"Dad had three years with it before he passed but, when it came to diagnosis, it was a case of ruling every other possibility out before diagnosing MND," Ms Cadzow said. "We will never really know how long he lived with it before then."
She says the hardest part was seeing her father, who was once a huge sportsman, lose the use of his legs.
"With dad it attacked his legs first. He started by stumbling and losing his motion, so at first it looked a lot like he was drunk.
"That was the really degrading part."
For Ms Cadzow the extreme walk is a way to finally "do something for dad", and help other affected families feel like they are not alone.
"This is a way of letting them know they have support and do not have to face this alone. MND is an all-encompassing disease.
"To see your loved one go from a bright healthy person, to completely losing any sense of themselves can be so overwhelming."
The team are busy training for the walk which will leave Palmerston North on Friday, November 10 and arrive in Wellington on Sunday, November 12. Here they will join the Wellington Walk 2 D'Feet MND event.
"Some of the boys are in the gym on the treadmill in full breathing apparatus as we speak. They are going all out and I am completely blown away."
Each year over 100 New Zealanders die as a result of MND, with over 300 people living with the condition.
