Flanagan dethroned Mary Keitany on Sunday and became the first American woman to win the New York City Marathon since 1977, potentially ending her decorated career with her first major marathon victory.
Flanagan's breakthrough came in the last career race for American great Meb Keflezighi. The 2009 New York winner collapsed at the finish line, his 42-year-old body pushed to its limit in his 26th marathon. Keflezighi finished 11th, about five minutes behind 24-year-old winner Geoffrey Kamworor of Kenya.
This may have been Flanagan's final race, too, although the four-time Olympian wasn't ready to commit. But she likes the idea of her and Keflezighi going out together.
"I was thinking of Meb, and I was thinking of how I wanted to make him proud," Flanagan said.
