Video: Why I'm Running the Boston Marathon

South End resident Kara Walsh will be one of thousands running in the 2011 Boston Marathon on Monday as part of the The Dana-Farber Marathon Challenge Team. Before signing up for the race, Walsh had never run more than five miles in her life. She said she's running in honor of her father, who passed away from Lou Gehrig's Disease, as well as the patients she worked with while interning with the Jimmy Fund Clinic.
