Metro Police wouldn't provide details about the number of officers who will patrol the streets during the race. Race Director Stephanie Kirby says approximately 20 officers will secure the perimeter of the race. A dozen more will patrol the race with a bomb-sniffing dog.
Metro says some of its officers will be in plain clothes, ensuring nothing suspicious takes place.
Because of the Boston bombings, Kirby said race organizers appointed a security liaison to work with Homeland Security, Metro and other security units. They want to ensure nothing out of the ordinary happens.
"There is no visible threat at all. The Homeland Security team is well aware of what's going on in the community, and they've been able to alleviate some of those concerns that we had in light of Boston," Kirby said.
Along with the extra help, police ask runners and attendees to keep their eyes open. They ask people to remember the "If you see something, say something" public awareness campaign used by law enforcement.
