Runners are not permitted to move forward into an earlier wave or corral. While we encourage all runners to line up in the corral to which they are assigned, runners are allowed to move back to a higher corral or wave, with the exception of the first corral of any wave. For example, if you are assigned to Wave One, you may move back to Wave Two, Three, or Four into any corral EXCEPT for the first corral in any wave. Violators are subject to penalties and/or disqualification.


We encourage all participants using the B.A.A. shuttles on the Boston common to load the shuttles that correspond with their wave assignments. However, you may load an earlier shuttle if there is room.


After you submit your application, you'll receive an e-mail confirming that we've received your application. Verification of your qualified time can then take up to five weeks as the results from your qualifying race are verified. Once we verify your time, you'll receive a second e-mail that confirms your entrance into the Boston Marathon.

The B.A.A. asks for your cooperation and patience during this verification process. Please do not contact the B.A.A. during this period unless requested to do so by the Registration office.


The average temperature at the start of the Boston Marathon ranges from 45-50 degrees F. The spread of temperature throughout the race can average approximately 25 degrees F, meaning the finish line temperature can average from 70-75 degrees F. However, in years past, there have been examples of extreme weather at the Boston Marathon. See below for examples:


  • 1907 Traces of sleet
  • 1908 Snowflakes and drizzle
  • 1925 Cold wind and occasional snowflakes
  • 1961 Snow squalls driven by winds of 10–12 mph; recorded temperature was 39 degrees
  • 1967 Snow squalls accompanied the runners through the first five miles.

Driving Rain

  • 1970 Mix of rain and sleet; temperatures in the high 30s;
  • 2007 Rain; winds gusting 25-30 mph; temperatures in the mid 40s.

Extreme Heat or Unseasonable Warmth

  • 1905 The temperature was reported to have reached the 100-degree mark.
  • 1909 The temperature soared to 97 degrees.
  • 1915 Reports of “intense heat.”
  • 1927 With the temperature reaching 84 degrees, a newly surfaced, yet uncured, road melted under the runners’ shoes.
  • 1931 Reports of “terrific heat” that “spelled ruin to the hopes of countless ambitious runners.”
  • 1952 The temperature rose to the upper 80s, with a high of 88 degrees.
  • 1958 The temperature climbed to 84 degrees.
  • 1976 For much of the first half of the race, the temperature along the course was reported to be 96 degrees.
  • 1987 The temperature was in the mid/upper 80s and the humidity was more than 95 percent.
  • 2004 The hottest marathon since 1976 (86 degrees at the finish) caused a record number of heat-related illnesses.
  • 2012 The temperature reached 75 degrees by the start of the Women's Elite field (9:30 a.m.), with a high of 89 degrees reported in Framingham (10K mark) by mid-day.
We are able to provide transportation to the start from Boston to Hopkinton for officially registered runners only. There is no public transportation to Hopkinton.

There are a several handicapped-accessible areas in Framingham, Natick, Wellesley, Newton, Brookline, and Boston for spectators to get up close to the race course, but they are not reserved exclusively for handicapped access. There is an area reserved exclusively for handicapped spectators to watch the Boston Marathon at the intersection of Hereford Street and Boylston Street (Boston), on the North side of the course. Spectators can access the reserved area at the intersection of Massachusetts Avenue and Boylston Street (one block West).

No headquarters hotel has been designated for participants, but participants may find it convenient to stay in Boston's Back Bay neighborhood, which is where the race finishes.
No, please do NOT run if you have not been officially entered in the race. Race amenities along the course and at the finish, such as fluids, medical care, and traffic safety, are provided based on the number of expected official entrants. Any addition to this by way of unofficial participants, adversely affects our ability to ensure a safe race for everyone.

Historically, runners who beat their qualifying standard by a larger amount of time are more likely to be accepted into the Boston Marathon. Due to field size limitations, as well as a hightened interest in participation, a "cut-off" time (a time below the minimum qualifying standard for age and gender) has been established. Below is a list of when entrants needed to obtain a faster time than their minimum standard in order to be accepted into the race:

  • For the 2012 Boston Marathon, the cut-off for qualifying times was drawn at those who beat their qualifying standard by 74 seconds or faster. 
  • For the 2014 Boston Marathon, the cut-off for qualifying times was drawn at those who beat their qualifying standard by 98 seconds or faster.
  • For the 2015 Boston Marathon, the cut-off for qualifying times was drawn at those who beat their qualifying standard by 62 seconds or faster.
  • For the 2016 Boston Marathon, the cut-off for qualifying times was drawn at those who beat their qualifying standard by 2 minutes and 28 seconds or faster.
  • For the 2017 Boston Marathon, the cut-off for qualifying times was drawn at those who beat their qualifying standard by 2 minutes and 9 second or faster.

Although these were the cases for previous years, we cannot predict how competitive the registration process will be for any given year, or how quickly it will fill. If you don’t have a qualifying time but still wish to participate, you can apply to run for the Boston Marathon Official Charity Program. Click the button below for more information:


The 13.1-mile, rolling course is an out-and-back route that runs along the Emerald Necklace park system.

  • The B.A.A. Half Marathon will begin and end at White Stadium in Boston’s Franklin Park. The park, one of the oldest in America, is located in Boston’s Jamaica Plain and Dorchester neighborhoods.
  • With a start on Pierpont Road, the course proceeds out of Franklin Park, over the Monsignor William Casey Overpass, and past the Arnold Arboretum and Jamaica Pond as The Arborway becomes The Jamaicaway.
  • The course then passes Willow Pond and Olmsted Park, before the turn-around-point on The Riverway 4.75 miles into the race.
  • On the return, runners hug the western side of the Emerald Necklace, with Leverett Pond, and Jamaica Pond now on the left.
  • The race re-enters Franklin Park and loops around animal enclosures in the Franklin Park Zoo, before finishing on the track in White Stadium.
