I might be doing this race -- a nice community oriented 5 miler with a kid's fun run first. Anybody interested? You get to run across the historic North Bridge where the Minutemen kicked the Brittish butts.

Bummer! This sounds like a much more fun race than the one I signed up for with hubby. I may catch that one next year - thanks for posting it!
