My Story

9 Jul 2026

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

  • My financial goal nearly met!
    30 Aug 2026

    Friends and family,

    I am 2-days out from beginning my trek on bicycle and have nearly met the $500 goal I set. You are incredible! I encourage you to push me every year. Although 125 miles this year may seem modest (I do ride a pedal bike with no electric modification:), it can be extended...reasonably:) I will pledge to increase my miles by a mile for every $10 above the $500 mark by September 15th to limit of 200 miles.
