Aselefech Mergia, the three-time Dubai Marathon champion and Buzunesh Deba, who has twice finished second in New York are seen as the two threats to Keitany's expected great achievement.
Other Kenyan women in the race include Joyce Chepkirui, third in Boston this year and Sally Kipyego, the 10,000m silver medallist from the 2012 London Olympic Games.
After a disappointing performance at the Rio Olympic Games, Stanley Biwott will be seeking to bounce back to the spotlight by defending his title in the men's race.
Biwott's personal best time of 2:03:51, which he achieved after a spectacular race with Eliud Kipchoge during the London marathon earlier this year is -by over one minute- the best time against those of other elite athletes toeing the start line.
Lelisa Desisa, Ghirmay Ghebreslassie, Lucas Rotich, Dathan Ritzenhein and Moses Kipsiro are some of the top athletes expected to provide a tough competition to Biwott.
