Runners can start applying to register for the 2018 Bank of America Chicago Marathon as early as next week.

The guaranteed entry application will open at 10 a.m. CST Tuesday, Oct. 24. Participants can qualify for guaranteed entry based on a previous marathon time, legacy finisher status or entry with an international or charity group. 

For time qualifiers, the marathon will implement a new system this year based on age and gender to determine who is eligible for guaranteed entry. 

Non-guaranteed registration will open Oct. 31. Runners who do not qualify for automatic entry but wish to run the 2018 marathon can submit an application, which will be entered into a lottery. Results will be emailed to all applicants on Dec. 12.

All applications are due by Nov. 30. The 2018 Bank of America Chicago Marathon will be held on Sunday, Oct. 7, 2018.
