My Story

2 Oct 2026

This October, I’m riding for hope, courage, and every child fighting cancer. 🚴💙

This marks my fourth year taking on the Great Cycle Challenge to help give kids the future they deserve.

Childhood cancer remains the leading cause of death by disease among children in Australia. Every child diagnosed is one child too many. No child should have to fight for their life.

💛 This year’s ride is especially personal.

I’m riding in loving memory of my sister, Sharmini Ratnasingam, who we lost to cancer this year.

Every kilometre I pedal will carry her memory with me — her smile, her strength, and the love she gave our family.

Every kilometre I ride and every dollar we raise will support the Children’s Medical Research Institute, helping fund vital research to better prevent, diagnose and treat childhood cancer — and ultimately find cures.

These kids are warriors, but they shouldn’t have to be.

🙏 Please join me in this fight. Every donation, big or small, can help bring us closer to a future where cancer no longer steals childhoods, dreams, or precious time with the people we love.

For the kids fighting today.

For the hope of a cancer-free tomorrow.

And this year, for you, Sharm. 💛

Together, we can help save little lives. 💙

Thank you from the bottom of my heart for your support.
