The B.A.A. recommends that 5K runners park at the 100 Clarendon Street Garage in Boston’s Back Bay. With race-day road closures in effect, this is the best location to park your vehicle on Saturday morning. We strongly advise those entrants who are driving to park in the 100 Clarendon Street Garage, or other area parking garages listed here:

  • 100 Clarendon Street Garage, Boston, MA 02116
  • Millenium Place Garage at Ritz Carlton, 6 Avery Street, Boston, MA 02111
  • Standard Parking, 290 Tremont Street, Boston MA 02116

Please note that Charles Street will close at 5:00 a.m. and drop-off access near the start line will be blocked. If you plan on being dropped off on race morning, please plan to do so on Beacon, Boylston, Tremont, or other nearby streets.

The start and finish line for the B.A.A. 5K is located at Charles Street between the Boston Public Garden and Boston Common. In order to ease course congestion, a multiple pulsed start program will be implemented. Runners will be seeded according to their expected finishing time. Signs will be positioned in the start area on Charles Street to indicate your start position. The timing and scoring system will begin recording your time once you cross the starting line. Your net time will be your official time.
