In Memory of Walter Marescia

Riding the MACA Cancer 200 this year is deeply personal for me. I’m riding in memory of my grandfather, Walter Marescia, who passed away from prostate cancer in 2022. This ride isn’t just about the kilometers, it’s about honoring a man whose strength, kindness, and quiet determination shaped my life in ways I carry with me every day.

Walter wasn’t just my grandfather; he was my father figure and a true pillar of strength in my life. He showed up, stood firm when things were hard, and taught me what it meant to keep going with grace. His resilience in the face of illness, and the love he gave so freely, continue to inspire me, especially on the toughest stretches of the road.

As I pedal through the MACA Cancer 200, every kilometer  is for him, and for the countless families affected by cancer. This ride is my way of remembering Walter, honoring his legacy, and supporting the fight against a disease that took so much from so many. I ride with gratitude, purpose, and his strength at my back.

I’m on a mission to defeat cancer.

Cancer doesn’t just affect one person, it shakes up families, friends and communities. This year, I will be taking a stand against it. 

In October 2026, I’m joining a community of passionate riders to cycle 200km to raise vital funds for cancer research at the Harry Perkins Institute of Medical Research.

Every dollar pushes us closer to breakthroughs at the Perkins where brilliant researchers work tirelessly to find life-saving answers for some of the toughest cancers. But they also need our help to ensure their vital progress continues– no matter what.

 100% of the funds we raise will go back to the Perkins giving cancer researchers the support to continue their life-saving work so that our loved ones can live longer, healthier lives.

The Ride is more than just a test of endurance—it’s about unity. I'll ride alongside an incredible group of people who believe, as I do, that cancer can be conquered. Your support can turn this belief into reality.

I can’t do this alone. Will you help me to reach this goal?

Whether you join me on the Ride or support my fundraising, your generosity could be the key to saving our loved ones from this disease.

Together, we can beat cancer!
