Run details
Estimates only, based on standardized MET values from the 2024 Compendium of Physical Activities. Real-world burn varies by about 10 to 15% with incline, terrain, wind, fitness, and running economy, none of which are modeled here. The fat-gram figure is a rough split and shifts with effort.
How the running calorie calculator works
The math behind every credible running calorie estimate is the MET formula: calories equal MET multiplied by your weight in kilograms multiplied by your time in hours. MET stands for metabolic equivalent, a unit that describes how hard an activity is relative to sitting still. One MET is roughly the energy you burn at rest, so a 10 MET run burns about ten times that.
This tool pulls MET values for running straight from the 2024 Adult Compendium of Physical Activities, matched to your pace. A slow jog sits near 6 MET, an easy run lands around 9 to 10 MET, and a hard tempo effort climbs past 12 MET. Your weight and your time on feet do most of the work in the formula, which is why a longer run at a comfortable pace can out-burn a short fast one.
How many calories you burn running by distance
If you want quick reference points, here is the rough range for a typical runner, with heavier runners landing toward the top of each band:
1 mile: about 80 to 140 cal. 5K (3.1 miles): about 300 to 450 cal. 10K (6.2 miles): about 600 to 900 cal. Half marathon (13.1 miles): about 1,300 to 1,900 cal. Marathon (26.2 miles): about 2,600 to 3,800 cal.
Body weight shifts these numbers more than anything else. Add 40 or 50 lb and every figure climbs, because the formula scales straight off your mass in kilograms. Use the distance presets above to drop in a 5K, 10K, half, or full marathon and see your own total.
What affects how many calories you burn running
Five things move the number. Body weight comes first, since it multiplies directly in the formula. Duration is next: more time on feet means more total calories, full stop. Pace and intensity raise the per-minute rate, though the effect on total burn is smaller than you might guess, because faster runs finish sooner. Incline and terrain add work that a flat-ground estimate misses, so hills push the real number up. Fitness and running economy nudge it the other way, since a trained runner moves more efficiently.
So the practical point is simple: for total calories, how far you run matters more than how fast. If your goal is heart-rate-based training rather than raw burn, the heart rate zone calculator is a better fit. To plan hydration around longer runs, check the water intake calculator.
Using calorie burn in a 75-day challenge
Most 75-day challenges build in a daily workout or an outdoor workout, and running checks that box cleanly. Logging your runs gives you a real number to work with instead of a guess, which helps when you are managing intake at the same time. Pair this calculator with the calorie deficit calculator for a daily target, the TDEE calculator for your maintenance baseline, and the macro calculator to split out protein, carbs, and fat.
If you want a simple way to mark each run done and keep a streak across the full challenge, Reset75 handles checklists, progress photos, and stats with no account required. Treat the calorie figure as one input among several, not a target to chase, and let consistency do the heavy lifting.
Frequently Asked Questions
Common questions about calories burned running calculator
How many calories do you burn running a 5K?
A 5K (3.1 miles) burns roughly 300 to 450 cal for most people, depending on body weight and pace. A 155 lb runner at a 10:00/mi pace burns about 360 cal. Heavier runners burn more over the same distance because moving more mass costs more energy. Enter your own numbers above for a personalized estimate.
How many calories do you burn per mile running?
A common rule of thumb is about 100 cal per mile, but real numbers run from roughly 80 cal for a light runner to 140+ cal for a heavier one. Body weight is the biggest factor. The per-mile figure stays fairly steady across paces, which is why total distance matters more than speed for overall burn.
Does running faster burn more calories?
Running faster burns more calories per minute because the MET (intensity) value climbs with speed. Over the same distance, though, the gap is smaller than you might think, since a faster run also finishes sooner. For total calories, how far you run usually matters more than how fast. To train by effort instead, try the heart rate zone calculator.
How does body weight affect calories burned running?
Body weight is the biggest factor in calorie burn while running. The core formula multiplies your weight in kilograms directly, so a 200 lb runner burns roughly 30% more than a 155 lb runner over the same distance and pace. This calculator converts your weight to kilograms internally before applying the MET formula.
How many calories does running 10K or a half marathon burn?
A 10K (6.2 miles) burns roughly 600 to 900 cal, and a half marathon (13.1 miles) burns roughly 1,300 to 1,900 cal, scaling with body weight. Use these as ballpark figures. Enter your weight and pace above for a tailored estimate, then pair the burn with the TDEE calculator to see how it fits your day.
Is this running calorie calculator accurate?
It uses MET values from the 2024 Adult Compendium of Physical Activities, the same standardized lab estimates most reputable calculators rely on. Treat the result as a solid estimate, good to within about 10 to 15%. It does not account for incline, wind, terrain, running economy, or fitness level, all of which shift the real number.
Does running on an incline or treadmill change calories burned?
Yes. Running uphill or at a treadmill incline raises calorie burn because you are doing extra work against gravity. A flat treadmill without incline can actually read slightly lower than running outdoors, since the belt assists leg turnover and there is no air resistance. This calculator assumes flat, level running, so add a margin for hills.
How many calories should I burn running to lose weight?
Weight loss comes from a calorie deficit, not from any single workout total. A few hundred calories burned per run adds up over a week, but diet does most of the work. Use the calorie deficit calculator to set a daily target, then log your runs as part of your overall burn.
