Running groups in Seattle

A co-worker was asking about training for a half-marathon so I figured I would put together a consolidated list of running groups in Seattle and on the East Side.  NW Runner magazine has the most comprehensive list of weekly runs that I have seen.  The current list is at http://www.nwrunner.com/calendar/05-07.html.  If that gets to be out of date, you should be able to find an updated one in the Community --> Resources area on their site.  Some specific groups that I have run with:
