A brisk walk is about 3 miles an hour, which is faster than a stroll. To get any real health benefits you need to walk over 3 mph for 20 minutes or longer in one stretch. While walking slower or in short bursts has some benefit, you need to get your heart rate up (and burn more calories) for a real cardio benefit.
In 1 hour Men age 17-25 should be able to walk about 7 miles. Men 25-35 should manage about 6.7 miles. Women in the 17-21 age range, comfortably reach 6.9 miles with Women 25-35 achieving 6.6 miles.
Over 35s Men over 35 on average walk roughly 6.5 miles in an hour. Women over 35 a little less, 6.3 miles.
Over 60s Men over 60, on average walk 6.2 miles in an hour while Women over 60 walk 6.1 miles.
Safety It goes without saying, consult your doctor before starting any exercise program especially as you get older, if you have health concerns or have not had a recent check up.
