Fathom Events, in partnership with Runners World, bring the first ever feature-length documentary about the worlds most legendary running race, the Boston Marathon, to select cinemas nationwide on Wednesday, April 19 only. BOSTON: An American Running Story tells the story of the oldest annually contested marathon in the world from its humble origins starting with only 15 runners to the present day. Following the tragic events of 2013, BOSTON records the preparations and eventual running of the 118th Boston Marathon one year later, when runners and community gather in support of one another for what will be the most meaningful race of all. BOSTON is more than a running documentary, it is a timeless story about triumph over adversity for runner and non-runner alike.
