Register Blue


  • Drawing registration will be open between 7 AM on October 1 and 11:59 PM on October 8.  The entry fee is $2.50.
  • You need to be registered for the 2016 Boston Marathon, planning to enter as a Boston charity runner, or have a BAA invitational registration to be eligible to participate in Boston 2 Big Sur.
  • You can only register ONCE for the drawing; if you register multiple times, the duplicate entries will be removed.
  • The date you enter the drawing will not effect your chances of being selected.
  • Drawing results will be announced on Monday, October 12.  Both those selected and not selected will be sent an email regarding their status.  Because emails don't always land in someone's inbox, we will also post a list of those selected HERE.
  • Registration invites will be sent to all selected on Tuesday, October 13.  You are under no obligation to register if you change your mind, but please email sally@bsim.org if that is the case.  Those selected will have 10 days to register for Boston 2 Big Sur. Beginning October 23 your registration opportunity will be voided.
  • There will be a wait list following the close of registration.  This will be based on the random selection order beginning with the first person not selected.  If a slot opens, we will notify the next person in line.
  • If you are already registered in the open Marathon (via the July drawings) and are selected during the B2B drawing, go ahead and register for B2B.  Email sally@bsim.org if this is your situation and we will void and refund your open marathon entry.
  • If you are registered in the open Marathon (via the July drawings) and are NOT selected in the B2B drawing, you may still run the Big Sur Marathon but are not eligible for the B2B perks.
