My Story
13 Aug 2024
This September 2024 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. I'm also riding for myself. In Vietnam in the Army I was exposed to Agent Orange herbicide and now at 74, have Stage IV metastatic prostate cancer.
Your support will change little lives.....and mine too!
Thank you.
John Zac Brennan

“Thanks Fitz for your help. I’m hoping to recruit more riders to join the Great Cycle Challenge this year. Our daughter is getting married this September and my miles will be harder to accrue. My cancer is currently stabilized so I’ve been riding regularly. But by the end of the day I suffer from TOAS (Tired Old Ass Syndrome). Thanks again for your help.”
