I noticed that Chicago made slight changes to the 2018 marathon course from previous years.
Is there any reason for this ?
The course goes 2 blocks farther north and there were many other minor changes.
Is this new course an improvement ?
I noticed that too. The turn west is now on Monroe when it used to be on Adams. The half mark used to be just over Halsted in Greek Town, not it's all the way back on Washington. All the minor changes added up to a decent sized change in the course
