I'm Riding For
In memory of my nephew, Matt.
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
This is the 11th 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
