I get my M-F miles commuting, but my boys are old enough to be on there own @ home so I don't have the same problem. When they were little, though, I used to trade time with another mom so we could both work out. Also did a lot of working out in the wee hours of the morning.

There's not much traffic and with good lights on your bike, it's rather a pleasant time of day to ride. (but i'm a morning person anyway)
