Registration for the 2013 Bank of America Chicago Marathon officially opened on February 19, 2013. Due to an overwhelming response of interested runners, the Chicago Marathon website experienced some technical difficulties within hours of registration opening.

As a result, the remaining 15,000 available entries for the Chicago Marathon race this October 13th will be assigned via a random lottery March 5-7, 2013. The selected names will be announced on March 12th and the winners will have until March 14, 2013 to claim their entry and pay the registration fee.

If you were not able to register for the 2013 Bank of America Chicago Marathon on February 19th or if you did not receive an entry via the lottery, you may be eligible for one of Team NPCO's limited Post-Close entries.

Please fill out the form below to be considered for a Team NPCO Chicago Marathon Post-Close Entry. By filling out the form below, you are not guaranteed an entry. However, you may be contacted by an NPCO staff member who will explain what the next steps will be.
