There are a number of long distance commuters on this board, I am not one of them. However one thing you can do to work up to a long commute is either drive part way and then ride the rest, or drive to work, ride home in the evening and back in the next day. Either way reduces your mileage for one day and makes for a much shorter ride. Then once you are comfortable with that kind of ride you can work up to a longer ride.
