Lisa Jones know all too well the havoc cancer can wreak on people's lives, and it was this that propelled her over the Kerikeri half marathon course.
Since the beginning of 2010 Ms Jones has lost her father, sister, and very recently, family friend 16-year-old Georgia Buckingham to cancer.
Her brother Craig is a survivor, while her mum has lived with leukemia for 13 years.
"Yes, I'm from a family of five and I'm the only one who hasn't had cancer," Ms Jones said.
"Apparently they are unrelated, but you do feel like a ticking time bomb sometimes."
