As an alternative, you may want to consider the Gansett Marathon, which a lot of Boston shut-outs are running. You have to have a qualifying time (I think the same as Boston) to run it, and the course, while last year in the hilly exiles of Exeter, RI, will be down along the RI shoreline. Should be a nice run. Plus, you could stay with either Redrhodie or me! Here's the info:
