100 Ultras by age 100

I have been a runner for most of my life.  Going on now almost 40 years.  I couldn't bear to live without running.  Running has given me so much in my like so far, I can't begin to describe in a short paragraphs alone.  I am now 54 years old, and have been struggling for a while with the fact that I haven't done anything positive to help the world in any way with all this running I do.  

I lost my Mother in 2003 to Alzheimer's.  In case you don't know, this is a disease that affects 5 million Americans, has no cure and is a progressive disease which leads to death.  Since if affects the brain, a person eventually in the later stages has to completely depend upon a caregiver to help with all simple tasks of daily living.  It is said it will affect 1 in 85 people worldwide by 2050.
