also, watertown is nice that its on the charles, thus lots of good running. newton is nice that you get access to the marathon course, also more good running. assuming you care about that and all, as this is LRC.
I agree about on-street parking situations in Allston and Brighton. You don't want that headache.
Check these out if you haven't already -- Blue Heron Trail from Watertown Square runs EAST to Boston, and WEST to Waltham (and RT128). Minuteman Bikeway in Arlington heads EAST to Cambridge, and WEST to Bedford. These are both marvelous training resources.
Good luck in your search!
