I'm Riding For

Hallie Lynn

Hallie Lynn

You can read the full story on this link below. https://greatcyclechallenge.ca/about/the-kids/meet-hallie-lynn “ However, that same day, Terrah received an unexpected call from an oncologist at SickKids, requesting that they bring Hallie-Lynn back to the hospital for further testing. Filled with uncertainty, the family returned to SickKids and Hallie underwent a number of tests. A fellow shared the devastating news that they suspected Hallie-Lynn may have neuroblastoma, but they had to confirm the diagnosis with more tests. This brave girl was admitted for four days to continue with testing, including an MRI. About a week after Hallie-Lynn was discharged, Terrah and Joel received the call confirming that their baby daughter had stage 4 high-risk neuroblastoma. Since then, this brave little girl has endured high-dose chemotherapy, bone marrow transplants, radiation therapy and surgery to remove her tumour. ” I will ride for Hallie Lynn this year. God bless her and the family.

My Story

1 Aug 2025

My father was taken way too early to cancer. Other relatives and friends have lost the fight to cancer.

CANCER SUCKS!

KIDS’ CANCER REALLY SUCKS!

I had an idea this year to help me continue to help these brave kids.

Last year it was difficult to complete the challenge. With our basement, flooding misfortune behind us, I am ready to throw my support behind the families and especially the kids were currently fighting cancer and need financial support. It’s almost become natural to lose a parent to cancer, but to me, it’s almost unthinkable to have to lose a child to cancer. Will you please support this cause and support my efforts to make this a success. Peace.

Thanks

Jack

  • Final day of 3 day ride
    7 Aug 2025

    During our Epic GCC ride of 300km over 3 days, Marcus and I are ready to start day 3 soon. We are in Collingwood at a holiday inn enjoying the comfort.

    Both of us are feeling it in our calves today. We will power through it.

    My knee “bullet hole” wound is heeling up with the Tegaderm patch.

    Gotta ride 100+ today to Bayfort Camp.

    LETS GO!
