My Story

21 Aug 2025

This September, I am taking part in the Great Cycle Challenge to fight kids' cancer!

This year, I am riding on my exercise bike. I fell in July and broke my right wrist and didn’t realize it was broken for a few weeks, so now it will be in a splint and I can’t safely ride my bike outside. But I am still determined to put in the miles and raise the money for children’s cancer .

I want all kids to be able to experience the joy of being outdoors and having fun. That’s why I bike for children’s cancer research fund. They are striving very hard to find cures for children’s cancer. And that doesn’t just affect children. It affects adults with similar cancers and the knowledge they learn can be transferred to them.

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 and September is Children's Cancer Month.

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.
