Pamela Anderson ran the New York City Marathon on Sunday and has photographic evidence to prove just how brutal the aftermath can be.

The "Baywatch" babe joined Sean Penn's J/P Haitian Relief Organization team along with a slew of other people who ran the race Sunday to support residents of the poverty-stricken Caribbean country.

"Thank You New York City!," the "Dancing With the Stars" alum said, sharing a photo of a marathon medal and adding, "An amazing finish for #teamjphro at #ingnycmarathon. Keep supporting our work in Haiti."

But that isn't the photo that has us snickering with delight and simultaneously saying, "Awww!"

"Ouch!" the 46-year-old wrote, tweeting a photo of herself wearing a nightie while lying in bed with her face covered with a runners bib, ice packs on her leg and groin, and other marathon paraphernalia strewn around hair.

Well, 26.2 miles of endurance will do that to a person. And no matter how many beaches she ran across wearing a red one-piece on "Baywatch," running a marathon is no small feat.

Anderson, who ran the race with her brother Gerry, finished the race at a respectable 5 hours, 41 minutes, the New York Daily News reported, and suffered a minor leg injury during the marathon. She ran concealing her newly shorn pixie cut with a backwards baseball cap.

She also raised $75,914 as of Monday afternoon, and the team raised a collective $291,868, just a little more than half of the $500,000 goal that Anderson originally announced.

"People do things for other people that they wouldn't ordinarily do for themselves," Anderson said the newspaper when she started training. "Haiti is such a magical place. It has a real special place in my heart.... I have a lot of faith that I will be able to get through it. I'm committed. People tell me that I really don't know what I'm getting into, but that's kind of the story of my life. I'll just go with it."
