Hm, my best 10K is about 7:04 / mile, so that would be a 9:32. That sounds about right. I run a wide variety of paces, and tend to run a lot faster with others than by myself.
7:45 - 8:15 / mile, brisk, marginally conversational, usually in a group. I like this pace as long as I don't try to have a super-involved conversation on the uphill portions. It feels like a great workout without being unpleasantly exhausting.
8:15 - 9:30 / mile - easy / moderate run usually with others. My heart rate is a bit elevated but I'm not really breathing all that hard.
9:30 - 11:00 / mile - easy or long run by myself (often early morning or late evening or when I am otherwise not feeling 100%). My legs get tired and sore at a certain point, oddly enough sometimes my legs get more tired at a slower pace. However, I don't feel like my heart rate really gets elevated very much at all. Its still peaceful and energizing.
Interestingly enough, many elite runners run their easy runs much, much slower than their races. (race at 4:30 but train at 7:30 - 8:00 pace).
I think that the ideal training pace to racing pace ratio varies on the person. A 5k specialist should probably train fewer miles at a faster pace than a marathoner. Someone who has limited time to train should make a larger percentage of their miles high quality, than someone with a more flexible schedule.
