Mayor To Marathoners: 'You're Going To See The Most American Of American Cities'

CHICAGO (CBS) -- Mayor Rahm Emanuel said "the world will watch the endurance of the human spirit" at Sunday's Chicago Marathon - the first major marathon after last spring's bombings in Boston.

Emanuel had one request of the 45,000 runners.

"If you get a chance, look up. Look around. You're going to see the most American of American cities," he said.

Emanuel talked about the city's preparations.

"Post-Boston - while we will do our job so everybody can enjoy and have great fun, the fact is that people coming back - we had a record number last year. We expect a record number of people running this year. And the world will watch the endurance of the human spirit to persevere," he said.

The mayor said it will amount to the entire country -- and the entire world -- coming together to say we will not be deterred.
