Nassau County Executive Ed Mangano said that security is being reviewed for the RXR Long Island Marathon, which is scheduled for May 5. The race begins in Nassau’s Hub, in Uniondale, and winds through local streets before ending at Eisenhower Park in East Meadow.

“We are closely monitoring today’s tragic events at the Boston Marathon,” Mangano said. “The Nassau County Police Department is in constant contact with the FBI and New York City Police Department. Our patrol officers have been put on high alert. Our thoughts and prayers are with the victims of ... this horrific tragedy.”

Nassau County Legislature Presiding Officer Norma Gonsalves, who lives in East Meadow, said she planned to speak with Mangano and Nassau County Police Commissioner Thomas Dale prior to the marathon to ensure that all necessary precautions are taken. “We cannot always estimate everything that’s going to happen, but they have to be very proactive and make sure that every base is covered,” she said. “This is something that we cannot see happen here in Nassau County.”

East Meadow resident Todd Weinstein, who has run the Long Island Marathon’s half-marathon three times, said he was in shock as he watched the events unfold in Boston. “As a [runner], and as a supporter of the participants there, all you’re thinking about is the positives,” he said. “The hundreds of hours that have gone into training, the event, the spirit of it.

“The running community as a population is a very charitable population. We donate millions of dollars to be in these events,” Weinstein added. “People aren’t just running for themselves, they’re running for a charitable foundation … To take away the innocence of the event, it’s very upsetting.”

Jill Levine of Merrick, executive director of Forever 9: The Robbie Levine Foundation, said that the organization’s annual 5K Robbie’s Run, which begins and ends at Levy-Lakeside Elementary School in Merrick, will go on as scheduled on April 28.

“As always, we will work closely with the 7th Precinct to ensure the safety and health of our participants,” Levine said.
