I pulled up quite a few of them last night and put them into HuffPost, pretty amazing to see where runners go in these major cities. For the U.S. cities I've been too -- among them Boston, NYC, DC (of course) and San Francisco, I can see why the routes are so popular. DC, for instance, gets a tonne of runners who do loops of the two-mile long Mall.
Hope they add Canadian cities in the near future. Here are a bunch of the screenshots, but see the rest here.
|NYC: Central Park the running zone|
|DC: Mall and Rock Creek Park/Potomac Trail|
|Chicago waterfront rules!|
|Boston: Along the Charles.|
