Boston officials outlined security plans for the upcoming Boston Marathon Wednesday.
Mayor Marty Walsh held a news conference Wednesday afternoon with public safety officials and the Boston Athletic Association.
On Monday, the Massachusetts Emergency Management Agency held an exercise to make sure they are ready to respond to any potential situations during the race.
Last week, officials said there will be up to 5,000 law enforcement officers, enhanced checkpoints and dozens of surveillance cameras along the 26.2-mile route on April 18.
The Boston Marathon will be run on Monday.
Security has been stepped up significantly since the 2013 bombing killed three people and injured more than 260.
