This is very difficult to do considering that:

How many miles should i run to lose 20 pounds. Running one mile burns (on average) 100 calories. If you weigh 160 pounds, you would have to walk 40 minutes per day at a pace of 10 miles per. 3,500 calories per pound x 20 pounds = 70,000 total calories.

A man of 6 feet tall who weighs 200 pounds will have to walk about 725 miles. Running 1 mile burns about 100 calories (round number). If you were to run 7 days a week, you would need to run 5 miles.

But if you have to walk (or run) 35 miles to lose one pound, you have to walk (or run) 700 miles to lose 20 pounds. This is basically a math question. 20 pounds equals 70,000 calories (20 miles x 3,500 calories/pound).

This will take him about. That translates to a race time improvement of 0.64 percent per pound lost—or, for these runners (who were running at about 6:00/mile), 2.4 seconds per mile per pound. 70,000 calories / 14 days = 5,000 calories per day.

If you run 3 miles in 30 minutes, that is roughly 300 calories that you burned. It will take you 175 hours to walk at approximately 4 miles per hour. The amount of calories you burn each week will depend on your.

If you want to lose 20 pounds by walking alone, you need to burn at least 250 calories per day. But if you have to walk or run 35 miles to lose one pound you have to walk or run 700 miles to lose 20 pounds. Therefore, approximately 9.7 calories are burned by a person weighing 180 pounds in one minute and 7.6 calories by someone weighing 140 pounds.
