Walking 2 miles burns roughly 130 to 270 calories, depending mostly on your body weight. Running the same distance bumps that up to about 180 to 370 calories. The exact number shifts based on your pace, the terrain, and whether you’re moving uphill or on flat ground, but weight is the single biggest factor.
Walking 2 Miles: Calories by Body Weight
At a typical walking pace of 2.5 to 3.5 mph (about a 17- to 24-minute mile), here’s what 2 miles costs your body in calories:
- 120 lbs: 128 calories
- 140 lbs: 149 calories
- 160 lbs: 170 calories
- 180 lbs: 191 calories
- 200 lbs: 213 calories
- 220 lbs: 234 calories
- 250 lbs: 266 calories
The pattern is straightforward: for every additional 20 pounds of body weight, you burn roughly 20 more calories over the same 2-mile distance. A heavier body requires more energy to move, which is why weight matters more than almost any other variable during a walk.
Running 2 Miles: Calories by Body Weight
Running increases the calorie cost per mile because your muscles work harder to propel your body off the ground with each stride. Over 2 miles, the numbers look noticeably different from walking:
- 120 lbs: 180 to 220 calories
- 150 lbs: 225 to 275 calories
- 180 lbs: 270 to 330 calories
- 200 lbs: 300 to 370 calories
The ranges reflect differences in pace. A 10-minute mile (6 mph) sits at the lower end, while an 8-minute mile (7.5 mph) pushes toward the higher end. That said, the effect of running faster is modest compared to the effect of weighing more. A 200-pound person jogging slowly will burn more than a 120-pound person sprinting.
Why Running Burns More Than Walking
Exercise intensity is measured in METs, or metabolic equivalents. One MET is the energy your body uses while sitting still. Walking at a normal pace comes in around 3.3 METs, meaning it burns about 3.3 times your resting energy expenditure. Running at 6 mph jumps to 9.3 METs, and an 8 mph pace hits 12.0 METs.
But there’s a catch when comparing the two over the same distance. Walking 2 miles takes roughly 40 minutes, while running 2 miles at 6 mph takes about 20 minutes. So even though running has a much higher MET value per minute, you spend half as long doing it. The net result is that running 2 miles burns roughly 40% to 70% more total calories than walking 2 miles, not three times more as the MET numbers might suggest.
How Incline Changes the Math
Walking or running uphill adds a significant calorie premium. For every 1% increase in grade, a 150-pound person burns about 10 extra calories per mile, which works out to roughly a 12% bump per percentage point of incline. Over 2 miles at a 5% treadmill incline, that same person would burn close to 100 additional calories compared to walking on flat ground.
This is one reason incline treadmill walking has become popular. You can get a calorie burn comparable to jogging while keeping the lower impact of walking. A 150-pound person walking 2 miles at a brisk pace on a 10% incline could approach 300 calories, putting it in the same range as a flat-ground run.
The Afterburn Effect
Your body continues burning calories at an elevated rate after you stop exercising, a phenomenon called excess post-exercise oxygen consumption (EPOC). Your heart rate is still up, your muscles are repairing, and your core temperature is returning to normal. All of that costs energy.
For a moderate effort like a 2-mile run, EPOC typically adds 6% to 15% on top of the calories you burned during the workout itself. If your run burned 300 calories, you might burn an extra 18 to 45 calories over the next several hours without doing anything. It’s a real effect, but not a dramatic one at this distance. EPOC becomes more significant after longer or higher-intensity sessions.
What Matters Most for Calorie Burn
If your goal is to maximize calories over 2 miles, these are the variables that matter, ranked by impact:
- Body weight: The single largest factor. A person who weighs 250 pounds burns roughly double what a 120-pound person burns over the same distance.
- Walking vs. running: Running the distance instead of walking it adds 40% to 70% more calories.
- Incline: Each 1% of grade adds about 12% more calories per mile. Even a moderate hill makes a meaningful difference.
- Pace (within the same activity): Running faster does burn slightly more per mile, but the difference between a 10-minute mile and an 8-minute mile is smaller than most people assume.
One detail worth keeping in mind: most calorie calculators, fitness watches included, report total calories, which includes the calories you would have burned anyway just by being alive during that time. The “net” calories, the extra energy your body spent because of the exercise, are somewhat lower. For a 2-mile walk that takes 40 minutes, subtract roughly 50 to 80 calories (depending on your weight) to get the net figure. For a 20-minute run, subtract about 25 to 40. This matters if you’re trying to create a precise calorie deficit, but for general fitness tracking, total calories are the standard people use.
