The OP did not describe the topography of his commute. A 22 mile flat commute is going to be much more manageable than a 22 mile hilly commute. Over time, speed will increase to the point that the commute will not be taking two hours to complete...

I have a 18 mile each way hilly commute and I can get to work in right around an hour and back home in about an hour and ten minutes. It took a couple of years of dedicated commuting to work up to those times. I started by riding a couple days/week and kept working up to riding every day.
