April 18 there's another run blessed by the Irish. It's on the other side of The Pond. The 115th running of the Boston marathon attracts a million spectators a year. The course is fabled -- for its beauty and its brutality. Rural Hopkinton is the jumping off point. Then the run winds through countryside and townships before terminating in Boston's Kenmore Square, in the shadows of Fenway Park. But first contestants must conquer Heartbreak Hill -- and their own demons.
