My Story

2 Oct 2026

This October, I am taking part in the Great Cycle Challenge to fight kids' cancer!

Because cancer is the largest single killer of children from disease in Australia. Right now, 90 children are diagnosed every month, and sadly, 3 die every week.

Kids should be living life, not fighting for it.

And so I am riding and raising funds to support the Children's Medical Research Institute to continue their work into the prevention, diagnosis, treatment and finding a cure for childhood cancer.

Please support my challenge by making a donation through my fundraising page to give these kids the brighter futures they deserve.

Together, we can save little lives.

Thanks for your support.

Nikki
