I'm Riding For
Christine Hiemstra
Christine, my mom, was diagnosed with melanoma in 2015. Sadly she lost her battle on June 17, 2024. This year I will be not only cycling for all the kids and their parents, but also for Mom.
My Story
This August, I’m participating in the Great Cycle Challenge to fight kids' cancer.
Why? There are three key reasons:
- Over 1,400 children are diagnosed with cancer each year in Canada, and it remains the leading cause of disease-related death among children.
- While we lost our baby girl Evelyn to a different cause, I can deeply understand the fears and heartache of losing a child.
- My mother was diagnosed with melanoma and tragically lost her battle on June 17, 2024.
This year, I will be riding in honor of all the kids, their families, Evelyn and my mom.
Kids should be living their lives, not fighting for them.
This will be my fifth year taking part in this incredible challenge. This year, I’ll be riding along the Guelph-to-Goodrich (G2G) Rail Trail, reconnecting with old friends and making new ones. I invite you to join me! Every Saturday in August, and the last week of the August, I will be riding the 132 km G2G trail. On my final day, I’ll complete the challenge with an epic 260 km ride—end to end... and end to end, along the entire trail.
I’m raising funds to support SickKids Foundation in their efforts to develop treatments and ultimately find a cure for childhood cancer.
Please consider supporting my ride by making a donation to help give these children the brighter future they deserve. As a thank you:
Anyone who joins me for a ride will receive a customized, handmade wooden medallion. And all those who donates $200 or more will receive a special thank-you gift from On The Mark Laser Engraving (www.onthemarklaser.ca). More details to come.
Additionally, to show my gratitude for donations of $100 or more, we’ll be hosting an All-You-Can-Eat Rib & Chicken BBQ on Saturday, September 6. We’ll also be handing out awards to those who donate $200 or more.
Thank you for your support. Your generosity will make a difference in the lives of these children.
