Marathon Data Base

The MarathonGuide is a data base of marathon races around the world. Not only does it provide access to upcoming marathon races but it also provides information about past marathons. It seems to go back only to about 2000 but it had to start somewhere. You can find past results. All finishers and their times are posted for most races. There are also links to articles about running marathons. You can search for marathons by location or by dates. Once you find the marathon you are looking for you can view results from many of the marathons and search by name or even by time of finish.
