Actress Kirstie Alley is determined to shed the pounds and get in shape so she can take part in a triathlon.

The former Cheers star has gained back all the weight she lost while she was a spokeswoman for diet company Jenny Craig back in 2007, and now she's fighting to get thin again. And Alley is aiming to be fighting fit so she can achieve one of her personal goals.

She tells People magazine, "One of the things I want to do is do a triathlon. I've been researching it, and I might want to do my first triathlon in Italy. It's a two-mile swim, a 12-mile bike and a three-and-a-half mile run. I was a competitive swimmer, so I think the swimming will come back to me really fast."

Alley will join a host of stars who have taken on the challenging race - Jennifer Lopez, Matt Damon and Matthew Mcconaughey have all completed the grueling competition in the last year.
