How accurate is this running calorie calculator?

This calculator provides estimates based on well-established MET values for running at various speeds. Actual calorie burn can vary by 10-20% based on factors like running efficiency, terrain, weather conditions, and individual metabolism. Heart rate monitors provide more personalized estimates.

Does running burn more calories than walking?

Yes, running burns significantly more calories per minute than walking—typically about twice as much at moderate speeds. However, for the same distance covered, the total calorie difference is smaller. The main advantage of running is time efficiency for calorie burn.

Is it better to run faster or longer for burning calories?

Both approaches work. Running faster burns more calories per minute but is harder to sustain. Longer, slower runs may burn similar total calories while being more sustainable. For beginners, building duration at a comfortable pace is often more practical than pushing speed.

Why does body weight affect calories burned so much?

Running involves repeatedly lifting your body weight against gravity with each stride. A heavier body requires more muscular force and energy to propel forward. This is why calorie calculations always factor in weight—it's one of the most significant variables.

How many calories does a 5K run burn?

A 5K (3.1 miles) typically burns between 300-500 calories depending on your weight and pace. A 150-pound person running at a moderate pace burns roughly 350-400 calories. Heavier individuals or faster paces will burn more.

Should I eat before or after running?

For runs under 60 minutes, running on an empty stomach or with a light snack is fine for most people. For longer runs, eating a small meal 2-3 hours before helps maintain energy. After running, consuming protein and carbohydrates within an hour supports recovery.
