>Gears and Wears>Pace bracelet
I find myself running by perceived effort. Typically, the pace takes care of itself. Just my $0.02. Good luck this weekend!
I just thought it was a neat (free) tool that some people may find helpful.

I think pace bracelets help the most by keeping people from going out too fast in a marathon.
