My Story

8 Feb 2026

This September 2026, for the 12th year, I'm again taking part in the Great Cycle Challenge to fight kids' cancer!

Why? Because right now, cancer is the biggest killer of children from disease in the United States. Over 15,700 children are diagnosed every year, and sadly, 38 children die of cancer every week.

Kids should be living life, not fighting for it.

So, I am raising funds through my challenge to help these kids and support Children's Cancer Research Fund to allow them to continue their work to develop lifesaving treatments and find a cure for childhood cancer.

Please support me by making a donation to give these kids the brighter futures they deserve.

Your support will change little lives.

Thank you.

“Kyle, Thank you for the support! 12 years of riding for these children have brought me a peace in my life over the years. It's Brothers like you that are also helping the GCC & children who receive the benefits of your donation. Yes, the songs of John Denver are coursing through me as I ascend my faithful bike to rake up some rides this season. nothing like the rare air and blazing sun to help you keep the pace to get back to some air-conditioning. Susan and I officially moved back to Colorado and on July 3rd crossed over the Stateline in time to celebrate our 23rd wedding anniversary by taking a ride into the mountains on July 4th. I hope all is well with you and the family my friend. Peace & Love, Erv”
