"I just want to let people know if I can do it, they can do it," Murphy said.
Last July, Extreme Weight Loss host Chris Powell surprised the Owensboro native on Local 7 Lifestyles where she was a regular guest on the show.
From there Sara went to boot camp where Chris and his wife Heidi helped her learn the ropes of working out and eating right. When she returned home, they still checked in to make sure she was staying on track.
"They are so genuine and hospitable. They just opened up their lives for us to come in and I felt like a part of the family," Murphy said.
She said they taught her about having accountability and making goals. One goal she never thought she'd realize: running a marathon. But, she did.
"Doing the marathon is something that no one will ever be able to take away from her. No one will be able to say it was given to her or people let her have it. It's something I did on my own and it's something to be proud of," she said.
With the many lifestyles changes, one of the biggest was her decision to leave Owensboro and move to Mesa, Arizona. She now works out six days a week doing Crossfit and other muscle-building exercises. She says her goal now is to build more muscle, run a marathon every year and keep on track with her weight.
" It's a struggle and one I didn't think I would be there but it's something that is going to be a battle the rest of my life," she said.
She said she knows this journey wasn't just about the weight and has a message for anyone out there looking to make a change.
"If you fall, pick yourself back up and do it then," she said.
