Calories burned hiking: How many calories do you burn on a hike?
Hiking is one of the most effective and enjoyable ways to increase daily energy expenditure, improve cardiovascular health, and support sustainable fat loss. Whether you are walking a gentle forest trail or climbing a steep mountain path with a backpack, hiking can significantly increase the number of calories burned compared to regular walking on flat ground.
But how many calories do you burn on a hike? The answer depends on several variables, including body weight, hiking speed, terrain grade, pack weight, altitude, and total duration. In this guide, we will break down the science behind calories burned hiking, provide formulas and tables, and explain how to estimate your personal energy expenditure accurately.
What determines calories burned hiking?
Calories burned during hiking are influenced by both internal and external factors. Understanding these variables allows you to estimate energy expenditure more precisely.
1. Body weight
The heavier you are, the more energy your body needs to move. Energy cost increases proportionally with body mass. For example, a 90 kg person burns significantly more calories hiking than a 60 kg person at the same pace and terrain.
2. Hiking speed
Walking at 2 mph on flat terrain requires far less energy than hiking at 4 mph uphill. Faster movement increases heart rate, oxygen consumption, and metabolic demand.
3. Terrain and incline
Elevation gain dramatically increases calorie burn. Uphill hiking activates glutes, hamstrings, and calves more intensely, increasing total energy expenditure. Rocky or uneven trails also demand greater stabilization effort.
4. Backpack weight
Carrying a loaded backpack increases the metabolic cost of hiking. Even an additional 5 to 10 kg can meaningfully increase calories burned per hour.
5. Duration
Total calories burned equals calories per minute multiplied by total time. Longer hikes naturally increase total energy expenditure.
The science behind calories burned hiking
Energy expenditure during physical activity is commonly estimated using MET values. MET stands for Metabolic Equivalent of Task. One MET represents energy expenditure at rest.
The formula used to estimate calories burned is:
Calories burned per minute = (MET × body weight in kg × 3.5) ÷ 200
Total calories burned:
Total calories = calories per minute × total minutes
Typical MET values for hiking:
- Hiking on flat terrain - 5 to 6 METs
- Moderate uphill hiking - 6 to 7 METs
- Steep uphill or backpacking - 7 to 9 METs
Calories burned hiking table by body weight
The table below shows approximate calories burned per hour hiking at moderate intensity on mixed terrain at about 6 METs.
| Body Weight | Calories Burned Per Hour |
|---|---|
| 60 kg | 378 kcal |
| 70 kg | 441 kcal |
| 80 kg | 504 kcal |
| 90 kg | 567 kcal |
| 100 kg | 630 kcal |
These numbers increase substantially with steeper terrain or additional backpack weight.
Flat trail vs uphill hiking
Let us compare two practical examples for a 75 kg individual hiking for 2 hours:
- Flat terrain at 5 METs: approximately 787 kcal total
- Steep uphill at 8 METs: approximately 1260 kcal total
The incline nearly doubles energy expenditure. This explains why mountain hiking is often considered both strength training and cardiovascular exercise combined.
Backpacking and load carriage impact
Carrying a backpack increases caloric expenditure due to additional mechanical work and postural stabilization. Research shows that adding 10 to 20 percent of body weight can increase calorie burn by 10 to 25 percent, depending on terrain.
For example, a 80 kg hiker carrying a 12 kg backpack on moderate terrain may burn 600 to 700 kcal per hour instead of 500 kcal.
Calories burned hiking vs walking
Many people ask how hiking compares to walking on a treadmill or pavement.
| Activity | Average MET | Calories per Hour at 75 kg |
|---|---|---|
| Walking 3 mph flat | 3.5 | 276 kcal |
| Hiking moderate trail | 6 | 472 kcal |
| Steep uphill hiking | 8 | 630 kcal |
Hiking typically burns 50 to 100 percent more calories than casual walking due to elevation change and uneven terrain.
How to calculate your personal calorie burn
To estimate your own calories burned hiking:
- Determine your body weight in kilograms.
- Estimate hike intensity using MET values.
- Multiply MET × weight × 3.5 ÷ 200.
- Multiply the result by total minutes hiked.
If you prefer a faster method, you can use a structured tool like this interactive hiking energy expenditure estimator to input your weight, pace, and duration for a more personalized result.
Does hiking help with weight loss?
Yes, hiking supports weight loss when combined with a calorie deficit. Fat loss occurs when total daily energy expenditure exceeds calorie intake. Hiking increases your Total Daily Energy Expenditure by adding non sedentary activity and aerobic workload.
For example:
If your maintenance calories are 2500 kcal per day and you burn an additional 600 kcal hiking, your effective energy balance shifts significantly. Over time, consistent hiking can contribute to meaningful fat loss.
Additional benefits beyond calorie burn
While calories burned hiking are important for weight management, hiking also provides:
- Improved cardiovascular endurance
- Lower resting heart rate
- Stronger lower body muscles
- Improved insulin sensitivity
- Reduced stress levels
Outdoor hiking also provides mental health benefits due to nature exposure and reduced screen time.
How altitude affects calorie burn
At higher elevations, oxygen availability decreases. Your body compensates by increasing breathing rate and heart rate, which can slightly increase calorie expenditure. However, reduced pace due to fatigue may offset some of this increase.
Overall, moderate altitude may increase metabolic demand by 5 to 10 percent compared to sea level hiking.
Practical recommendations for maximizing calorie burn
Increase elevation gain
Select trails with steady incline rather than flat loops.
Use interval hiking
Alternate faster uphill sections with moderate recovery walking.
Add safe backpack load
Progressively increase pack weight to safely increase metabolic demand.
Extend duration
Longer hikes increase total calories burned without necessarily increasing intensity.
Track performance
Use a smartwatch or heart rate monitor to better estimate energy expenditure.
Common questions about calories burned hiking
Is hiking considered cardio?
Yes. Hiking elevates heart rate into aerobic zones, especially on incline terrain.
Is hiking good for belly fat?
Spot reduction is not possible, but hiking contributes to overall fat loss when part of a calorie deficit.
How many calories does a 5 mile hike burn?
This depends on pace and elevation. A 75 kg person may burn 400 to 700 kcal depending on terrain difficulty.
Key takeaways
Calories burned hiking depend on body weight, terrain, incline, backpack weight, and total duration. Steeper and longer hikes dramatically increase total energy expenditure. Using the MET formula or a reliable estimation tool allows you to plan hikes strategically for weight loss or endurance goals.
Hiking remains one of the most sustainable forms of exercise because it combines calorie burn, strength engagement, and mental restoration in one activity.
