To expand on Pete's comment, a course can be renewed any time after expiration, up to the maximum date when the renewal would expire (20 years after original certification or Dec 31, 2011, whichever comes first - see renewal policy at http://www.usatf.org/events/courses/certification/renewal.asp ). For records, rankings, etc., the basic requirement ought to be that the course should have been renewed before the race. An expired course that hasn't been renewed isn't certified, so shouldn't be eligible for records.
