2013 Chicago Marathon By The Numbers

There’s a lot of information to gather (and analyze) from 39,000 runners. 

The Chicago Marathon is one of the largest annual marathons in the world, with just over 39,000 runners finishing this year’s race. As you might imagine, there’s a lot of information about the participants that becomes available afterward, including average finish times, average split times for the first half of the race versus the second, how those values compare year over year, the number of finishers by age group and how many runners ran negative splits.

Raymond Britt of RunTriMedia.com has taken all of this data from Sunday’s race and compiled it into 11 informative charts and graphs, found below.
