How many calories does running burn?

A general estimate is roughly 100 calories per mile for a 155 lb person, but actual burn depends on weight, pace, and terrain. The formula: Calories = MET × weight(kg) × time(hours). Running at 6 mph (10 min/mile) has a MET of 9.8. A 180 lb person burns ~140 calories per mile at that pace.

Does running faster burn more calories?

Yes. Faster running has a higher MET value: 6 mph (MET 9.8) vs 8 mph (MET 11.8) vs 10 mph (MET 14.5). However, per mile the difference is smaller than per minute. Running faster burns significantly more calories per minute but only somewhat more per mile.

Do heavier people burn more calories running?

Yes. Calorie burn is directly proportional to body weight. A 200 lb person burns roughly 30% more calories than a 150 lb person running the same distance at the same pace. This is because more energy is required to move a heavier body.

How many calories to lose 1 pound?

Approximately 3,500 calories equals one pound of body fat. Running 3-4 miles per day (at ~100 cal/mile) creates a ~300-400 calorie deficit, which combined with dietary adjustments can lead to roughly 1 pound of fat loss per week.

Walking vs running calorie burn?

Per mile, running burns about 20-30% more calories than walking due to higher intensity and afterburn effect (EPOC). Per minute, running burns 2-3x more calories. For time-efficient calorie burning, running wins. For joint-friendly exercise at any fitness level, walking is excellent.

What is EPOC (afterburn effect)?

Excess Post-Exercise Oxygen Consumption means your body continues burning extra calories after running to restore oxygen levels, repair muscles, and replenish energy stores. EPOC adds roughly 5-15% extra calories on top of exercise calories, more for intense runs.

Running Calorie Burn: The Science of How Running Burns Energy

Running is one of the most efficient calorie-burning exercises available. How many calories you burn depends on a precise interaction between your body weight, running speed, terrain, and duration. Understanding the science helps you plan training for weight loss, estimate fueling needs for long runs, and appreciate why running is such an effective component of any fitness program.

The MET-Based Calorie Formula

Calories = MET × Weight(kg) × Time(hours)

MET values by speed (ACSM Compendium):
Walking 3.5 mph = 4.3 MET
Jogging 5 mph = 8.3 MET
Running 6 mph (10:00/mi) = 9.8 MET
Running 7 mph (8:34/mi) = 11.0 MET
Running 8 mph (7:30/mi) = 11.8 MET
Running 9 mph (6:40/mi) = 12.8 MET
Running 10 mph (6:00/mi) = 14.5 MET

Example: 175 lbs (79.4 kg) at 6 mph for 30 min
Cal = 9.8 × 79.4 × 0.5 = 389 calories

Weight and Pace: The Two Biggest Factors

Body weight has a linear relationship with calorie burn — a 200 lb runner burns roughly 33% more than a 150 lb runner covering the same distance at the same pace. This is simply because more energy is required to move more mass. Running pace affects burn rate per minute dramatically (faster = more calories per minute) but has a smaller effect per mile. The practical implication: if time is limited, run faster; if you can run longer, distance matters more than speed for total burn.

Maximizing Calorie Burn

Add hills or trail running for 10-20% more calories than flat road. Incorporate interval training (alternating fast/slow segments) for higher EPOC afterburn. Consistency beats intensity — five 30-minute runs burn more than one 90-minute run and two rest days. Strength training builds muscle which increases base metabolic rate, amplifying running's calorie burn over time.

EPOC: The Afterburn Effect

After running, your body continues burning extra calories through Excess Post-Exercise Oxygen Consumption (EPOC). This afterburn covers oxygen debt repayment, muscle repair, glycogen restoration, and body temperature regulation. EPOC typically adds 5-15% extra calories on top of exercise calories. Higher-intensity running produces greater EPOC. A hard tempo run or interval session can elevate metabolism for 12-24 hours afterward, while an easy jog produces minimal EPOC.

Common Calorie Counting Mistakes

Fitness trackers and treadmills often overestimate calorie burn by 15-30%. The "100 calories per mile" rule is only rough — actual burn varies 20%+ based on weight and pace. Do not eat back all exercise calories when trying to lose weight — estimates are imprecise, so eat back only 50-75%. Running does not give you license to eat unlimited amounts — it is easy to out-eat your run with one large meal.

Running for Weight Loss

One pound of fat equals approximately 3,500 calories. Running 3 miles daily at 10:00/mile burns roughly 350-400 calories. Combined with a 200-300 calorie dietary reduction, this creates a 500-700 calorie daily deficit — translating to approximately 1-1.5 pounds of fat loss per week, which is the safe and sustainable rate recommended by health professionals. Preserve muscle during weight loss by maintaining adequate protein intake (0.8-1.0g per pound of body weight) and including some resistance training alongside running.
