I'm Riding For

Christine Hiemstra

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

18 May 2026

This August, I’m participating in the Great Cycle Challenge to fight kids’ cancer.

Why? This cause is deeply personal to me.

More than 1,400 children are diagnosed with cancer each year in Canada, and it remains the leading cause of disease-related death among children—something no family should have to face. While we lost our baby girl Evelyn to a different cause, I understand the fear and heartbreak of losing a child. My mom also passed away from melanoma on June 17, 2024.

This year, I ride in honour of these children, their families, Evelyn, and my mom. Kids should be living their lives—not fighting for them.

This is my sixth year in the challenge. Throughout August, I’ll be riding the Guelph-to-Goderich (G2G) Rail Trail. I invite you to join me! I’ll ride every Saturday and during the final week, completing 132 km rides, with a final 260 km end-to-end ride to finish.

I’m raising funds for SickKids Foundation to support better treatments and a cure.

Please consider donating. As a thank you, anyone who rides with me will receive a handmade wooden medallion.

We’ll also have prize draws in June–September, plus extra prizes on Kick Cancer’s Butt Day. A $25 donation earns one ballot. Prizes include a charcuterie board, 3D-printed games, a family pass to Clovermead Adventure Farm, and more.

Donors of $100+ are invited to an All-You-Can-Eat Rib & Chicken BBQ on September 19th.

Thank you for your support—your generosity makes a real difference.
