The Bank of America Chicago Marathon participant guide includes all the information participants need to have a great race weekend experience. The guide will serve as a step-by-step manual to assist participants during race week, from the Abbott Health & Fitness Expo to race morning in Grant Park and during the race itself. Inside, you will find schedules, policies and detailed information on the weekend’s events.

As part of the Chicago Marathon’s commitment to sustainability, the guide will be available in a digital-only format this year.
