Smokin' Aces Motivated Alicia Keys to Run Marathon  1/23/07

Singer/actress Alicia Keys loved her intense training regime for the film Smokin' Aces so much, she decided to keep working out and train to run a marathon in Greece.

The Fallin' singer makes her big screen debut in the film playing a tough hit woman out to kill a sleazy magician played by Jeremy Piven.

She explains, "It kind of started with Smokin' Aces, because I was training in a way that I'd never trained before.

"I just kind of woke up and thought, 'I want to run a marathon.'

"So we started preparing for it and I did! It was the weirdest sensation. It was pretty long - it took me five hours!"
