SALT LAKE CITY (AP) — Organizers of the Salt Lake City Marathon are meeting to review security for Saturday's event. Marathon Director Steve Bingham says it's the number one topic on the agenda for a meeting Tuesday that was scheduled before the tragedy in Boston.

He tells the Deseret News, "It's on everyone's mind, and rightly so." Fraser Bullock, who was Utah's chief operating officer in the 2001 Winter Olympics, says Monday's bombing was an event organizer's worst nightmare. He says securing a 26-mile route is a formidable challenge because it's hard to establish a secure perimeter around such a large area.

He says the key to success at the Olympics in Salt Lake City was law enforcement intelligence. This weekend's event at Liberty Park is expected to attract 7,000 to 10,000 participants.
