That's a great cause you are taking on, and I admire that.
21.5 is about 20 miles too far for my old back, so I must pass....
I donate $$ yearly to the Susan B Komen Breast Cancer Walk in San Diego. Two of my friends had a double removal, and are now cancer free. One was 45 when she had it done five years ago, and the other 27 in 2008. Brave gals and they had lots of help from friends etc.
