Jennifer Lopez brings Good Morning America along as she trains for a triathlon this October.

“It actually came up when I was about eight months pregnant, and I was beached… like a whale, and I was watching TV and I saw a triathlon and I said, ‘You know what? I think I could do that. That would be great for me to do, maybe I’ll do it this year,’” Jenn told GMA. “Everybody told me I was crazy.”

The new mom of two was selected the “Most Inspiring Woman of 2008″ in the September issue of Self Magazine.
