Walk Your Way to Good Health! If you're inactive but healthy, start with mile-long walks at a pace of three miles per hour five times a week. Over the course of a month, gradually increase your distance to three miles at a pace of four miles per hour five times a week. If you are unable to walk that fast, walk a little farther.
I disagree with the person suggesting that an average person can go 4 mph for 24 hours straight. I think average distance for an average person walking about 3.5 mph would be about 20-25 miles in a day.Then they are going to want to eat and rest.ut you cannot run as long as you can walk. Consider a marathon. 26 miles, some people complete it in about 2 hours, others take 6 hours.But no one could keep up that high rate of running speed for 8 or 10 hours, so for both running and walking the answer would be approximately 20 miles a day.
