Runners make their way up 1st Avenue in Manhattan during the 2011 ING New York City Marathon in New York November 6, 2011. The 26.2 mile marathon course is through the five bouroughs of New York City and is one of the largest in the world.

On Sunday, Nearly 50 thousand distance runners are scheduled to run in the 43rd New York City marathon.

It is one of the largest events of its kind in the world with close to 47,000 people expected to participate. However, the hurricane out East has forced officials to change some plans and there is worry that many runners from overseas may not be able to reschedule flights in time for the race.
