I have a similar dilemma. Even tho daddy is in the house I pretty much function as a single parent. Could you take your bike to work and do your rides after work, without going home first? I understand the difficulty and guilt in leaving after the "mommy's home celebration"! I know I'm a lot more able to concentrate on being with my son if I've taken care of myself first, and taking care of myself means getting a ride in !

I'm in Texas, so I know about the late day heat, but this strategy might work for a few more weeks, anyway .
