In this episode of We Need To Talk, Toni Street catches up with Newstalk ZB host and columnist Kerre Woodham.
In 2008, Woodham wrote a book about her first marathon, titled Short Fat Chick To Marathon Runner.
She was 40, overweight and depressed and decided to run a marathon to get her life back.
"I ran the first marathon with purpose, and ambition and a goal. The next five, I was kind of like ugh, how am I doing this? How did I get talked into doing another one?
"My last marathon was six years ago, the year I turned 50, and I'd never been more fit, more fabulous, more focused, and then: life."
