RULES & SAFETY

CHICAGO IS YOUR START LINE IN

YOUR SAFETY IS OUR TOP PRIORITY

The Bank of America Chicago Marathon requires all participants to abide by the event rules in order to create an ideal and fair event. Additionally, please be aware of your surroundings and help foster a culture of safety at the race.

EVENT RULES

The event rules are intended to help produce and direct a large scale event, to ensure the safety of all participants, to meet the requirements of local government permits and to be compliant with applicable USA Track & Field (USATF) and World Athletics regulations for participant performance records and event liability.

Event alert system

A color-coded Event Alert System (EAS) will communicate the status of course conditions to participants leading up to and on race day. The levels range from Low (green) to Moderate (yellow) to High (red) to Extreme (black) based primarily on the weather, as well as other conditions.

  • Email and website communication during race week will inform participants of the current Event Alert System status and provide preparation tips based on advance weather forecasts.
  • Updates will be made at the Abbott Health & Fitness Expo via handouts at the Participant Packet Pick-up area and public address announcements.
  • On race day, the current Event Alert System status will be communicated via public address announcements and color-coded signs/flags at the start and finish areas, and along the course at each of the 20 aid station locations and via large digital traffic message boards.

All participants should familiarize themselves with the Event Alert System prior to the race, remain alert for directions from race officials and announcers and take precautions to prepare properly for varying weather conditions on race day.
