Just in time for Monday's Boston Marathon, here is a sneak peek at the first-ever feature-length documentary made about the historic race. Boston will take a look at the marathon's triumphs and sorrows, attempting to convey what makes the race so special. "There's no one that can watch the Boston Marathon and not be inspired somehow by someone," said Olympian Shalane Flanagan, and we couldn't agree more. Whether it's runners lifting one another up, bombing survivors proving they are stronger today than ever before, or heartwarming tales of love along the course, there is something magical about Marathon Monday. It's the reason runners persist in their pursuit to gain entry into the coveted race, and it's why two million spectators show up every year to cheer them on.
