Aid stations

20 aid stations are located along the course approximately one to two miles apart. Each aid station consists of the following amenities in this order:

  • Medical Tent with access to a Runner Transport vehicle*
  • Toilet facilities
  • Gatorade Endurance Formula (lemon-lime flavor)
  • Public address announcer
  • Water

Medical support

Medical support is available at 21 on-course locations: all 20 aid stations and an additional medical tent in the final mile. The tents are indicated by tall, red, blade signs with the medical icon. Each medical tent is staffed by a team of medical professionals, is equipped with emergency and first aid supplies and has access to ambulance service.

In Grant Park, the Main Medical Tent, Podiatry Tent and Ice Station are located directly beyond the finish line. An additional medical tent is located in Grant Park adjacent to the 27th Mile Post-Race Party. For the safety of all participants, only those requiring medical assistance may access the medical facilities.


Course time limit

The Bank of America Chicago Marathon has a course time limit of 6 hours and 30 minutes. After this time, the course will re-open to vehicular traffic. You must maintain a 15-minute per mile pace (approximately) or faster, completing the full marathon distance—start line to finish line—within the event time requirement. Those who finish outside of the time limit will not be recorded as official finishers and may not receive full on-course support from aid stations and traffic safety personnel.


Clocks and mile markers

Timing checkpoints are positioned at the start line, at each 5K, at the halfway point (13.1 miles) and at the finish line. Your MYLAPS BibTag timing device will register split times at each of these checkpoints.

Digital clocks are positioned at the start line, throughout the course and at the finish line to provide the elapsed race time. Mile and kilometer markers are positioned at each mile and 5K to assist you in locating the clocks. Digital clocks at the finish line will display the elapsed race time, which begins with the official race start time. Your individual race time may differ depending on when you cross the official start line.


Prohibited devices on course

Wheeled devices are not permitted on the Bank of America Chicago Marathon course by anyone other than a registered and authorized wheelchair, handcycle and duo team participants. Prohibited wheeled devices include non-registered wheelchairs and handcycles, baby joggers, strollers, skateboards, rollerblades and bicycles.
