MT. PLEASANT, SC (WCSC) - It's the fifth largest race in the United States.
Race officials for the Cooper River Bridge aren't just dealing with a crowd control issue, they say it's security that will be placed at the top of the list.
To date, over 17 thousand people have already registered for the April 5th 10K.
Race Director Julian Smith says security concerns rose after September 11th, but have heightened "150 percent," after the bombings at last year's Boston Marathon.
"We will probably have every federal, state, and local agency involved," he said.
Officials are calling it a unified front, to include law enforcement from Charleston, North Charleston and the Town of Mt. Pleasant.
"The average runner will just notice that there are going to be more police."
Also different this year, will be the backpacks runners are allowed to carry. Registrants will receive a clear, mesh bag as the official race backpack, and are asked to leave any other bags at home.
Smith said there are more measures being taken, but will remain undisclosed to protect the safety of the event.
Sunday is the deadline to register for the Cooper River Bridge Run online, and receive the packet information by mail.
