World marathon record holder Paula Radcliffe believes she has put her failure at the Athens Olympics behind her after announcing on Tuesday that she will run in the New York marathon on November 7.

The 30-year-old Briton agonisingly dropped out of the marathon and 10,000 metres at the Games last August.

"Obviously, the scars will always be there," Radcliffe said from New York in a teleconference. "But it's behind me now and I want to enjoy myself and win the race."

After starting as favourite for the marathon at the Olympics, she pulled up in tears six km from the finish and later described it as the most traumatic experience of her life.

But Radcliffe won't be seeking redemption in New York.

"I accepted what happened in Athens although I am not happy about it," she said on Tuesday. "The pressure here is not different from any normal race I want to win."

Radcliffe will join a women's field including Olympic bronze medallist Deena Kastor of the United States, defending champion Margaret Okayo of Kenya and the world cross country long-course champion Benita Johnson of Australia.
