We went to NYC to visit my son last weekend and did not pay attention of the weekend of Marathon in NYC. Yesterday - Sunday - they ran thru his area (a few blocks from the Barclay Center in Brooklyn NY) , one block behind apartment... Female Pros started at around 9:35 AM , then Men Pros start at around 10 AM... , then followed by all amateurs/non-pros. It was cold and very windy so I did not come out until around 2 PM and watch the Marathon (all amateurs/ non-pros at that time)... but it was very fun,... Loud music played along the route ... I am glad I did not know , otherwise I would stay home, avoid the crowd and missed the chance to see it "LIVE"... We got stuck there until after 3:30 PM when the police removed the blockages
