Around 48,000 runners participated in the ING New York City Marathon Sunday. One of the most popular marathons in the world, the race has been run every year since 1970, with the exception of last year's race, which was canceled due to Hurricane Sandy.

The streets of New York were lined with countless runners, wheelchair athletes, volunteers, spectators and residents to support the marathon. Most of the participants in the race were chosen to run via a lottery system. Among them were several celebrities. Many of the supermodels, actors/actresses and reality stars seen at the race trained for months in an effort to get in shape and run for charity. Whether they were running for their own charity organization or one they support in honor of a loved one, each celebrity finished the full 26.2 miles with pride.

Here is a list of some of the celebrities who were spotted running the marathon.

Christy Turlington Burns
The supermodel ran to benefit her organization Every Mother Counts, which she created to stop deaths caused by limited access to medical care for pregnant and birthing women. She posted a photo on Instagram while waiting at the starting line.

Sarah Reinertsen
The Amazing Race star ran to benefit the Challenged Athletes Foundation, which helps people who need prosthetic running feet, wheelchairs for playing basketball, handcycles and other special sports equipment. Reinertsen was the first female leg-amputee to complete the Ironman World Championship, and now she has the New York City Marathon under her belt as well. The Challenged Athletes Foundation posted a photo of the runner at the race on Twitter.

Joe Bastianich
MasterChef judge Bastianich ran for the Robin Hood Foundation, a charity with the intent of ending poverty in New York. At the end of the race, instead of stretches or an ice bath, Bastianich chose instead to go relax and have a beer. He posted a photo after the marathon on Twitter.

Bill Rancic
The Apprentice alum ran the marathon for Fab-U-Wish for his wife, E! News anchor Giuliana Rancic, who is a breast cancer survivor. Rancic got Timex to agree to donate $1 do the charity for every runner he passed on during the race. Rancic's wife posted a video of her husband running on Instagram.

Patrick Wilson
Film and Broadway actor Wilson ran to benefit the Michael J. Fox Foundation for Parkinson's Research. After the race, he took to Twitter to thank his fans for their support in the marathon.

Pamela Anderson
Anderson, who recently chopped her hair off to reveal a pixie cut, ran the race with her brother. She tweeted a photo with her brother Gerry, thanking him for running with her.

Sean Penn
Penn didn't run the race himself, but he did watch on the sidelines. He also sponsored five Haitian runners through his J/P Haitian Relief Organization. A photo on the organization's Twitter page pictured Penn with the five runners.
