This was my first time running the Chicago Full Marathon and it was an incredible experience. Since the race was scheduled to be in early October, I knew there was a chance it would be very cold, considering the unreliable Chicago weather patterns. With that said, it ended up being 65 degrees and sunny. The course was great- it took the runners through a great tour of Chicago- starting downtown near Grant Park, up through River North, Old Town, Lincoln Park, up through the heart of Boystown and back towards Michigan Ave. for the FINISH. There were aid stations everywhere, along with restrooms. This is definitely a race to run if you are shooting for a PR as the elevation is primarily flat. Best race in Chicago, in my opinion!
