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.
Men age 17-25 should complete 5 miles in a 83 minute period and Men 25-35 should complete 5 miles in 87 minutes. Women in the 17-21 age range, should complete 5 miles in 85 minutes with Women 25-35 achieving 88 minutes.
Over 35s Men over 35 should complete 5 miles in a 90 minute period and Women over 35 should complete 5 miles in 92 minutes.
Over 60s Men over 60, should complete 5 miles in 93 minutes with Women over 60 managing it in 95.
Safety It goes without saying, consult your doctor before starting miles, especially as you get older, if you have health concerns or have not had a recent check up.
1 mile should take about 17 minutes on average.
