If your Number Pick Up Card does not reach you before race weekend, please be sure to bring a photo ID with you to Number Pick-Up at the John Hancock Sports and Fitness Expo located at the Hynes Convention Center. Go to the "Replacement Number Pick-Up Cards" booth near number pick-up, show your valid photo id, and a volunteer will print a new card for you. You will use that new card to pick up your number. We are requiring that all participants claim their own bib number at the John Hancock Sports & Fitness Expo during normal expo hours. Friends or family will not be allowed to claim your bib number for you.

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 "cutoff" 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 cutoff for qualifying times was drawn at those who beat their qualifying standard by 74 seconds or faster. 
  • For the 2014 Boston Marathon, the cutoff for qualifying times was drawn at those who beat their qualifying standard by 98 seconds or faster.
  • For the 2015 Boston Marathon, the cutoff for qualifying times was drawn at those who beat their qualifying standard by 62 seconds or faster.
  • For the 2016 Boston Marathon, the cutoff for qualifying times was drawn at those who beat their qualifying standard by 2:28 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 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

1920 - Ashland Start

The Boston Marathon began in Ashland, Massachusetts from 1897 through 1923 then moved to Hopkinton for the 1924 race. The course was lengthened to 26 miles, 385 yards to conform to the Olympic standard, and the starting line was moved west from Ashland to Hopkinton. Since then, the race has started in Hopkinton every year.
