  Have you been dreaming of running the Boston Marathon? Need to shave a few minutes off your qualifying time? Or maybe you're just looking for the perfect course to set a new PR? Whether Boston is your goal or not, the Bound for Boston Marathon & Half Marathon is for you.

  We're racing around Northfield High School, and the course is a 1-mile super flat & super fast loop! The Full Marathon is USATF Certified making it a Boston Qualifier!

  This event is uniquely designed for serious runners. We will have water and an electrolyte drink at the aid table. Participants are welcome to bring their own personalized aid to place on the aid tables, allowing you to grab exactly what you need each time you pass. Many runners even bring a cheer crew to help hand out fuel and keep the motivation high throughout the race.

  To maintain the best possible experience, this is intentionally a small, focused event, capped at just 75 participants.

  We will have a great race shirt and finisher medals for all participants. Awards for both distances are in the usual 5-year age groups.

  Fast course, flexible support, and a chance to chase your goals—this is the race that lets you run your perfect day.

  By design this will be a smaller event, focused on getting you your fastest time.
