Calories Burned. A half mile is a relatively short distance to run, so you shouldn't expect a big calorie burn. According to the website Cool Running, a 200-pound person will burn 79 calories running half a mile. A 175-pound person will use less energy, burning just 69 calories per half mile.
Like it or not, running makes for a really great cardio workout: Maintain a six-mile per hour pace, and you'll burn upwards of 557* calories in one hour! And even if running that fast for that long** seems like a bit of a stretch, you can still burn an impressive 398 calories per hour by jogging.
