Is there a reason other than time commitment you think this is not possible for most people? With 12 minute miles, it takes an hour. It takes time to build up endurance, but with pretty simple training - measuring weekly mileage and increasing that no more than 10% a week - building up to 5 miles is doable. It's challenging to and probably not advisable to do it every day due to injury risk, but I think 5 miles maybe 3-4 times a week is possible for many, barring any serious health conditions.
