The Chicago Marathon is one of the top marathons in the country. I am not a runner (LOL), but I do like watching and cheering them on. This year we know someone who is running, so that should be fun. All the info you need including how to keep track of your friends, the route, and good spots to watch can be found on the official website at www.chicagomarathon.com
Here’s the route. Click it for a larger map.
