Overall I think NYRR did a great job. They started by sending out text and email alerts notifying runners the MTA metro card machines would be down and not accepting credit cards on the morning of the race. (This could have been disastrous). The expo was a little lackluster this year, from speaking to people who attended previously it was much smaller and not much to rave about. The shirts, from New Balance were OK!
Race day was quite a breeze, while rain was predicted, we lucked out and ran in perfect conditions. Lines for the restrooms (Portables) were very long, about 30 minutes in Wave 2. It was about 58 degrees at the start of the second wave, and didn't quite warm up much. The hills in prospect park, which are fairly long, but not too steep took a toll on me, but as you leav the park ( almost mile 7), the remainder of the race is flat and downhill. Running straight down Ocean Parkway, aid stations were plentiful and very well organized. The finish at Coney Island was exciting, crowds lined the course from about mile 9 and increased as you approached the finish.
I think the snacks at the end were a little blah, the goodie bag was a bag of pretzels, a green apple, a protein bar, Gatorade and water. This probably could have been a little better.

Hopefully, they'll do something to help the cell phone signals at the finish next year, Verizon had very little signal strength due to everyone trying to connect. Perhaps, they can get some type of wifi for the day next year.
The medal was beautiful and NYRR offered free engraving on Monday and Tuesday after the race...huge bonus for me.
