Paula Johnston before her transformation March 2015
When she first began running she used to hide her face with a hoodie and sunglasses.
"I was still you know 130kg and I thought I looked ridiculous."
Now drivers honk their horns and shout words of encouragement.
"That feels really cool."
She remembers clearly the moment she decided to turn her life around almost exactly one year ago.
"I never looked in the mirror I didn't like what a saw but I caught myself one day, and I just thought 'look at what you've become, you can't go on like this'."
Paula Johnson's amazing before and after results.
She began by doing a series of body weight exercises.
"I lost some weight that way but I plateaued."
Then she saw a Facebook post about the trip to China by motivational couch Doug Healy.
"I saw the call out and I thought 'wow that's me, that's what I need to do'."
