We are just hours away from tens of thousands of runners taking to the streets of Chicago in the 44th Bank of America Chicago Marathon.

The event is attracting runners from all 50 states this year and more than 100 countries.

People packed into Italian Village Restaurants in the heart of the Loop Saturday night for a massive carb intake.

"We make sure we load up on plenty of pasta, plenty of bread. We know what we're serving today," said Jared Gelvand, Italian Village Restaurants' wine director.

Runners are conserving their energy for Sunday and focusing on the carbs -- lots of carbs.

"I ran it last year for the first time just to see it and now this year, I'm actually trying to do a really good time," said Daniel Tenayuca, a runner from Algonquin, Illinois.

While for many this isn't their first marathon, it's one they wanted to check off their list.

"This will be my first full marathon. I've done a number of half marathons and other races and other distances, but spent the summer training for this," said Tim Todd, a runner from Kansas City.
