Walking 10 miles burns roughly 700 to 1,200 calories for most people, with your body weight being the single biggest factor in where you fall on that range. A 180-pound person burns about 96 to 102 calories per mile on flat ground, putting a 10-mile total around 960 to 1,020 calories. Lighter individuals burn less, heavier individuals burn more, and pace and terrain shift the numbers further.
Calories Burned by Body Weight
Your body has to move its own mass with every step, so heavier people burn more energy covering the same distance. The relationship is essentially linear: a person who weighs twice as much burns close to twice the calories over the same route.
A useful formula relies on MET values (a standard measure of exercise intensity) published in the Compendium of Physical Activities. For a moderate walking pace of about 3 to 3.4 mph, the MET value is 3.8. You can estimate calories per minute with this: MET × body weight in kg × 3.5 ÷ 200. Multiply that by the total minutes walked and you get your gross calorie burn, including what your body would have burned at rest anyway.
Here’s what 10 miles at a moderate pace looks like for different weights:
- 130 lbs (59 kg): approximately 650 to 750 calories
- 155 lbs (70 kg): approximately 780 to 880 calories
- 180 lbs (82 kg): approximately 960 to 1,020 calories
- 205 lbs (93 kg): approximately 1,050 to 1,150 calories
These are gross numbers. Your body would have burned some calories simply sitting still during the same time period. The “net” burn, meaning the extra calories from walking itself, is roughly 15 to 20% lower. If you’re tracking calories for weight loss, the net number is the more honest figure.
How Walking Speed Changes the Burn
Pace matters more than most people expect. The Compendium of Physical Activities assigns progressively higher MET values as speed increases:
- 2.5 mph (easy stroll): MET 3.0
- 3.0 to 3.4 mph (moderate): MET 3.8
- 3.5 to 3.9 mph (brisk): MET 4.8
- 4.0 to 4.4 mph (very brisk): MET 5.5
That’s a big jump. A 155-pound person walking 10 miles at an easy 2.5 mph pace burns around 620 calories gross, while the same person pushing a very brisk 4.0 mph pace burns closer to 1,140 calories. The difference is almost double, even though the distance is identical. At higher speeds, your muscles work harder to maintain a gait that your body isn’t naturally optimized for. Interestingly, once walking speed exceeds about 5 mph, walking actually becomes less efficient than running because the coordination required to walk that fast demands more muscle activation without the elastic energy return your tendons provide during a running stride.
How Long 10 Miles Takes
Ten miles is a significant walk. At a brisk pace of 3 mph, expect it to take roughly 3.5 hours. At 4 mph, you’re looking at 2.5 hours. A leisurely 2.5 mph pace stretches the outing to 4 hours.
Most people don’t walk 10 miles in a single session regularly, so if you’re building up to it, your actual pace will likely slow in the later miles. That doesn’t reduce your total calorie burn much, since distance is the primary driver, but it does mean the walk takes longer than a simple calculation might suggest.
Hills and Terrain Add Up Fast
Walking uphill dramatically increases calorie expenditure. For every 1% increase in grade, a 150-pound person burns about 10 additional calories per mile, roughly a 12% increase. Over 10 miles, even gentle rolling hills can add 100 to 300 calories to your total compared to the same distance on flat ground.
Terrain type also plays a role. Walking on sand, gravel, or uneven trails forces your stabilizing muscles to work harder and reduces the efficiency of each stride. Military researchers developed a well-known predictive equation (the Pandolf equation) that accounts for body weight, walking speed, terrain type, slope, and any load you’re carrying. The terrain factor alone can increase energy cost by 50% or more when you move from a paved road to soft sand. If you’re hiking a trail with a loaded daypack, your 10-mile burn could easily exceed 1,500 calories.
Body Composition Plays a Quieter Role
Two people who weigh the same but carry different ratios of muscle to fat won’t burn identical calories. Muscle tissue contributes about 20% to total daily energy expenditure, while fat tissue contributes only about 5% (in someone with roughly 20% body fat). Muscle burns an estimated 10 to 15 calories per kilogram per day at rest, and that metabolic premium carries over into exercise. A more muscular person at 180 pounds will burn somewhat more than a less muscular person at the same weight, though the difference over a single walk is modest, likely in the range of 5 to 10%.
The bigger impact of body composition is long-term. Building and maintaining muscle raises your baseline calorie burn throughout the day, so the same 10-mile walk represents a slightly smaller fraction of a more muscular person’s total daily expenditure.
Walking vs. Running the Same Distance
A common question is whether walking 10 miles burns the same calories as running 10 miles. It doesn’t. Running involves much greater vertical oscillation of your center of mass, meaning your body moves up and down more with each stride. That extra vertical work is the main reason running consumes more energy per mile than walking. Running also produces a larger “afterburn” effect, where your body continues using extra energy after the activity ends.
For a 155-pound person, running 10 miles burns roughly 1,100 to 1,300 calories, compared to 780 to 1,000 for walking the same distance. The gap narrows somewhat at very brisk walking speeds, but running remains more energy-costly at every comparable distance.
That said, walking 10 miles is far easier on your joints and sustainable for a much wider range of fitness levels. If the goal is calorie burn and you have the time, walking the full distance still produces a substantial deficit.
A Quick Way to Estimate Your Burn
If you want a fast, reasonably accurate number without plugging into a calculator, use this shortcut: multiply your body weight in pounds by 0.53 for a moderate pace (about 3 mph) or by 0.67 for a brisk pace (about 3.5 to 4 mph). That gives you an approximate calorie burn per mile. Multiply by 10 for the full distance.
For example, a 170-pound person at a brisk pace: 170 × 0.67 = about 114 calories per mile, or roughly 1,140 calories for the full 10 miles. Add 10 to 12% per percentage point of incline if you’re walking hills, and subtract about 15 to 20% if you want the net burn (calories above what you’d burn sitting still).
