Boston Marathon Results and Finish Times Analysis: How Long Does it Take?

By Raymond Britt and RunTriMedia

More than 26,600 runners finished the 2019 Boston Marathon in solid overall average time of 3 hours, 53 minutes. By comparison, the average finish time at Boston 2000 to 2019 is just a minute slower, 3:54. Notably, the 2019 average was 4 minutes faster than the average time of 3:57 in terrible weather conditions in 2018.

At the next level of detail, here are the average finish times by gender and division.


We are currently crunching the numbers to provide comprehensive details comparing age group times over multiple years, and will present the results analysis here shortly. Scroll down to see similar analysis from previous years.

2018 Recap

Rough year at the 2018 Boston Marathon as runners had to endure what some are calling the worst weather conditions in three decades: cold, rain, wind, and wind chill. 

The elites seemed especially punished by the weather, but believe it or not, the average finish time for all in 2018, 3:57, was one minute faster than the 3:58 in 2017.



Here we present our annual comprehensive results analysis for all starters, finishers, age groups and the impact of weather on finish times, plus a link to BAA.org's searchable results. 




















Our analysis of Boston Marathon from the years 1999 to 2018 indicates the average finish time is 3:54; three hours and fifty-four minutes. That's at least 25 to 30 minutes than the average time of the top 25 marathons.

But there's so much more specificity we can provide about average finish times. We've crunched the numbers to illustrate:
  • Boston Marathon finish times 2000 to 2017, 
  • details on 2017 by age group and by age group within each of four waves
  • Compare Boston 2012 against both Boston 2004 and Boston 2010 by race division, by gender and age, by city, by Boston Qualifiers, and more.

      We've run Boston 13 consecutive times and, we can assure you: there is nothing like it in the world. You'll know what I mean when you get there. The thrill of starting the race in Hopkinton can feel amazing, but often, the next 26.2 miles can be unpredictable. We've been analyzing Boston races for years, and here we present the highlights of analytics in charts and links to other articles that may help you run your best.
