World record holder Paula Radcliffe says she could break the course record in today's New York City Marathon.

The 35-year-old Briton, seeking her fourth win in the 40th edition of the race, told reporters she was in good shape after a troublesome year which included foot surgery, hamstring problems and tonsilitis.

"I believe the course record can be beaten and I can run faster but the main objective is to win the marathon," said the defending champion.

Radcliffe, who set the world record of 2:15.25 at the 2003 London Marathon, will take aim at Kenyan Margaret Okayo's 2003 New York mark of 2:22:31.
