Question: how many miles should i run a day to lose weight fast?
Answer: There are 3,500 calories in a pound of fat. Running one mile burns (on average) 100 calories. If you want to lose one pound of fat – then, you should run 35 miles. If you were to run 7 days a week, you would need to run 5 miles each day in order to lose one pound of fat in a week.
