Running Calorie Calculator

Running burns approximately 80-140 calories per mile, depending on body weight and pace. A 155 lb person burns about 100 cal/mile at 6 mph. A 200 lb person burns about 130 cal/mile. Faster speeds and hills increase burn. Running consistently burns more than most other exercises per unit of time.

Yes, but less than you might think. Faster running burns more calories per minute, but since you cover more distance faster, the per-mile calorie burn changes less. Running at 8 mph burns ~30% more per mile than 5 mph. Hill running adds 50-75% more calories due to greater effort against gravity.

Running burns about 2x more calories per minute than walking at the same body weight. However, per mile, running only burns about 25-30% more than brisk walking. If you can only exercise for a set time, running wins. If you have unlimited time, the difference per mile narrows. Both are excellent for health.

Heavier people burn more calories doing the same activity because they must move more mass. Moving 220 lbs requires significantly more energy than moving 150 lbs, even at the same speed and distance. This is why calorie burn calculators always require weight as an input — it is the single biggest variable.

Slightly yes — no wind resistance, slight biomechanical differences. Setting treadmill incline to 1% compensates for the wind resistance difference. Trail running burns 10-15% more than treadmill due to uneven terrain engaging more stabilizer muscles. Treadmill calorie displays are notoriously inaccurate — use a formula-based calculator instead.
