My Story

9 Aug 2026

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

Why? Because right now, over 1,700 children are diagnosed with cancer every year, and it's the biggest killer of children from disease in Canada.

Kids should be living life, not fighting for it.

So I am raising funds through my challenge to help these kids and support SickKids Foundation to allow them to continue their work in developing treatments and finding a cure for childhood cancer.

Please support me by making a donation to give these kids the brighter futures they deserve.

Your support will change little lives.

Thank you.

I barely have the energy while working nights but every km I put in is a decision I'm making for the kids that don't get to make that choice themselves. We can all kick Cancer's butt together! Thank you!”

    “I hope you're right haha. But the pain in my a** is nothing compared to the pain of losing a child to cancer, and the struggle to put in each km is nothing compared to the battle every child with cancer has to go through every day! Together we can do so much!”
