 0.5 h = 351 kcal.
- ACSM: VO₂ = 0.2 × 166.8 + 0.9 × 166.8 × 0.01 + 3.5 = 38.37 mL/kg/min. 38.37 × 72.6 × 30 ÷ 1000 × 5 = 418 kcal.
- Result: (351 + 418) ÷ 2 = 384 calories burned (range 351–418), about 124 kcal per mile, and 347 kcal net of resting metabolism.
Calories burned running a mile by weight and pace
Look across any row and you’ll notice the per-mile number barely moves between a 12-minute and a 7-minute mile. That’s the most useful fact in running energetics: on flat ground you pay roughly the same energy to cover a mile at almost any comfortable pace — going faster mostly shortens the time it takes. Down the columns, burn rises in step with body weight.
Gross kcal per mile, outdoors, flat · blended estimate from both methods
| Body weight | 12:00 /mi | 10:00 /mi | 9:00 /mi | 8:00 /mi | 7:00 /mi |
|---|---|---|---|---|---|

Calories burned running for 30 minutes
Time is where pace does matter: run faster for the same 30 minutes and you cover more ground, so the total rises steeply. Use this table when your watch tells you the time of the session rather than the distance.
Gross kcal in 30 minutes, outdoors, flat
| Body weight | 5 mph (12:00/mi) | 6 mph (10:00/mi) | 7 mph (8:34/mi) | 8 mph (7:30/mi) |
|---|---|---|---|---|
| 120 lb | 244 | 278 | 324 | 361 |
| 140 lb | 285 | 325 | 378 | 421 |
| 160 lb | 326 | 371 | 432 | 481 |
| 180 lb | 367 | 417 | 486 | 541 |

| 240 lb | 489 | 556 | 648 | 721 |
Calories burned running a 5K, 10K, half marathon and marathon
Race distance totals at a steady 10:00-per-mile pace. A marathon is roughly 26 times the one-mile figure, which is why long-run fueling matters — the numbers below exceed the carbohydrate most people store in muscle and liver.
Gross kcal at 10:00 /mi, outdoors, flat
| Race (time at 10:00/mi) | 130 lb | 160 lb | 190 lb | 220 lb |
|---|---|---|---|---|
| 5K (31:04) | 312 | 384 | 456 | 528 |
| 10K (1:02:08) | 624 | 768 | 912 | 1,056 |
| Half marathon (2:11:06) | 1,317 | 1,621 | 1,924 | 2,228 |
| Marathon (4:22:11) | 2,633 | 3,241 | 3,849 | 4,457 |
Treadmill and incline: how grade changes calories burned running
Incline is the biggest multiplier you control. In the 2024 Compendium, running at 6 mph jumps from 9.3 to 13.3 METs on a 5% grade — about 43% more energy per minute. The ACSM equation predicts a smaller jump (about 20%) at 5%, but catches up at steeper grades. The table shows both, so you can see the real uncertainty.
160-lb runner, 6.0 mph (10:00 /mi), 30 minutes on a treadmill
| Grade | Compendium | ACSM | Blended | vs flat |
|---|---|---|---|---|
| 0% | 337 | 388 | 363 | — |
| 1% | 366 | 404 | 385 | +6% |
| 2% | 393 | 420 | 407 | +12% |
| 4% | 446 | 452 | 449 | +24% |
| 6% | 495 | 483 | 489 | +35% |
| 8% | 541 | 515 | 528 | +45% |
| 10% | 584 | 546 | 565 | +56% |
| 12% | 623 | 578 | 601 | +65% |
| 15% | 677 | 625 | 651 | +79% |
Treadmill vs outdoors on the flat: a 0% treadmill removes air resistance and the work of propelling yourself over the ground, so it under-reads the cost of outdoor running. If you want a treadmill session to match the road, set the incline to 1%. Downhill running is cheaper per minute at moderate grades, which is why this calculator limits grades to 0–15% uphill.
Running MET values by pace (2024 Compendium)
A MET (metabolic equivalent of task) is a multiple of the energy you burn sitting quietly; 1 MET is about 1 kcal per kilogram per hour. These are the flat-ground running values the calculator interpolates between. Any value of 6 METs or more is classed as vigorous activity in the U.S. Physical Activity Guidelines, so every running pace in this table counts toward the vigorous-minutes target.
| Speed (mph) | Pace (min/mi) | METs | Compendium code |
|---|---|---|---|
| 4.0–4.2 | 13:00 | 6.5 | 12028 |
| 4.3–4.8 | ~13:00–12:30 | 7.8 | 12029 |
| 5.0–5.2 | 12:00 | 8.5 | 12030 |

What actually changes how many calories you burn running
1. Body weight (the big one)
Running means lifting and moving your whole body with every stride, so energy cost scales almost directly with mass. A 200-lb runner burns about 25% more per mile than a 160-lb runner at the same pace. As you lose weight, your burn per mile falls too — re-enter your current weight every few weeks if you track it.
2. Distance and duration
For a given pace, calories grow linearly with distance. Double the miles, double the burn. That’s why “how many calories does running 3 miles burn” has a simple answer: roughly three times your per-mile figure.
3. Pace — less than most people think
Research going back to Margaria’s work in the 1960s shows the net energy cost of running per kilometre is close to constant across ordinary speeds. Faster pace raises calories per minute sharply, but calories per mile only modestly. Running faster burns more in a fixed lunch-hour slot; it does not dramatically change what a given 5K costs you.
4. Hills, incline and terrain
Gradient adds vertical work on top of horizontal work. Even a 3–5% average grade on a rolling route raises the burn noticeably. Soft sand, snow and technical trail also add cost, though they are harder to model with a single number — treat results for those surfaces as a floor.
5. Running economy and fitness
Experienced runners use slightly less oxygen at the same speed thanks to better mechanics. Formula-based estimates assume an average adult, so very economical runners may burn a little less than shown, and beginners a little more.
6. Running vs walking the same mile
For a 160-lb person, briskly walking a mile at 3.7 mph burns about 94 kcal gross (75 net) versus about 124 gross (111 net) for running it at 6 mph. Running the mile costs about 31% more gross energy and roughly 49% more net energy — and takes well under half the time. Our walking calorie calculator handles walking paces and incline properly, since running equations overestimate slow walking.
A pharmacist’s note on smartwatches, heart rate and fueling
Why your watch and this calculator disagree. Wrist-worn devices are good at heart rate and poor at energy expenditure. In a Stanford-led study of seven popular wearables, none estimated calories burned within an acceptable error range, with median errors from roughly 27% to 93%. This calculator doesn’t use heart rate at all — it works from the physical work of moving your body over a distance — so it’s often the steadier reference.
Medications that skew heart-rate-based numbers. Beta-blockers (such as metoprolol, atenolol or propranolol) blunt the heart-rate rise during exercise, so any tool that estimates calories from beats per minute will under-read your burn. Stimulant medications and high caffeine intake can push heart rate up and inflate those estimates. Pace-and-weight methods like the ones here are unaffected — a practical advantage if you take a rate-controlling medicine. Never change a dose to hit a training heart rate; ask your prescriber instead.
Eating back running calories. Use the net figure, not the gross one, because you would have burned the resting share anyway. For runs longer than about an hour, the ACSM, Academy of Nutrition and Dietetics and Dietitians of Canada joint position recommends roughly 30–60 g of carbohydrate per hour — a structured version of that is in our triathlon nutrition calculator.
Common mistakes when estimating calories burned running
- Counting gross calories as “extra” food. For a 30-minute run that’s roughly 35–45 kcal of resting metabolism double-counted; across a marathon block it adds up.
- Using goal weight instead of current weight. The calculator needs what you actually carried up the road today.
- Entering moving time but total distance (or the reverse). Use matching numbers. If you paused for traffic lights, use moving time with the same distance.
- Ignoring the route. A hilly 10K can cost noticeably more than a flat one at the same pace. Enter an average grade for honest numbers.
- Treating a single number as exact. Every method has about ±10–15% individual error. Watch the range and your trend over weeks, not a single run.
- Assuming faster always means “more fat burned”. Total energy matters more than the fuel mix for body-composition goals, and easy miles you can repeat beat hard miles you can’t.

Running calories calculator FAQs
How many calories does running a mile burn?
Running a mile burns about 0.75 calories per pound of body weight. At a 10-minute-mile pace on flat ground, that is roughly 100 calories for a 130-lb runner, 124 for 160 lb, 147 for 190 lb and 170 for 220 lb. Pace changes the per-mile figure only slightly; hills raise it considerably.
How many calories does a 5K run burn?
A 5K (3.1 miles) at a 10-minute-mile pace burns about 312 calories at 130 lb, 384 at 160 lb, 456 at 190 lb and 528 at 220 lb. A faster 5K takes less time but costs almost the same total energy, because calories per mile stay fairly constant across normal running paces.
How many calories do I burn running for 30 minutes?
For a 160-lb runner, 30 minutes burns about 326 calories at 5 mph (12:00/mile), 371 at 6 mph, 432 at 7 mph and 481 at 8 mph. Over a fixed time, running faster burns noticeably more because you cover more distance.
Does running faster burn more calories?
Per minute, yes — a lot more. Per mile, no. A 160-lb runner burns about 130 calories covering a mile at 12:00 pace and about 118 at 7:00 pace, because faster running is slightly more economical per mile. If you have a fixed amount of time, run faster; if you have a fixed distance, pace matters much less than most people think.
Do you burn fewer calories running on a treadmill?
Slightly, on a flat belt. A 0% treadmill removes air resistance, so it under-reads outdoor energy cost by a few percent at typical speeds — about 16 calories over 30 minutes at 6 mph for a 160-lb runner. Setting the treadmill to a 1% incline closely matches running outdoors.
How much does incline increase calories burned running?
A lot. In the 2024 Compendium, running at 6 mph rises from 9.3 to 13.3 METs on a 5% grade. Averaging both methods, a 160-lb runner burns about 363 calories in 30 minutes on a flat treadmill and about 469 at 5% — roughly 29% more.
What is the difference between gross and net calories burned running?
Gross calories are everything you burned during the run, including the energy your body would have used anyway at rest. Net calories subtract that resting share (about 1 kcal per kg per hour). Use net calories when deciding how much extra food a run has earned.
How accurate is a running calories calculator?
A good formula-based running calorie calculator is typically within about 10–15% for an average adult, because it relies on measured oxygen-cost data. Individual running economy, fitness and body composition move the true number up or down. This calculator shows the range between two published methods so you can see that uncertainty.
Are smartwatch calorie estimates accurate for running?
Not very. A Stanford-led study of seven wrist-worn devices found none measured energy expenditure within an acceptable error range, with median errors of roughly 27% to 93%. Watches are much better at heart rate and distance than calories, so a pace-and-weight calculator is often a steadier reference.
Do heavier people burn more calories running?
Yes. Calories burned running scale almost directly with body weight, because you move your whole mass with every stride. A 200-lb runner burns about 25% more per mile than a 160-lb runner at the same pace, and your per-mile burn falls as you lose weight.
Should I eat back the calories I burn running?
Eat back net calories, not gross, and only as much as your goal allows — a weight-loss plan intentionally leaves part of the burn uncovered. For runs over about an hour, sports nutrition guidance recommends roughly 30–60 g of carbohydrate per hour to sustain performance.
How many calories does running a marathon burn?
A marathon at a 10-minute-mile pace (about 4 hours 22 minutes) burns roughly 3,241 calories for a 160-lb runner, and about 2,633 to 4,457 calories for runners between 130 and 220 lb. That is more energy than the body stores as carbohydrate, which is why marathon fueling matters.
