First Half-Marathon, Completed!

Valerie Bertinelli says that "I can't believe what a body can do if you believe in it," and she's taking that belief to new limits. Bertinelli teamed up with her longtime boyfriend Tom Vitale to ramp up her workouts, and her first half-marathon is now behind her.

Valerie made an appearance on the cover of PEOPLE after losing 50 pounds, and now she says she might complete a full marathon before she turns 50 next April.

"My legs are killing me, but I think I'm so high and excited and full of pride – which is an unusual thing for me! – that I probably won't feel it for a couple days," Valerie told PEOPLE after running her first half-marathon. Two years ago, Bertinelli weighed in at 172, but now she's 123 pounds and whizzing through workouts of running, sit-ups, and upper body exercise.

Bertinelli ran the Napa-to-Sonoma 13.1 mile race in 2:12:19, and told the press that she was going into relaxation mode for the rest of the weekend. She definitely earned it!
