How many calories does running burn?
The most accurate way to estimate calories burned running is the MET (Metabolic Equivalent of Task) formula: Calories = MET × 3.5 × weight (kg) / 200 × time (minutes). MET values for running range from 6.0 (slow jog at 6.4 km/h) to 23.0 (elite sprint pace at 22.5 km/h), drawn from the 2011 Compendium of Physical Activities.
A simpler rule of thumb: running burns approximately 1.0–1.1 kcal per kg of body weight per kilometre (about 0.75 kcal/lb/mile). A 75 kg runner covering 10 km burns roughly 750–800 kcal at most everyday paces — because going faster finishes the distance sooner, using roughly the same total energy per unit distance.
Calories burned running by distance and weight
Estimated calories at a moderate 6:00/km (9:40/mile) pace using the MET formula:
| Distance | 60 kg / 132 lb | 75 kg / 165 lb | 90 kg / 198 lb |
|---|---|---|---|
| 1 mile (1.6 km) | ~102 kcal | ~128 kcal | ~153 kcal |
| 5K (3.1 miles) | ~317 kcal | ~396 kcal | ~475 kcal |
| 10K (6.2 miles) | ~634 kcal | ~792 kcal | ~951 kcal |
| Half marathon (13.1 mi) | ~1,337 kcal | ~1,672 kcal | ~2,006 kcal |
| Marathon (26.2 mi) | ~2,675 kcal | ~3,344 kcal | ~4,012 kcal |
Estimates based on MET 10.1 (6:00/km pace, 10 km/h). Results vary by speed, terrain, and individual metabolism. Use the calculator for exact figures.
Calories burned running vs jogging: what is the difference?
Jogging is generally defined as running below 9.6 km/h (6 mph or 10:00/mile pace). Running starts above that threshold. Because distance-based calorie burn is roughly constant regardless of pace, the main difference is time:
| Activity | Speed | MET | Kcal/hr (75 kg) |
|---|---|---|---|
| Slow jog | 6.4 km/h (4 mph) | 6.0 | ~473 |
| Jogging | 8.0 km/h (5 mph) | 8.3 | ~654 |
| Easy run | 9.7 km/h (6 mph) | 9.8 | ~772 |
| Moderate run | 12.9 km/h (8 mph) | 11.8 | ~929 |
| Fast run | 16.1 km/h (10 mph) | 14.5 | ~1,142 |
| Race pace | 19.3 km/h (12 mph) | 19.0 | ~1,496 |
Jogging burns fewer calories per hour but is sustainable for longer, so total calories can end up similar. For a 75 kg person covering the same 5 km, the calories burned stay close regardless of pace: about 375 kcal at 5:00/km, 396 kcal at 6:00/km and 409 kcal at 7:30/km.
Does elevation affect calories burned running?
Yes. Running uphill significantly increases calorie expenditure. The additional energy cost of climbing elevation is approximately 0.00955 kcal per kilogram of body weight per metre of elevation gain. For a 75 kg runner climbing 100 metres:
Extra calories = 100 m × 75 kg × 0.00955 = ~72 additional kcal.
A hilly 10K with 200 m of elevation gain burns roughly 150 kcal more than a flat 10K at the same weight. The calculator includes an optional elevation gain field to account for this. Running downhill partially offsets uphill cost, but the calculator uses net elevation gain as a conservative estimate.
What is fat burned when running?
The calculator outputs fat burned in grams alongside calories. The formula: 1 kg of body fat ≈ 7,700 kcal (this accounts for the water and protein content of adipose tissue, so it is lower than the pure fat energy value of 9 kcal/g).
Fat burned (g) = calories ÷ 7.7
A 75 kg person running 10 km and burning 750 kcal burns approximately 97 g of fat. Keep in mind this is an estimate of total fat oxidised during the run — your body burns a mix of carbohydrates and fat depending on intensity. At lower intensities (easy jog), fat provides a larger proportion of energy. At higher intensities (fast run), carbohydrates dominate.
Running calories for weight loss: how much do you need to run?
A calorie deficit of 7,700 kcal is required to lose 1 kg of body fat. Running is one of the most efficient calorie-burning exercises, but the numbers are more modest than most people expect:
- To burn 500 kcal: A 75 kg person needs to run approximately 6.3 km (3.9 miles). At a 6:00/km pace, that is about 38 minutes.
- To lose 0.5 kg of fat: You need to create a 3,850 kcal deficit through running alone — roughly 49 km (30 miles) for a 75 kg person, or about 6–7 hours of running.
- To lose 1 kg of fat: Approximately 97 km (60 miles) of running for a 75 kg person — more realistic combined with a dietary deficit of 300–500 kcal/day.
- Realistic weekly target: Running 30–40 km per week (3–5 runs) burns about 2,400–3,200 kcal for a 75 kg person, equivalent to 0.3–0.4 kg of fat per week combined with a modest dietary deficit.
Factors that affect calories burned running
| Factor | Effect on calorie burn | Impact |
|---|---|---|
| Body weight | Heavier runners burn more calories for the same distance | High |
| Distance | Linear relationship — double the distance, double the calories | High |
| Speed / pace | Minimal effect per km; large effect per hour | Moderate |
| Elevation gain | +0.00955 kcal per kg per metre climbed | Moderate–High |
| Running surface | Soft surfaces (trail, sand) increase effort by 10–30% | Moderate |
| Air temperature | Cold weather slightly increases calorie burn (body heats itself) | Low |
| Fitness level | Fitter runners are more efficient — burn slightly fewer kcal/km | Low |
| Treadmill vs outdoor | Treadmill is slightly easier; set 1–2% incline to compensate | Low |
Frequently asked questions
How many calories does running burn per mile?
Running burns approximately 100–155 calories per mile depending on body weight. At a 6:00/km pace, a 60 kg (132 lb) runner burns about 102 kcal/mile, a 75 kg (165 lb) runner about 128 kcal/mile, and a 90 kg (198 lb) runner about 153 kcal/mile. The commonly cited figure of 100 calories per mile fits a runner of about 60 kg (130 lb).
How many calories does running burn per km?
Running burns approximately 60–95 calories per kilometre depending on body weight. At a 6:00/km pace, a 60 kg person burns about 63 kcal/km, a 75 kg person about 79 kcal/km, and a 90 kg person about 95 kcal/km. The rule of thumb is 1.0–1.1 kcal per kg per km.
How many calories burned running 5K?
Running 5K burns approximately 320–475 calories depending on body weight. At a 6:00/km pace, a 60 kg person burns about 317 kcal, a 75 kg person about 396 kcal, and a 90 kg person about 475 kcal. Pace has minimal effect on total calories for the same distance at moderate speeds.
How many calories burned running a marathon?
Running a full marathon (42.2 km / 26.2 miles) burns approximately 2,700–4,000 calories depending on body weight. At a 6:00/km pace, a 60 kg runner burns about 2,675 kcal, a 75 kg runner about 3,344 kcal, and a 90 kg runner about 4,012 kcal. This is why marathon runners carb-load — they cannot carry enough glycogen to run the full distance without fuelling.
Does running faster burn more calories?
Running faster burns more calories per hour but roughly the same calories per kilometre. If you run 10 km in 50 minutes or 10 km in 40 minutes, total calorie burn is similar. However, at very high speeds (above 16 km/h), the metabolic cost per km does increase slightly due to the mechanical demands of fast running.
How many calories do you burn jogging for 30 minutes?
Jogging for 30 minutes at 8 km/h (5 mph) burns approximately 261 kcal for a 60 kg person, 327 kcal for a 75 kg person, and 392 kcal for a 90 kg person. At this pace you cover roughly 4 km in 30 minutes.
Is running on a treadmill the same calories as running outside?
Treadmill running is slightly easier than outdoor running because there is no wind resistance and the belt assists leg turnover. The calorie difference is small (5–10%). Setting the treadmill to 1–2% incline closely matches the metabolic cost of outdoor flat running. Hills, soft surfaces, and headwinds all increase calorie burn outdoors.
How much do I need to run to burn 500 calories?
To burn 500 kcal running, a 60 kg person needs to run approximately 7.9 km (4.9 miles), a 75 kg person about 6.3 km (3.9 miles), and a 90 kg person about 5.3 km (3.3 miles). At a 6:00/km pace, this takes about 32–48 minutes depending on your weight.
Does elevation gain affect calories burned running?
Yes. Each metre of elevation gain adds approximately 0.00955 kcal per kg of body weight in extra calorie burn. A 75 kg runner climbing 200 metres of elevation burns an extra 143 kcal. The calculator includes an elevation field to account for this — useful for trail runs and hill repeats.
How many calories does running burn compared to cycling or swimming?
Running burns more calories per hour than cycling at the same perceived effort, because running supports your full body weight. Running at 10 km/h burns about 790 kcal/hr for a 75 kg person, which makes it one of the highest-calorie activities per unit of time. Vigorous cycling and lap swimming can come close; use the bike and swimming calculators to compare at your own speed.
