Very poor design here...Is there a place to sign up for this race !!! I ran in this race hosted by races 2 run for last 5 years.... Now I since they apparently dropped it can't seem to find a place to register

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

This is my 2nd time running this marathon. In 2015, I ran it for the first time and was my first marathon, so it holds a special place in my heart. Will continue to do it.
