Pam appeared on the Ellen Degeneres show, just days after running the New York Marathon, and explained that she had simply thought it was time for a change.

“I just thought my hair had had a life and I kind of wanted to put that behind me and start fresh,” Anderson said. “And I also thought it would be good for the marathon.”

The former Baywatch babe finished her first marathon in a respectable five hours and 41 minutes.

''And we raised a lot of money for our charity in Haiti,” she said. “My oldest son Brandon told me that next year he will do it with me.”
