Manchester 1/2 Marathon This Weekend

I guess you could file this under "what was I thinking...". I was hoping to run a fast half this fall but I may end up running half fast instead (sorry, I couldn't resist). Although the 1/2 marathon is my FAVORITE distance by far (pun intended), rumor has it the Manchester Half has a few hills and is considered 'challenging'.
I'm heading up to Manchester on Saturday for packet pickup and plan to drive most of the course afterwards. I don't like surprises. Hills are ok, STEEP hills suck (up or down).

Should be somewhat interesting to run considering the full marathon and the half both start at the same time AND run nearly the entire 13.1 miles together (the full takes a right at the finish on Elm St and the half takes a left).

Looks like great weather though: sunny but cold (temps may be in the 20's at the start, yikes).
