I just noticed that Arne has posted the Boston course in our group's Maps section. If you're interested in seeing what we're shooting for, check it out! Along these lines, I'm thinking that it could be a good idea to put in maps of the other marathons I've done (Buffalo, NYC, and Steamtown), as well as ones I'm considering (Ocean Drive, Pocono, God's Country, Lehigh, and Northern Central Trail). Not only because I like maps, but also so I can directly compare the elevation profiles. Cheers, Carl
