The team honour the memory of Sandy Adams, who lost her two-year battle with brain cancer last August.
It is the third year the team have taken part.
They walk to raise awareness and much-needed funding for research to find a cure so no other family has to suffer as they have.
Sandy’s husband John said his wife endured surgery, radiation and months of chemotherapy.
‘It was a total shock that shattered our family,’ he said.
‘She was the most positive and inspirational person, who never gave up hope of beating this.
‘She was only 55 when she succumbed to this terrible disease.’
Mr Adams said his wife was the most generous, kind and loving person who was always there to help others in need.
‘She walked with us at our first relay in 2011 and ran in the HBF Run for a Reason to support team Cracking the Cure just a week after finishing another round of chemo,’ he said.
‘Her only concern was for her girls and me and how we would deal with this.
‘This was the reason for her absolute positive attitude and focus on beating this disease.
Relay for Life is a community event, raising funds and awareness on behalf of the Cancer Council WA.
