This year, she has already won her third career London Marathon in April, breaking the women's only marathon record in a blistering time of 2:17:01.

Keitany won the New York Marathon each of the last three years, including a dominating performance last year in which she finished the course on a solo run in 2:24:26. Her 3:34 margin of victory was the greatest in the women's race since 1980, and she became the first able-bodied runner since Grete Waitz to win the event three years in a row.

"Another top finish for Mary would give her the second most titles in the event after Grete Waitz," said Peter Ciaccia, New York Marathon director.

"I'm so excited to return to New York to race for my fourth consecutive title," Keitany said.

"Being among the all-time leaders in New York is truly an honor, and while it will not be easy to defend my title, surpassing a legendary runner like Paula Radcliffe for the second-most victories by a woman in the event would be incredible."
