Question: how many calories will you burn if you walk 5 miles?
Answer: Most rough estimates revolve around 100 calories burned per mile for a 180-pound person. And 10,000 steps is roughly 5 miles. So assuming you weigh 180 pounds then yes, by simple mathematics, 100 calories x 5 miles equals 500 calories. Over the course of a week that becomes 3,500 calories.
