Rucking Calorie Calculator
Estimate calories burned rucking — carrying a weighted pack while walking. Enter your body weight, pack weight, pace, and distance or duration to get total calories burned, calorie rate per hour and per mile, and how rucking compares to regular walking and running at the same pace.

Choose a unit system and use a quick preset or enter your own values. Pack weight significantly increases calorie burn — the heavier the ruck, the more energy required at the same pace.
How calories are estimated
This calculator uses a MET (Metabolic Equivalent of Task) approach. Base walking MET is adjusted upward based on pack weight relative to body weight — heavier pack = higher MET. Calories = MET × body weight (kg) × hours. Female adjustment: −8% average.
Rucking vs running
A 180 lb person rucking with a 30 lb pack at 20 min/mile burns roughly the same calories per mile as running at 10 min/mile — with much lower joint impact. This is why rucking is used by military units and increasingly popular for fat loss with lower injury risk.
Frequently asked questions
How many calories does rucking burn per hour?
It depends on body weight, pack weight, and pace. A 180 lb person rucking with a 30 lb pack at a 20 min/mile pace burns approximately 400–500 calories per hour. Heavier pack or faster pace increases the rate significantly. As a rough rule, rucking burns 2–3× more calories than walking at the same pace.
How much does pack weight affect calorie burn?
Significantly. Each additional 10% of body weight in your pack adds roughly 8–12% to calorie burn above baseline walking. A 30 lb pack on a 180 lb person (17% of body weight) increases burn by approximately 15–20% compared to walking with no load.
What is a good rucking pace?
Military standard is 15 min/mile (4 mph) with a 35–45 lb pack. Beginners typically start at 20 min/mile (3 mph) with 15–20 lb. GORUCK events often target 15–18 min/mile with 20–30% body weight. The key is maintaining a pace where you can still hold a conversation.
Is rucking good for weight loss?
Yes — rucking combines high calorie burn with low joint impact compared to running. The added pack weight elevates heart rate and calorie expenditure significantly above walking without the repetitive impact stress of running. Regular 3–5× weekly sessions create a substantial weekly calorie deficit.
How does rucking compare to running for calories?
Rucking with a heavy pack at a slow pace burns a similar number of calories per mile to running at a moderate pace. A 180 lb person burns roughly 120 calories per mile running vs 100–130 calories per mile rucking with a 30 lb pack — while experiencing much lower impact on joints.
