If one person decides to get checked for cancer and a life is saved because we met and they heard my story, then it's worth something.

I met 92-year-old Isabelle Thomas in Cedar Rapids, Iowa. She has fought four different types of cancer and just refuses to give up. She is just one of the dozens of reasons why I'm walking.

I left Virginia and for the first hour or so, I kept thinking, 'What are you doing?' but as I continued on, I realized just how many Americans are impacted by cancer and my resolve kept growing,

The French have a saying, 'Certainly you need money to live, but not to love,' and I agree. Money means nothing to me, but my friends whom I've met through cancer mean everything.
