21×21×21 Challenge

By Tom Murphy Join Me

In March 2026, I’ll be taking on a personal challenge by running 21 half marathons in 21 days, finishing with the climb up and down Mt Kosciuszko as part of the Rare Cancers Australia Kosci Challenge.

I’m doing it in memory of my brother, who should have turned 36 this year but will forever be 33, and my dad, who I lost to cancer earlier this year.

I’m running for them and for the thousands of families facing rare and complex cancers, where treatment options are limited and support can be hard to find.

Your donation will go directly to Rare Cancers Australia, helping provide practical, emotional, and financial support to people living with rare cancers, and funding advocacy that gives every patient a fair chance.

Every kilometre will hurt but it’s nothing compared to what so many families go through every day.

Thank you for being part of this journey, for every donation, and for every message of encouragement.

Thank you to my Sponsors
