Fortunately, my commute to school and work was planned out when I moved to my condo. I have a 6 mile round trip (between all 3) daily. So I can still accommodate my pleasure/training rides without worrying about going deep into mileage debt (how I define it. Probably not the right terminology) by just pedaling to work and the university.
Mind you, I'm still intentionally adding anywhere from 20-50 miles in the mornings that could be considered my "commuting" mileage, I suppose.
