In September of 2011 my grandmother lost a multi-year battle against breast cancer. I myself survived Leukemia in 2002. I'm running the Twin Cities Tough Mudder on May 20th, 2012 in her memory and to help raise money for Cancer research so that others may have a chance at surviving. All money raised will be donated to the American Cancer Society.
