Chicago is one of, if not the best marathon. The crowd is packed along the route, cheering on all of the runners the entire time. The course is almost entirely flat. The volunteers and workers are incredibly supportive and helpful and everything runs like clockwork. This was my 4th time running

I would just like to say thank you to all of the organizers of the marathon and all of the volunteers. You were all great! The encouragement from the spectators who were even given designated cheer-stations - which I again credit to the events great organizers who made that happen. Those

Really well run race, and quite flat, some hills at miles 8-10 but that's about it. The pacers I had were excellent I highly recommend this race
