How Hiking Calorie Burn Works
Hiking calorie burn is the total energy expenditure during a hike, determined by body weight, pack weight, distance, elevation gain, terrain difficulty, and hiking speed. According to the American Council on Exercise (ACE), hiking burns between 430 and 550 calories per hour for a 155-pound person on moderate terrain, making it one of the most effective outdoor exercises for calorie expenditure. The Compendium of Physical Activities, maintained by Arizona State University and widely used in exercise science, assigns hiking a MET (Metabolic Equivalent of Task) value of 5.3 to 7.8 depending on terrain and grade, compared to 3.5-4.0 METs for flat-ground walking.
What makes hiking uniquely calorie-intensive is the combination of elevation change, uneven footing, and load bearing. Research published in the Journal of Applied Physiology found that uphill walking at a 10% grade increases metabolic cost by approximately 50% compared to level walking at the same speed. Use this calculator alongside our daily calorie calculator and TDEE calculator to integrate hiking into your overall energy balance.
The Hiking Calorie Formula
This calculator uses a modified Pandolf equation, originally developed by the U.S. Army Research Institute for predicting energy expenditure during load carriage over varied terrain. The simplified version is:
Calories = MET x Body Weight (kg) x Duration (hours)
- MET — Metabolic Equivalent of Task, adjusted for terrain type (trail = 5.3, rough = 6.5, off-trail = 7.5) plus elevation and pack weight modifiers
- Body Weight (kg) — total weight including body weight and pack weight, converted from lbs using x 0.4536
- Duration (hours) — estimated from distance and hiking speed, which varies by terrain and elevation
Worked example: A 170-lb person with a 15-lb pack hiking 5 miles on a maintained trail with 1,500 feet of elevation gain. Total weight = 185 lbs = 83.9 kg. Base MET = 5.3 + elevation modifier (1,500/5/500 x 0.5 = 0.3) + pack modifier (15/20 x 0.5 = 0.375) = 5.975. Speed = 2.5 mph adjusted for elevation = 2.0 mph. Duration = 2.5 hours. Calories = 5.975 x 83.9 x 2.5 = 1,253 kcal.
Key Terms You Should Know
- MET (Metabolic Equivalent) — a measure of exercise intensity. 1 MET equals the energy expenditure at rest (~1 kcal/kg/hour). Hiking ranges from 5.3 to 7.8 METs depending on conditions.
- Elevation Gain — the total vertical ascent during a hike, measured in feet or meters. Does not include descent. A 1,000-foot gain per mile is considered very steep.
- Naismith's Rule — a hiking time estimation that allows 1 hour for every 3 miles of horizontal distance plus 1 hour for every 2,000 feet of ascent.
- Base Weight — your body weight without a pack. Used as the starting point for calorie calculations.
- Total Skin-Out Weight — body weight plus everything you carry, including clothing, pack, water, and gear.
Hiking vs. Other Activities: Calorie Comparison
The table below compares hourly calorie burn for a 170-pound person across common outdoor activities, based on data from the Compendium of Physical Activities.
| Activity | MET Value | Calories/Hour (170 lbs) | Equivalent Walk Distance |
|---|---|---|---|
| Walking (flat, 3.5 mph) | 3.5 | 270 | 3.5 miles |
| Hiking (trail, moderate) | 5.3 | 409 | 2.5 miles |
| Hiking (steep, heavy pack) | 7.8 | 602 | 1.5 miles |
| Running (6 mph) | 9.8 | 756 | 6 miles |
| Cycling (12-14 mph) | 8.0 | 617 | 13 miles |
| Swimming (moderate) | 7.0 | 540 | N/A |
Practical Hiking Calorie Examples
Example 1 — Day hike: A 150-lb woman carries a 10-lb daypack on a 7-mile maintained trail with 2,000 feet of elevation gain. Total weight = 72.6 kg. Adjusted MET = 6.2. Estimated speed = 2.0 mph. Duration = 3.5 hours. Calories burned = 6.2 x 72.6 x 3.5 = 1,575 kcal. That equals about 5 standard meals worth of energy. Check your macro needs to plan post-hike nutrition.
Example 2 — Backpacking trip: A 200-lb man carries a 35-lb overnight pack on a rough 12-mile trail with 3,500 feet of elevation gain. Total weight = 106.6 kg. Adjusted MET = 8.0. Speed = 1.5 mph. Duration = 8 hours. Calories burned = 8.0 x 106.6 x 8.0 = 6,822 kcal. Multi-day backpackers typically need 3,500-5,000 calories per day to maintain energy balance.
Example 3 — Flat nature walk: A 130-lb person walks 3 miles on a flat, paved trail with no elevation gain and no pack. Weight = 59.0 kg. MET = 4.0. Speed = 3.0 mph. Duration = 1 hour. Calories = 4.0 x 59.0 x 1.0 = 236 kcal. Compare this with the steep hike example to see how dramatically elevation and pack weight affect calorie burn.
Tips to Maximize Hiking Calorie Burn
- Choose routes with elevation gain: Uphill sections burn 50-100% more calories per mile than flat terrain. Even moderate inclines of 5-10% significantly increase energy expenditure.
- Add a weighted pack progressively: Start with a light pack and gradually increase weight. A 20-lb pack increases calorie burn by 10-15% without dramatically slowing your pace.
- Use trekking poles on steep terrain: Poles engage upper-body muscles, increasing total calorie burn by an estimated 15-20% according to research in the Journal of Sports Sciences.
- Vary your terrain: Off-trail or rocky terrain forces more stabilization work, engaging core and ankle muscles that are underused on smooth paths. Use our body fat calculator to track fitness progress over time.
- Hike longer, not necessarily faster: Duration is the biggest driver of total calorie burn. A 4-hour moderate hike burns more total calories than a 1-hour intense hill climb.
- Stay hydrated and fueled: Dehydration reduces hiking efficiency by up to 25%. Drink 0.5-1 liter of water per hour and eat 200-300 calories every 2 hours on long hikes.
Frequently Asked Questions
How many calories does a 5-mile hike burn?
A 5-mile hike typically burns between 500 and 1,200 calories depending on body weight, pack weight, elevation gain, and terrain. For a 170-pound person on a moderate trail with 1,000 feet of elevation gain and a 15-pound daypack, expect approximately 700-800 calories burned over 2-2.5 hours. On flat terrain with no pack, the same hike burns closer to 500 calories. On steep, rocky terrain with a heavy pack, calorie burn can exceed 1,000 calories. The biggest variable is elevation gain, which can double energy expenditure per mile.
Does carrying a backpack burn more calories while hiking?
Yes, carrying a backpack significantly increases calorie burn during hiking. Research from the U.S. Army Research Institute shows that every pound of pack weight adds approximately 0.5-1.0% to total energy expenditure. A 20-pound daypack increases calorie burn by roughly 10-15% compared to hiking unloaded. A 40-pound overnight pack can increase burn by 20-30%. The additional weight forces your muscles to work harder with every step, particularly your legs, core, and back. For weight loss goals, pack weight is an effective way to increase exercise intensity without changing your route.
How does elevation gain affect hiking calorie burn?
Elevation gain is the single biggest factor in hiking calorie expenditure after body weight. According to research published in the Journal of Applied Physiology, walking uphill at a 10% grade increases metabolic cost by approximately 50% compared to level walking at the same speed. For every 500 feet of elevation gain per mile, expect roughly a 50% increase in calories burned per mile. A hike with 3,000 feet of gain over 6 miles burns nearly twice the calories of the same distance on flat ground. Use our running calorie calculator to compare with uphill running expenditure.
Is hiking better exercise than walking for weight loss?
Hiking generally burns 30-60% more calories per hour than flat-ground walking due to uneven terrain, elevation changes, and load bearing. The Compendium of Physical Activities assigns trail hiking a MET of 5.3-7.8 versus 3.5-4.0 for brisk walking. Beyond calorie burn, hiking engages more stabilizing muscles in the ankles, knees, hips, and core, providing superior strength and balance training. Hiking also tends to be more sustainable as exercise because the scenery and exploration aspect increases motivation and duration compared to repetitive treadmill walking.
How should I fuel during a long hike?
For hikes lasting over 2 hours, the American College of Sports Medicine recommends consuming 30-60 grams of carbohydrates per hour (120-240 calories) to maintain energy levels. Good trail snacks include trail mix, energy bars, dried fruit, and nut butter sandwiches. Drink 0.5-1 liter of water per hour, more in hot conditions or at altitude. For all-day hikes burning 3,000+ calories, plan a substantial meal at the midpoint. Post-hike, consume a meal with both protein and carbohydrates within 2 hours to support muscle recovery.
