NEW YORK (AP) -- American Meb Keflezighi, the 2009 New York City Marathon champion, will compete in this year's race less than three months after finishing fourth at the London Games.

The 2004 Olympic silver medalist also committed to run New York in 2013, when he will be 38.

This year's NYC Marathon will feature all three U.S. men who raced in London, with Ryan Hall and Abdi Abdirahman joining Keflezighi in the field. Hall and Abdirahman didn't finish at the Olympics because of injuries.

The NYC Marathon is Nov. 4. It will have a new $100,000 prize purse for American runners, with the top man and woman receiving $20,000.

Three years ago, Keflezighi became the first American since Alberto Salazar in 1982 to win New York.
