This years Chicago Marathon presented by Bank of America will be held on Sunday, October 10. It happens to fall on 10/10/10 this year.

The Chicago Marathon is one of the five World Marathon Majors. The others are the Berlin Marathon, Boston Marathon, London Marathon and New York Marathon. This year marks the 33rd anniversary of the event, as it has taken place every year since 1977.

You can usually expect to see records come close to being broken at this Marathon, as the course in Chicago is known to be very flat and fast. This years race will be limited to the first 45,000 runners who sign up, and everyone will get an official time, if they finish the race within 6 1/2 hours.

Bank of America is sponsoring the event for the 3rd consecutive year, after they acquired LaSalle Bank in 2007. Every year you can expect to see between 27,000 and 35,000 people to finish the Chicago Marathon.

The beginning of the marathon will be broadcast on NBC 5 Chicago from 7AM to 11AM on Sunday, and the entire marathon will be broadcast streaming online at NBCChicago.com.

If you are running in this years marathon, you can expect to get a nice tour of Chicago. The race path will go by many historic landmarks including the Chicago Theatre, City Hall Building, Former Engine Company 27, Sydney Kent House, Charles J. Hull House, and more.
