World’s Largest & Most Recent Marathon Study

In the largest marathon study of recreational runners ever conducted, we researched marathon data information from all over the world and compiled a total of 3.5 million marathon data records, which is the most that have ever been collected. The information researched included 196 marathons from the years 2014-2017, and 238 nationalities that span out over 39 countries and 7 continents in total. Below you will find the most interesting and compelling statistics discovered throughout this study.

Age Distribution

• The fastest age group is 40-49 with an average time of 4:22:03
• The fastest age group for men is 40-49 with an average finish time of 4:11:19
• The fastest age group for women is 20-29 with an average finishing time of 4:42:10

In this study, we also looked at the marathon statistics pertaining to the different age groups and how those age groups were performing in running over the years of 2014-2017. Age group 40-49 is the fastest category with an averaging finish time of 4:22:03, the age group 0-19 is neck and neck, only lagging by a mere 14 seconds and in third is the age group 30-39 with an average finish time of 4:23:59. Age Group 80-89 closes the table with an average finishing time of 6:09:48. When it comes to age groups pertaining to each gender, the fastest age group for men is 40-49 with an average finish time of 4:11:19 and the fastest age group for women is 20-29  with an average finish time of 4:42:10. When we looked at each individual year, the age group 40-49 took the gold for every year, with the exception of 2017 where the age group 0-19 took the win. 

Senior Citizens Take the Lead

The age group 40-49 ranks the most popular age group in 29 countries, the age group 30-39 is the most popular in 20 countries, and the youngest age group 0-19 is the most popular in 5 countries. The age group 40-49 is the most popular in all continents with the exception of North America, where the age group 30-39 is the most popular. The two biggest age groups of marathon runners is 40-49 which is 30.84% and 30-39 which is 31.08%. These two age groups make up for more than 60% of marathon participation.
