Active.com has this list of the top 10 American running cities. I'm more than a little miffed that New York and Chicago beat out my hometown of DC (and my surrogate hometown of Indy isn't on the list -- but that's not a surprise).
Of course, the list is comparing apples and oranges. No offense, Ted, but in what world is New York a better running city than Eugene and Boulder? They are simply incomparable.
Anybody up for creating our own lists? First: greatest running college towns. I know one of these well and I'm enough of a running history buff to name two others -- Boulder, Eugene, and Gainesville. Not necessarily in that order, but it seems a good start. Others?
Second: greatest marathon cities. Relevant factors include (1) size of major race, (2) local support for major race, (3) number of minor races, (4) variety of attendees at the various races, (5) undefinables, like history or screaming college students at Mile 13. My sphere of acquaintance is pretty small, but I go Boston, DC, Dublin -- realizing full well there are cities (including, of course, London, Chicago, and New York) that fit before and between those selections.
