A Boggabri woman is helping to kiss multiple-sclerosis (MS) disease goodbye by walking 50km to support a mother figure of hers.
Twenty-two year old Brianna Nelson is hoping to raise $1000 for MS research for Debbie Hobden, who is Brianna's "second mum".
"I've known Deb for over ten years ... she is literally my second mum and would do anything for me," Brianna said.
"It's very difficult to see her go through this, and anyone who knows her loves her as she is such a kind and giving woman. So I wanted to do this for her."
Brianna is completing the challenge through MS Research Australia's Kiss Goodbye to MS initiative, which aims to raise funds for MS research.
So far she has raised almost $540 and walked 30km, and aims to reach her targets by the end of May.
There are over 25,600 Australians living with MS, and there is currently no known cure.
