I'm Riding For

In memory of Arlene Mulder Papaioannou and all the kids still fighting cancer

This years ride is in memory of my daughter Arlene, who lost her fight in a battle against colon cancer in October 2018💔! While she was no longer a child, she was MY child! . Please help me to reach my goal of $15,000 or more this year. I’m trusting that I can count on your support again this year....will YOU be the one that pushes my numbers over the top? You sponsor and I will do the biking!

My Story

21 Sep 2025

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

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.

My ride in 2023, 2024 and 2025 have surpassed my goal of $15,000, so my starting goal for next year will be $15,000 again and will be adjusted as needed! I continue to bike in memory of my daughter Arlene, and riding and fundraising for all those still in the fight. I am hoping that you will continue to support me by sponsoring. YOU SPONSOR AND I WILL DO THE BIKING! Please support me by making a donation to give these kids the brighter futures they deserve.

Please check out my previous years stats in the sidebar on the left bottom of the page....$185,490.05 and counting, over the last nine years! YOU all helped me achieve that, and for that I am forever grateful!

Your support will change little lives.
