My Story

21 Sep 2025

UPDATE:

Entering the home stretch and getting close to the $5k and 500 miles goal- but not quite there yet.

September has rolled around, and I will be taking part in my third (and most likely last) Great Cycling Challenge to raise money to fight kids' cancer.

I will be turning 70 this month and always seeking justification to maintain my cycling habit. The GCC does exactly that.

I've set the bar a bit higher this year- hoping to raise $5000 and hope to coast through 500 miles again.

Everyone has been incredibly generous and supportive the last two years, and I'm hopeful you all will again put a smile on this old guy's face and help out the kids.

Kids should be living life, not fighting for it.

Please join me in the fight against kids' cancer by donating at my personal fundraising page.

All funds raised will support Children's Cancer Research Fund to continue their work in developing innovative treatments and finding a cure for childhood cancer.

Thanks a bunch

BOB
