There are a lot of ways to run the Chicago marathon and putting a silly wig on and calling it a “fun run” is just one example. Every October Chicago hosts one of the nation’s biggest World Marathon Majors where qualifying runners go on to the Olympics and other world racing events.
Chicago’s marathon is one of the nation’s most popular races because the course is flat and runs right by public transportation stations and hotels, making it easy access for out of town runners. Only the first 45,000 runners can compete though, so participants need to sign up early. If you’re a spectator, you can track specific runners at eight different locations and watch the course from the elevated train tracks for a better view.
