Running Calorie Calculator

Calculate calories burned running based on your weight, distance, and pace.

Quick Answer

A 155 lb person running 3 miles at a 10:00 min/mile pace burns approximately 330 calories in 30 minutes. That is about 110 calories per mile.

About This Tool

The Running Calorie Calculator estimates calories burned during a run based on your body weight, distance, and pace. It uses MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities to provide accurate estimates for different running speeds.

Running is one of the most efficient exercises for burning calories. It engages large muscle groups across your entire body and maintains an elevated heart rate throughout. Compared to walking the same distance, running burns roughly 30-40% more calories due to the greater mechanical work required to propel your body through the air between strides.

Frequently Asked Questions

How many calories does running burn?
Running burns roughly 80-140 calories per mile depending on your weight and pace. A 155 lb person running at 6 mph burns about 100 calories per mile. Heavier runners burn more calories per mile because they are moving more mass. Faster paces burn more calories per minute but roughly the same per mile -- the key variable is total distance covered.
Does running faster burn more calories?
Running faster burns more calories per minute due to a higher MET value (metabolic equivalent). However, calories per mile are surprisingly similar across paces. A 155 lb person burns about 95-110 calories per mile regardless of speed. The advantage of faster running is time efficiency -- you burn the same calories in less time. For total calorie burn, distance matters more than speed.
Is running or walking better for calorie burn?
Running burns about 30-40% more calories per mile than walking due to the higher MET value and greater mechanical effort. A 155 lb person burns about 100 cal/mile running vs 70 cal/mile walking. However, walking is lower impact, more sustainable for beginners, and easier on joints. For weight loss, consistency matters more than intensity -- choose what you will do regularly.
How accurate are calorie burn estimates?
MET-based estimates have a margin of error of 15-20% for most people. Individual variation depends on fitness level, running efficiency, terrain, temperature, wind, and body composition. Trained runners are more efficient (burn fewer calories at the same pace). Heart rate monitors and GPS watches provide more personalized estimates by accounting for individual effort level.
How many miles should I run per week?
For general health, 15-20 miles per week (or 150 minutes of moderate running) is recommended. For weight loss, 20-30 miles per week with a caloric deficit is effective. Competitive runners may run 30-70+ miles weekly. The 10% rule suggests increasing weekly mileage by no more than 10% to avoid injury. Rest days are essential for recovery and injury prevention.
