Pamela Anderson will run the 2013 New York City Marathon on behalf of J/P Haitian Relief, a charity founded by Sean Penn to help victims of the 2010 earthquake in Haiti.
Anderson, 46, is a vegan animal-rights activist who has worked with PETA for over 14 years. The longtime workout fanatic and former fitness trainer has never run a marathon, but is up for the challenge.
"I've never taken on a physical challenge like this but I am willing to do something to show my dedication," Pamela told ET Aug. 28. "It is incomparable to the struggle [Haitian] people face."
Pamela will team up with five elite Haitian marathon runners on behalf of her "Long Run for Haiti" campaign: Astrel Clovis, 43, Petrus Cesarion, 31, Jean Macksony, 27, Bertine Laine, 31 and Carline Lamour, 21.
Amazingly, the super-fit mom of two has maintained the same sizzling bikini body that made her an international sex symbol on "Baywatch" 24 years ago. Anderson's former co-star David Hasselhoff, 60, has also aged well, thanks to a healthy diet and daily workouts.
The buxom 5-foot-7 Anderson has been a vegetarian since her teens, and has long been an advocate of weight-training and calisthenics. Pamela, who switched to a vegan diet several years ago, has credited the plant-based eating plan for helping her manage Hepatitis C, a condition she has had since 2002.
"I have Hepatitis C and I feel great, which I think has a lot to do with my diet," she said in 2010. "I feel better [following a vegan diet]. I always feel healthy."
While some are skeptical that a vegan diet can adequately fuel endurance training such as a 26.2-mile marathon, it bears noting that some endurance athletes have experienced great success on a plant-based diet. Ultra-marathoner Rich Roll lost 50 pounds, kicked a longtime drug and alcohol addiction, and completed several triathlons after switching to a vegan diet.
More recently, exercise-physiology instructor Josh Garrett walked a record 2,655 miles in two months (averaging 45 miles a day!) powered only by vegan bars, peanut butter, kale chips and corn nuts.
The 2013 New York City Marathon takes place Nov. 3.
