Walking 10 miles burns roughly 700 to 1,400 calories for most people, with your body weight and walking speed being the two biggest factors. A 160-pound person walking at a typical pace will burn about 850 calories over that distance, while a 200-pound person covers the same ground for about 1,063 calories.
Calories Burned by Weight and Pace
Your body weight has the single largest effect on how many calories you burn walking any distance. Heavier bodies require more energy to move, so a 220-pound person burns nearly twice as many calories as a 120-pound person covering the same 10 miles. Speed matters too, but less than most people expect.
At a typical walking pace (2.5 to 3.5 mph):
- 120 lbs: 638 calories
- 140 lbs: 744 calories
- 160 lbs: 850 calories
- 180 lbs: 957 calories
- 200 lbs: 1,063 calories
- 220 lbs: 1,170 calories
At a brisk to vigorous pace (4.5 mph):
- 120 lbs: 764 calories
- 140 lbs: 891 calories
- 160 lbs: 1,018 calories
- 180 lbs: 1,145 calories
- 200 lbs: 1,273 calories
- 220 lbs: 1,400 calories
At a very fast walking pace (5.0 mph), the numbers climb further. A 180-pound person burns about 1,309 calories, and a 200-pound person hits 1,455. That said, 5.0 mph is essentially race-walking, and most people would naturally break into a jog at that speed.
Why Speed Changes the Burn
The energy cost of walking isn’t just about distance. Exercise scientists measure intensity using metabolic equivalents, or METs, which compare an activity’s energy demand to sitting still. Walking at 2.5 mph registers about 3.0 METs. Push that to 3.5 mph (a brisk pace) and it jumps to 4.8 METs. At 4.0 mph, you’re at 5.5 METs, nearly double the intensity of a casual stroll.
This explains why a brisk 10-mile walk burns 15 to 20 percent more calories than the same distance at a relaxed pace. You’re covering the same ground, but your muscles are working harder with each stride, your heart rate is higher, and your body pulls more fuel to keep up.
How Long 10 Miles Actually Takes
Ten miles is a serious walk. At a brisk pace of 3 mph, expect it to take about 3 hours and 20 minutes. Slow that down to a comfortable 2.5 mph and you’re looking at 4 hours. At 4.0 mph, which most people would consider fast, you’d finish in about 2.5 hours. For context, the average person rarely walks more than 3 to 4 miles in a normal day, so 10 miles represents a significant time commitment no matter your speed.
Carrying Weight Increases the Burn
If you walk with a loaded backpack (sometimes called rucking), the calorie cost rises substantially. As a general rule, rucking burns two to three times more calories than unweighted walking, depending on how much you carry, how fast you move, and the terrain. A 180-pound person carrying a 30- to 40-pound pack on flat ground can roughly double their energy expenditure compared to walking empty-handed at the same speed.
Hills have a similar multiplying effect. Walking uphill forces your muscles to work against gravity, which increases intensity in the same way added weight does. A hilly 10-mile route can push your calorie burn well above what the flat-ground numbers suggest.
Walking vs. Running the Same Distance
Running 10 miles burns roughly double the calories of walking the same distance. This surprises people who’ve heard that “a mile is a mile” regardless of speed. While it’s true that walking and running both move your body the same distance, running involves a brief airborne phase in each stride where your muscles absorb and generate much more force on landing. That mechanical difference costs extra energy per mile.
The trade-off is that walking 10 miles is accessible to far more people than running it. The injury risk is dramatically lower, the recovery is easier, and you can do it more frequently without breaking down. For calorie burning through distance, walking is the slower but more sustainable option.
The Afterburn Effect Is Minimal
You may have heard that exercise keeps burning calories after you stop. This post-exercise oxygen consumption is real, but it’s driven primarily by exercise intensity, not duration. High-intensity activities like sprinting or heavy resistance training produce a measurable afterburn. Steady-state walking, even for 10 miles, produces a much smaller effect. The calories listed above are essentially what you get. Don’t count on a significant bonus burn after you stop walking.
What This Means for Weight Loss
The old rule of thumb is that 3,500 calories equals about one pound of body fat. By that math, a 180-pound person walking 10 miles (burning roughly 957 calories) would need to do it about 3.5 times to lose a pound. In practice, the relationship is messier than that. When you lose weight, you lose a mix of fat, lean tissue, and water. Your body also adapts over time, becoming more efficient and burning slightly fewer calories for the same activity.
A more realistic expectation, per Mayo Clinic guidance, is that cutting or burning 500 calories per day leads to roughly half a pound to one pound of weight loss per week. A 10-mile walk gets most people close to or past that 500-calorie threshold in a single session, making it a powerful tool if you can fit it into your schedule regularly. Even splitting it into two 5-mile walks produces the same total burn.
The practical challenge is time. A 10-mile walk takes 3 or more hours, which makes it hard to do daily. For many people, shorter walks of 3 to 5 miles at a brisk pace, done consistently, end up producing better long-term results simply because they’re easier to maintain week after week.
