I am always moved by the NYC Marathon and generally make a point of watching it in Park Slope.

Here’s a nice marathon map from the Brooklyn Paper.  Brooklynites can see the runners run on Fourth Avenue starting in Bay Ridge. The Brooklyn Paper has the approximate times when the lead runners and then the rest arrive in each nabe.

I always think Third Street and Fourth is a great spot to watch (the
lead runners will get there around 9:40 and the rest around 10:10).

It’s about 6 miles into the race and the runners still have a lot of energy and joie de vivre.

But the runners also run through Forth Greene, Williamsburg and Greenpoint.
