Otherwise, I have about the same schedule you do. I hate to lose that summer evening riding time, but I'm HUNGRY when I get home, and sometimes if I sit down to eat, I lose the Mo and have to force myself out for what turns out to be about half the ride I'd planned.
These aren't answers, but maybe they're useful suggestions:
My late meal, if it comes after about 8, has to be pretty small or it keeps me awake. I do better if I have a biggish lunch around 1:30 or 2, maybe a snack when I get home, then after the ride, a snack-sized dinner. That also seems to help me cut back on total calories a little, too, because I never get so hungry I pig out. The older you get, the more important that will be.
I'm not doing a lot of miles yet, about 100 a week, and my commute is 23 round trip. If I can do that two or three three days a week and find time for one longer ride on the weekend, I'm good for now (it will get harder in July and August, of course). But I know people who won't consider commuting part of their training, and I've never understood that. I don't have to deal with much traffic, but even if you do, you can use it for intervals and sprints.
I don't much like to ride in the very early morning, but it's not impossible this time of year. It's light enough to go at 5:30 where I live, and if I can force myself out the door, I can get in two good hours before I get to work. Fortunately, we have showers and lockers, which makes it MUCH easier.
