On Tuesday, Metro police along with other law enforcement agencies and race officials outlined their security plan for Saturday's Country Music Marathon.
Metro Police Chief Steve Anderson stressed that there is no known threat to Nashville or the marathon.
Police officers and security workers will be very visible along the race route.
Law enforcement are also encouraging the public if they "see something" suspicious or concerning to "say something."
"We're calling on everybody, all the runners all the spectators to mind your own belongings, just as you would if you were in an airport," Chief Anderson said.
Metro police said they will also have a zero tolerance policy and make arrests on site if needed.
Chief Anderson added, "We will not tolerate any pranks, or mischievous type behavior or any attempt to disrupt the marathon or cause any runner or spectator any fear."
In 2012, more than 350 Metro police officers and supervisors were involved in staffing the event.
The annual Country Music Marathon is set for Saturday morning. Each participant will receive a wristband in honor of the tragedy at the Boston Marathon.
Runners will also experience a change in security. This year, runners will be given a clear plastic bag to store their belongings during the race.
"It will give us a better chance to see that bag and anything that may be in it, and we will have security at every gear check truck also monitoring the bags as they're handed off," Adam Zocks, Vice President of the Competitor Group, Inc said.
A special telephone line will be operational Saturday morning for citizens to specifically report any marathon-related suspicious activity. The number is 615-880-1515.
