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

3 May 2026

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. Let that sink in for a minute......1700 every year. While, unfortunately, some of those kids will NOT survive their cancers, but many do but remain in treatments. Then, the next year, and every year thereafter, another 1,700 kids are added to that. I have a friend in the GCC community who rides in memory of her baby sister, who passed away 56 years ago......that's 56 times 1,700 minus the ones who succumbed to the disease. That's a LOT of kids, and requires a lot of money.....THIS IS WHY WE RIDE AND FUNDRAISE!

Kids should be living life, not fighting for it.

My rides in 2023, 2024 and 2025 have surpassed my goal of $15,000 each year, so my starting goal for this 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....$189,395.05 and counting, over the last nine years! YOU all helped me achieve that, and for that I am forever grateful!

This will be my last year doing this challenge, so I am really hoping to finish strong this year, but for that to happen, I need A LOT of support!

Your support will change little lives.

10.1 km ride - GCC 2026 - Day 26 - Wednesday, August 26, 2026

GCC 2026 -Day 25

25 Aug 2026

I am nearing the end of my time with GCC, and people have been asking what I am going to do with my time!

Well, first I have to finish cycling to honour my commitment to ride 300 kilometres during the month of August. After that, I have another little project I would love to get started. ❤️

Over the last 10 years, I have been incredibly blessed by the support of so many people. I dare not start mentioning names because I know I would miss someone, but if you donated, provided prizes, encouraged me, shared my Facebook posts, rode with me, or supported me in any way, please know how grateful I am.

Over those 10 years, I have also been honoured by Great Cycle Challenge Canada to be called a Champion, and year after year they have generously supplied me with GCC jerseys and T-shirts.

Now, as my GCC journey begins to wind down, I have been wondering:

What am I going to do with all these jerseys and T-shirts?

They could sit on a shelf or in a drawer for the next 20 years.

But I have a much better idea. 🧸❤️

I would love to turn them into comfort bears for children on a cancer journey.

These jerseys represent 10 years of my passion for helping kids fighting cancer. Instead of packing that passion away, I would love to pass it along.

My passion can become YOUR passion to help kids fighting cancer!

And that is how the Great Henrietta Bear Brigade was born! 🧸

I have 19 GCC jerseys and 7 T-shirts ready to become bears. Now I need some help.

I am looking for people who can sew and make memory bears, and I am also looking for people who would be willing to sponsor a bear to help cover the costs of making the bears and getting them to children at SickKids Hospital in Toronto.

Together, we can turn 10 years of memories into hugs, comfort and smiles for little warriors who fight so hard every single day.

And with September being Childhood Cancer Awareness Month, I can’t think of a better time to get this brigade started. 🎗️

If you can MAKE A BEAR or would like to SPONSOR A BEAR, please reach out to me so we can talk about how to make this happen.

LET’S DO THIS! 🧸❤️

Join the Great Henrietta Bear Brigade!

One jersey. One bear. One hug.

Together, we can make a difference

GCC 2026 - Day 22 Group Ride

24 Aug 2026

Wow, it’s been ten days since I updated this page! I’ve been trying to get a ride in every day but then did not find the time to update the page. Yesterday was special though! After much planning, making sure all the moving parts were in order….dot the “I”s and cross the “t”s so to speak! Everything looked like it was perfect. Unfortunately, the only thing I had no control over was the weather. After watching the weather network all week, it looked like it would be a good day to ride! Then as the day grew closer, Mother Nature thought to throw a wrench into all the planning…forecast for rain for a good part of the morning! What to do - should we cancel, should we ride? A good downpour in the morning dampened my spirits for sure, but let’s soldier on. It’s what the kids on a cancer journey have to do!!! Thoughts about postponing were not really an option….too many moving parts in this special day to be able to do later, so off to Tillsonburg I headed! What happened was truly amazing, the roads dried up, the sun came out, and together with 16 other riders from various parts of the province, set off on our ride! After the initial meeting and getting acquainted with new riders to the group, and some drone video by Craig, we were piped from the parking lot of the Alliance Church parking lot to the road by Stephen, we cycled 14.5 km. We were kept safe with the help of John, from Cops and Rodders Oxford Branch, who provided a sweep car to follow the group. Unfortunately, the unpredictable weather meant we had to resort to Plan B, and use his own car instead of the cool hotrod we were planning to make use of. At one point we lost part of the group and sent back a "search and rescue” team to catch them up to where we were waiting for them. We continued on to Makkink’s Flower Farm and Bakery for more pictures and a wonderful time of getting acquainted, sharing stories and experiences of being part of Great Cycle Challenge! It was such a special time, made even more special by having our injured friend, the unicyclist, Zach Wells in attendance!! These are some of the experiences and friends that I am going to miss since this is my last year with Great Cycle Challenge, but these memories will stay with me forever! I’m sure I will stay in contact with many of you, and follow your progress as you continue to ride and fundraise for the kids fighting cancer!

“Thank you so much Albert and Nelly for your continued support for this cause that is dear to my heart. Tomorrow would have been Arlene's 57th birthday, so definitely a more emotional day for us. I am gad Nelly is enjoying the "throw" everyday! I am trying to think of something creative to offer this year, but so far have come up empty.....I am running out of ideas I guess, although I suspect most people donate for the cause, not the prize! Take care and make sure you connect the next time you are out this way!”
