Digital clocks, positioned at every mile and 5K mark, indicate the unofficial running time from the 10:00 a.m. start only. Signage indicates mile and 5K marks.


  • Runners unable to finish the race may stop for assistance and direction at one of the 26 American Red Cross first aid stations along the course.
  • Sweep buses pick up runners at every Red Cross station with drop-off at the Finish Area medical tent.
  • Aid stations along the course close at staggered times during the day.
  • Finish area facilities officially close at approximately 6:10 p.m. (which is approximately 6.5 hours about the last participant crosses the starting line) 
  • Runners still out on the course when officials determine that it is time to reopen the roads (approximately a 15-minute per mile pace) will be instructed to move to the right side of the road.
  • Once roads begin to reopen to vehicular traffic, course infrastructure (such as timing systems, course clocks, medical stations, and water stations) will all begin to be closed and cease operation.
  • Runners on the course after this time accept that they will be on their own and should plan accordingly.
  • The B.A.A. will have a team of cyclists in the rear of the pack to assist runners who are at or slower than 15-minute per mile pace.


For your convenience and use during the race, the B.A.A. provides toilets at the following locations on the course:

  • Mile 3 - Ashland
  • Mile 7 - Framingham
  • Mile 10 - Natick
  • Mile 12 - Wellesley
  • Mile 18 - Newton
  • Mile 23.5 – Brookline

These are in addition to the toilets at every water and Red Cross station. Please respect the communities through which the Boston Marathon runs by taking advantage of these facilities, if needed.


There will be a few changes to the finish area for the Boston Marathon. The B.A.A. will offer the opportunity to exit the secure finish area at three locations prior to Arlington Street. More information on these exit areas will be forthcoming. Participants who choose NOT to check gear  at Boston Common will have the option of leaving the secure finish area early to meet with family and friends. (see image below)

The order of our finish area services has been modified. Finishers will receive:

  • Medals
  • Heatsheet® Warmth Retention Cape (see image below)
  • Fluid replacement (Poland Spring Water and Gatorade)
  • Food

If you decide to take advantage of the gear check opportunity  on Boston Common, you will need to walk approximately one half mile to the gear check area to retrieve your bag.

You will receive an email from the B.A.A., requesting from you whether or not you intend to take advantage of the gear check opportunity on Boston Common on the morning of the race.

Heatsheets® Warmth Retention Cape, made from Thermo-Flect® 2, a waterproof, reflective-insulation fabric, reflects radiant heat and minimizes conductive heat loss (wind chill). This innovative material is lined with a soft inner surface, providing  a lightweight, comfortable solution for hypothermia prevention. The cape is hooded for added protection from the elements and has arm holes which allows participants to be hands-free, enabling them to hold food, water and any other essential items while remaining covered and warm.

All information above is subject to change at any time.

1966 - Bobbi Gibb

Although not an official entrant, Roberta “Bobbi” Gibb became the first woman to run the Boston Marathon. Joining the starting field shortly after the gun had been fired, Gibb finished the race in 3:21:40 to place 126th overall. Gibb again claimed the “unofficial” title in 1967 and 1968.
