With tears in her eyes, pointing and shouting (with maybe a few colorful words thrown in), Flanagan won the race with a time of 2 hours 26 minutes 53 seconds.
An emotional Flanagan after her NYC Marathon win, the first by an American woman in 40 years. Kenyan Mary Keitany, who had won in NY in each of the past three years and set a world record in April, finished second.
In the men's race, Geoffrey Kamworwor of Kenya took first, his unofficial time clocking in at 2:10:53.
Mary Keitany of Kenya, the three-time defending champion, finished in 2:27:54, and Mamitu Daska of Ethiopia finished in 2:28:08.
"This is a moment I've dreamed of since I was a little girl", the 36-year-old Flanagan said.
Kamworor, who had finished second in 2014 behind Wycliffe Kipsang, was this time around the master as he broke away from among others Kipsang and Ethiopian Desisa Lelisa and Lemi Berhanu in the last three kilometers to win. "This is my first marathon victory".
The 2017 event was held just five days after a deadly Manhattan truck attack that left eight people dead. The race was described as a "very-well policed event, with many layers of security", said New York Police Department Chief Carlos Gomez. Flanagan's time is the second fastest time ever clocked by a USA woman in the race.
Keitany was seeking to cap a career year, in which she won the London Marathon with a blistering time of 2:17:01, a women's-only record.
In the men's wheelchair race, Switzerland's Marcel Hug completed an American clean sweep, crossing the line in 1:37.17 to add to his wins in Boston and Chicago this year.
