How to Use These Calorie Charts
These reference tables provide standard baseline estimates based on sports science research. While very helpful for trip planning, your actual calorie burn will also depend on four practical factors:
Your Body Weight
Heavier hikers burn more total calories because moving a larger body weight against gravity takes more physical work on every step.
Trail Surface & Footing
Walking on loose gravel, mud, sand, or snow burns 20% to 50% more calories than walking on a firm dirt trail or road.
Climbing & Downhill Braking
Climbing lifts your body weight against gravity, while steep downhills force your thigh muscles to brake each step, burning extra calories.
Pack-to-Body Weight
Carrying 30 lbs feels much heavier to a 120 lb hiker (25% of body weight) than to a 220 lb hiker (14% of body weight).
