My Story

This September, I am 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.

Karl

“Thank you so much for showing your support in this endeavor! Halfway home in my mileage, almost:) We've returned from camping with our granddaughter (costing me 2 days of riding). I often think about the parents of these children with cancer and couldn't help looking at Sophia in a little different light. I ride with a bit of a "thank God" for her health today.”

“Tim, it means a great deal to me that you support this mission. I was reluctant to get out and ride in this wind today, however, you motivated me by your contribution to "get out and ride" (as Rita puts it:) Interesting fact: It was the year that you and I retired that I began riding for children's cancer. Be well.”
