I assume the 5-8 mile runs are tempo type runs. The longish mid week run is at what pace?
I don't worry that much about pace, actually. I'd even say that for much of the year, I don't worry about pace at all. I go faster when I feel like it, slower when I feel like it. The way things work out, there will be enough days when the guys in my running group will feel like gunning it a little, that I'll wind up getting some faster miles in.
If there's an important race approaching, I'll get more structured, and have a mix of track workouts and tempo runs. (My normal running has enough hills in it that I rarely do specific hill workouts). But even then, I'll do plenty of 5-8 mile runs that are just basic runs. I'd guess anywhere from 7:45 to 9 minute miles, depending on the terrain, who I'm running with, and how I'm feeling (up to 10 minute miles on technical and/or hilly trails). My marathon race pace, for comparison, is a little under 7 minutes per mile.
The longish mid week run pace depends mostly on if I had enough sleep the night before, if there is good scenery on the running path, etc Last week it was pretty fast, just because it was cold and rainy and i wanted to get home.
