Jennifer Lopez is competing in the 2008 Nautica Malibu Triathalon and appeared on ABC's Good Morning America today to talk about how she was inspired to enter the grueling 22.5 mile event.
Jennifer Lopez appeared on ABC's Good Morning America in full workout gear  in Central Park. Lopez has been in triathlon training to raise money for a charity.

"The idea came up when I was about eight months' pregnant when I was beached like a whale. I was watching TV and I saw a triathlon, and I said, 'I think I could do that. 'That would be great for me to do. Maybe I could do that this year.' And of course everybody told me I was crazy."

Lopez is being assisted in her training by Self Magazine editor Lucy Danzinger and is going to attempt to swim a half mile, bike 18-miles, and run 4-miles on September 14th. She is raising money for the Children's Hospital here in Los Angeles and you can help by donating at Self.com as well as get updates on her progress.
