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

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

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

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

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

“Today we’ve given out shirts to all the runners, they come in with bibs and we give them a nice little green bag to actually take out to the race and run in, nice shirts to wear and you know just encourage Wish them luck until tomorrow and this is a great opportunity for a great race to run in Philadelphia is the best,” said Edwin Montoute, a volunteer.

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

“I think it’s supposed to be the biggest turnout I’ve actually had a couple of friends try to sign up and it was sold out,” said Jennifer Hui, a volunteer.

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

“I’ll do my best with a lot of carbs so you know you’re ready for tomorrow and enjoying 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,” says Gloria Vasquez of Kissimmee Florida.

It comes from 73-year-old Gloria Vasquez.

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

Here’s her advice for running at any age.

“Eat healthy, and I just love to run. I enjoy running,” Vasquez said.

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