PHILADELPHIA (WPVI) — Philadelphia Marathon Weekend continues on Sunday with the big race, the AACR Philadelphia Marathon.

Now in its 31st year, this annual tradition offers runners the chance to take in some of the best views of the city. But for people driving through the city, this event usually results in serious traffic problems.

The city expects approximately 17,000 runners from our region and around the world to participate in the Philadelphia Marathon.

I’ve always heard it’s a great marathon, great crowd, great way to see the city,” said Brian Stull of Durham, North Carolina.

On Saturday, runners stopped at the Pennsylvania Convention Center to pick up their race bibs and other equipment.

“Today we gave out shirts to all the runners, they come in with bibs and we give them a nice green bag to take to the race and run in, nice shirts for them to wear and you know, just cheer them on good luck for tomorrow and this is a great opportunity, a great race to run in Philadelphia is the best,” said Edwin Montoute, a volunteer.

The race starts at 7 a.m. Sunday on Ben Franklin Parkway. Volunteers have been busy today making sure runners have everything they need to compete.

“I think this should be the biggest result. A few friends even tried to register and it sold out,” said Jennifer Hui, a volunteer.

After the race expo, the runners had plans to rest and refuel.

“I’ll do my best to eat lots of carbs so I know I’m ready for tomorrow and can enjoy the beautiful scenery of Philadelphia,” says Kerby Boulin of Hyattsville, Maryland.

But some say it’s all about the protein.

“I like to eat steak or chicken. Protein. I don’t believe in carbs. I don’t eat a lot of carbs,” said Gloria Vasquez of Kissimmee Florida.

That comes from 73-year-old Gloria Vasquez.

Sunday will be her first marathon in Philadelphia, but it will be her 94th marathon overall.

Here’s her advice for running at any age.

“Eating healthy, and I just love running. I love running,” Vasquez said.

More than 10,000 runners completed the Dietz & Watson Philadelphia Half Marathon on Saturday.
