I almost did it again today.
There was a problem. 3 miles in, I got a call from a coworker asking: "So.... when are you coming in?" I was kind of hoping he was joking, because he's a practical joker that way.
Did make for a pretty good tempo run on the way back, tho. It's pretty difficult terrain- relatively hilly (for Michigan) with snow and ice to make things interesting. Rocks, roots, and other random bits make for a treacherous path even on good days.
Still, I maintained a 8:30 pace or so for the three miles back, dropping about 2 minutes/mile from the way out. Sadly, though, I was an hour late on the first day of the sale. On the plus side, there were still four or five employees there, and one was kind enough to stay over an extra hour covering for me.
I just don't know if I'll make my 47-50 mile goal this week, though. Oh well, we'll see. :)
