(CNN) -- Paula Radcliffe will face a tough challenge from Salina Kosgei when she bids to clinch a third successive New York City Marathon title next month.
Paula Radcliffe will be aiming for her fourth New York Marathon title next month.
Race organizers have confirmed the participation of the world-class Kenyan, who claimed a thrilling victory at the Boston Marathon in the spring.
The 32-year-old, fourth in New York in 2005, currently looks the toughest rival in the field for Radcliffe as she seeks a fourth victory in the race.
Briton Radcliffe, who enjoyed her first triumph in the event in 2004, is currently recovering from a bout of tonsilitis which denied her the chance to chase a fourth IAAF World Half Marathon title in Birmingham last weekend.
Meanwhile, Robert Kipkoech Cheruiyot, who has won four Boston crowns, has also been added to the men's field for the race on November 1.
"Like all Boston Marathon winners, Robert and Salina are proven champions," race director Mary Wittenberg told reporters. "They will both be looking to join the elite few who have become champions of both races."
Kenya's former world marathon record holder Paul Tergat has withdrawn with an ongoing leg injury while Martin Fagan of Ireland will also be absent.
Jelena Prokopcuka is another who will not start the race around the five boroughs as the Latvian two-time champion is pregnant.
