I'm Riding For
Two people: the daughter of close friends. And in memory of my nephew, Matt.
The daughter of my friends is undergoing treatment and her prognosis is very good. I’m withholding her name at her request. My nephew, Matt, was diagnosed with a brain tumor at a very young age. He was a wonderful person and gave us all a lot during his 29 years.
My Story
I can’t believe this is the 10th year that I am taking part in the Great Cycle Challenge to fight kids' cancer!
Once again I am raising funds through my challenge to support the Children's Cancer Research Fund to allow them to continue their work to develop lifesaving treatments and find a cure for childhood cancer. To those of you who have donated before, my heartfelt thanks, and I hope you can do so again. For those of you who haven't donated, please know that ANY amount is appreciated.
Please support me by making a donation to give these kids the brighter futures they deserve.
Your support will change lives.
Thank you so much,
Bob
