The bombing that took place in Boston Monday, begs the question: how safe are the events closer to home?
"You're sickened and saddened by what's going on," said Myrtle Beach Marathon Race Director Shaun Walsh, describing what it was like to watch the events on television.
He explained Monday's events are forcing him to re-evaluate a crisis management plan for next year's race in Myrtle Beach.
"We'll sit down the law enforcement and review our policies and procedures and through crisis comes change and I think we'll also be able to modify our policies again," said Walsh.
Unlike so many other sporting events, which are closed off in arenas, a marathon is one of few events open to the public and completely free.
Walsh said the race can have 15,000 spectators lining the course and the race's finish line can see more than 5 and a half hours of activity on race day.
"Our finish line is a little more unique in the sense that it's a little more closed in one respect because we do finish at the baseball field so it's not out on the open street, however, anyone can come in and view the event anyway," he explained.
But Walsh said before they evaluate their own procedures for next year's race, they want to hear what happens with the investigation in Boston.
"We're always trying to make our event better and at the forefront of that is we're always trying to make our participants and our spectators and our volunteers to have the safest possible event we possibly can."
