At 71 years old, she ran in the Great North Run in September and on October 8, she completed the Yorkshire marathon.
Despite being a bit apprehensive with how she will go, she said she hoped to run the distance in under four hours.
"One way or another, I will finish. I always get nervous before a race."
Last week, she was planning to race in the Auckland Marathon, although in the week prior to that, Ted suffered a serious setback and was admitted to hospital, so she made the decision to withdraw.
"It's a shame I couldn't do the Auckland Marathon, but it is all about Ted. This is the final lap for the fundraising effort."
Now back at home in Patoka, he has to go to Hawke's Bay Hospital daily.
"I am so proud of Sally and her husband, Nathan for how bravely they are coping with Ted's illness."
She hopes to raise more than her target of $3000 and is already close to achieving it.
Ted's mum Sally said it is amazing what her mother was doing "especially since she only got into running later in life."
"We are all planning on going down. Ted's older brothers, Charlie and Oscar are also very excited to cheer 'Nanny Pam' on.
"I definitely want to acknowledge the work that Starship do and the renal team in particular. It is unbelievable the level of experience we have here in New Zealand for a relatively small country."
She said she hoped to "carry on what her mum had started" in the years to come, but with particular focus on the children's ward at Hawke's Bay Hospital.
