If I lived closer, I would TOTALLY run with you! That's about my pace right now, too, and I keep getting the (albeit gentle) cold shoulder at a lot of my area running groups.
Without much luck, I have been scouring craigslist and the meetup sites - there are some folks out there, but I haven't yet managed to find any really long term running buddies.
Hang in there, stay open to groups that might be single-oriented but still welcoming to someone off-the-market. You could become an advice guru to the others while you run!
Good luck, and keep us posted on any races you'll be doing out of MI - It'd be great to meet up with you and run a race sometime...with someone our own pace!
Take care,
Jennifer
