When I ran this race it was pretty cold and the wait to the start was kind of long.
The scenery is impressive because you get to see the NYC skyline, you run in Time Square, and finish in Central Park.
I was expecting much more cheering (maybe it was too cold?) and some area were forbidden for security.
No pre or after party, they give you a bag with food and drinks, your medal, and you just walk away.
Expo is very minimal.
Overall it's not a very hard course, hilly because of a couple of bridges and Central Park hill.
