“The Biggest Loser” season 11 winner Olivia Ward and Kaiser Permanente Roseville Medical Center Physician-in-Chief Dr. Chris Palkowski led more than 250 people in a mile-long walk through Westfield Galleria at Roseville on Saturday.

The event kicked off the year-anniversary of Walk to Thrive, a program by Kaiser to encourage people to walk at least 30 minutes every day. After the walk, Ward did a Q&A session with the audience. Attendees also gained information on topics such as nutritious snacks, body composition testing and blood pressure screening.

Ward lost 129 pounds on “The Biggest Loser,” and has since been traveling around the United States to share her story.
