The New York City Marathon’s security procedures will remain similar to last year’s measures.

The 2013 race was the first since the bombings at the Boston Marathon. The only notable change from last year will be adjustments to how entrants are screened when they arrive at the start in Staten Island, in an effort to reduce delays, New York organizers said Monday.

About 50,000 runners are expected for Sunday’s race.

The 2001 marathon took place less than two months after the Sept. 11 attacks, so security has been heightened ever since. It was tightened even more in 2013.

Barriers were erected around Central Park, where the race ends. Spectators could enter only through a few designated checkpoints where bags were searched.

On Sunday, the NYC Marathon will have the millionth finisher in its history. That lucky entrant will win guaranteed entry into the race for life and a shopping spree for marathon gear.

Going into Sunday, 974,257 people have completed the 26.2-mile course. The millionth runner to cross the finish line will probably complete the race in just over four hours.

Julissa Sarabia of Queens was the race’s millionth starter last year, which was her first marathon. She didn’t plan to ever run another, but when she earned a guaranteed entry into this year’s event, she changed her mind.
