Walking 5 miles burns roughly 350 to 600 calories for most people, with your body weight being the single biggest factor in where you fall in that range. A 180-pound person walking at a moderate pace burns about 96 calories per mile, putting their 5-mile total around 480 calories. A lighter person burns less, a heavier person burns more, and your speed and terrain shift the number further.
How Body Weight Changes the Math
Calorie burn during walking is almost directly proportional to how much you weigh. Your muscles have to move your entire body forward with every step, so more mass means more work. The standard formula uses something called a MET value (a measure of how hard your body is working compared to sitting still) multiplied by your weight and the time spent walking.
For a moderate walking pace of about 3 mph, the MET value is 3.3, meaning you’re burning 3.3 times as many calories as you would sitting on the couch. At a brisk 4 mph pace, that jumps to 5.0. Here’s what that looks like over 5 miles at a moderate pace:
- 130 pounds: approximately 350 calories
- 155 pounds: approximately 415 calories
- 180 pounds: approximately 480 calories
- 205 pounds: approximately 550 calories
These numbers use the standard MET formula: calories per minute = (MET × body weight in kg × 3.5) ÷ 200. At 3 mph, 5 miles takes about 100 minutes, which makes the multiplication straightforward. If you walk faster at 4 mph, you finish in 75 minutes but burn calories at a higher rate per minute, so your total ends up similar or slightly higher.
Speed Matters Less Than You’d Think
This surprises most people: walking speed has a relatively small effect on total calories burned over the same distance. A 180-pound person burns about 96 calories per mile at a moderate pace and roughly 102 calories per mile at a brisk pace. Over 5 miles, that’s only about a 30-calorie difference. You finish sooner when you walk faster, but each mile costs your body nearly the same amount of energy.
The reason is that walking is mechanically efficient. Your body essentially swings each leg forward like a pendulum, catching your momentum with each step. Speeding up slightly doesn’t dramatically change this movement pattern. The real efficiency shift happens at very high walking speeds, around 5 mph, where the gait becomes awkward and inefficient. At that point, it actually takes more energy to walk than to run at the same speed, which is why your body naturally wants to break into a jog.
Walking vs. Running the Same Distance
Running 5 miles burns considerably more calories than walking 5 miles, even though the distance is identical. The main reason is vertical movement. When you run, your body bounces up and down much more with each stride. Your leg muscles generate extra force to propel you upward, and that energy doesn’t move you any closer to your destination. It’s essentially wasted as heat.
There’s also an afterburn effect. After finishing a run, your body continues burning calories at an elevated rate for several minutes as it cools down and replenishes energy stores. This post-exercise calorie burn after running is more than double what it is after walking the same distance, because of the difference in intensity. For a rough comparison, running 5 miles typically burns 30% to 50% more total calories than walking the same route.
Hills Add Up Quickly
Terrain is one of the easiest ways to increase your calorie burn without changing your distance or speed. Walking uphill forces your muscles to work against gravity, and the effect is dramatic. For a 150-pound person, every 1% increase in grade adds about 10 extra calories per mile, which works out to roughly a 12% increase in energy expenditure per percent of incline.
Over 5 miles, that compounds fast. A gentle 3% grade, the kind you might barely notice on a neighborhood street, would add roughly 150 extra calories to the walk for a 150-pound person. A steeper 5% grade would push the bonus past 250 extra calories. If you’re walking on a treadmill and want more burn without walking longer, incline is far more effective than adding speed.
Gross vs. Net Calories
One detail worth knowing: the numbers above are gross calories, meaning they include the energy your body would have burned anyway just by being alive during that time. Your body burns calories around the clock to keep your heart beating, lungs breathing, and organs functioning. If you want to know how many extra calories the walk itself cost you, you need to subtract your resting burn for the same time period.
For most people, resting metabolism works out to roughly 60 to 80 calories per hour. A 5-mile walk at a moderate pace takes about 100 minutes, so you’d subtract roughly 100 to 130 resting calories from your gross total. That means a 180-pound person’s net calorie burn from walking 5 miles is closer to 350 to 380 rather than 480. This distinction matters if you’re using walking to create a calorie deficit for weight loss, because the net number reflects the true additional cost of the exercise.
How That Translates to Steps
Five miles is roughly 10,000 steps for a person of average height, based on a stride length of about 2.5 feet. But the actual count varies with your leg length. Someone who is 5’2″ takes about 2,433 steps per mile, putting their 5-mile total around 12,165 steps. Someone who is 6’0″ takes about 2,095 steps per mile, reaching 5 miles in roughly 10,475 steps. If your fitness tracker shows step counts, these conversions let you estimate distance and calorie burn without GPS.
The 10,000-step target that many trackers use as a daily goal lines up almost exactly with 5 miles for the average person. It’s a somewhat arbitrary benchmark, but it represents a meaningful chunk of physical activity, burning 350 to 600 calories depending on your size and pace, and taking 75 to 120 minutes to complete.
