Question: how many calories are burned in a 20 minute mile?
Answer: A very rough rule of thumb is that, if you have an average healthy body weight, you'll burn roughly 100 calories for every mile you cover. So, if you cover 1 1/2 miles in 20 minutes, you'll burn about 150 calories. If you're a faster runner and cover 3 miles, you'll burn roughly 300 calories in the same amount of time.
