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.

    14 Jun 2026

    🚴‍♂️ Welcome to the 2026 Great Cycle Challenge season! 🚴‍♂️

    Thank you to everyone who has supported me over the years. Together, we've raised more than $24,000 and ridden thousands of kilometres to help fight kids' cancer. Every donation, share, and word of encouragement has helped make a difference for children and families facing this difficult battle.

    This year is especially meaningful because my son, Jayden, will be cycling alongside me. Together, we'll be riding to support SickKids Foundation and help fund life-saving research and treatments for children with cancer.

    To thank our supporters, we'll be holding a prize draw every month from June through September. For every $25 donated, you'll receive one entry into that month's draw.

    🎁 June Prize: A handcrafted mini porch sign donated by On The Mark Laser Engraving.

    We'll also have additional prize draws on Kick Cancer's Butt Day, so stay tuned for more details throughout the summer.

    This ride is in memory of my daughter Evelyn, in honour of my mother Christine, and for every child and family affected by cancer.

    We invite you to follow our journey, cheer us on, join us for a ride, and, if you're able, support this important cause.

    “I have known Mark for many years and I am proud and blessed to call him my friend/Brother ❤️👊!! I was greatly saddened by the loss of his daughter Evelyn....and I attended her celebration of life and how much she was cherished and loved. Mark is a great father and a family oriented man❤️👊 !! I am glad he is taking his pain, grief and loss and is using it to give him a constructive passion and a way to make a difference; :by raising funds through The Great Cycle Challenge for children's cancer research and treatment, in Evelyns memory. I was encouraged to hear his son Jayden will be joining him this year. It affected their whole family and they are doing something very constructive to help them work through their grief and loss, and keep Evelyns memory alive and honoured within their family ❤️‍🩹✝️. Please consider supporting Mark and Jayden in this very personal Great Cycle Challenge, helping then heal their grief and loss and making a positive difference, helping others”
