"Fast and flat"

If you tried to qualify for Boston 2008 but missed the qualifying time (or you want to qualify for guaranteed entry into New York 2008), check out this analysis of Boston qualifying times. Among other useful pieces of information, it lists the dozen or so certified US races that had the highest number of qualifiers for 2006 and 2007. Presumably this data indicates that their courses are both “fast” and “flat” — good candidates for your next attempt.
