This was such a great race for my first marathon! So well organized and the swag is really awesome looking! Aid stations were very strategically placed and elevation changes were minimal until this very end (nice little challenge to finish it off). Also, it's a great way to have a mini tour of Chicago if you've never been, and there were 1.7 MILLION spectators, which is so clutch at mile 24 when you might be struggling a bit. So glad I did this and it has definitely motivated me to do more in the future!
