Runners from the woman's elite division run as New York City Police Department officers watch in the Williamsburg section of the borough of Brooklyn during the New York City Marathon in New York, November 3, 2013. In addition to cheering supporters, runners in this Sunday's New York City Marathon will also be monitored by bomb-sniffing dogs, police scuba divers and surveillance helicopters to prevent an attack similar to the one at the Boston race earlier this year.
