Runners with an active, consecutive streak of Boston Marathon finishes of any length who started the 2013 Boston Marathon and reached the half marathon checkpoint or later but did not have the opportunity to cross the finish line on Boylston Street may count the 2013 Boston Marathon as an official finish and a preservation of their streak. In addition, those runners with 10 or more consecutive Boston Marathon finishes will be eligible to register for the 2014 Boston Marathon during a special registration period from August 19 to August 29.
