The name Mary Lee will be forever etched in the minds and hearts of Niamh Lee and her family.
The pain of losing her 80-year-old grandmother - who died of cancer last October - is still raw at times for the 17-year-old who is committed to giving back to those affected by the disease.
She is now staring down the barrel of a 50km run - all in the name of fundraising for the Cancer Society.
On March 10, the Year 13 Havelock North High School student will compete in Triple Peaks; traversing Mt Erin, Mt Kahuranaki and Te Mata Peak - the same day as the Relay for Life.
"There are so many people out there with cancer and people have to watch their family and friends pass away and they can't do anything about it, and usually they shut off from the world," Ms Lee said.
