Lots of good advice here. Personally, I get most of my miles during the week before work. I only live 4 miles from the office but most mornings I'll either meet my buddy for a 20 mile tempo ride or I'll do a solo TT on the long way into work. Saturdays I'll race or go on the local hammerfest group ride. Sundays I'm either off the bike or going on a mellow ride with the kids. (I have 4-year old twins. My son is off training wheels and loves to ride alongside. My daughter is still on training wheels and prefers the trailer bike.)
Get the family involved, if possible. Make it fun. It's really the best Dad Time with your kids. And stop feeling guilty about taking good care of yourself. You're going to be a Dad for a long time and you need to be happy and healthy for yourself, your wife, and your kids!
Here's me and the Wonder Twins from July 4:
