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*
  • Standard and ADA portable toilets
  • Gatorade Endurance Formula (lemon-lime flavor)
  • Public address announcer
  • Water

*Runner Transport vehicles provide non-emergency transportation back to Grant Park if a participant is unable to complete the race.

Gatorade Endurance Carb Energy Gel stations are located at Aid Station 10 (Mile 13.6) and Aid Station 14 (Mile 18.2). The caffeinated flavor offered will be strawberry. One serving of Gatorade Endurance Caffeinated Energy Gel has 30 mg of caffeine. The non-caffeinated gel flavors offered will be mango and vanilla. One serving of Gatorade Endurance Non-Caffeinated Energy Gel provides 20 grams of carbohydrate, 100mg of sodium and 80 calories.

Aid Stations 15-18 (Miles 19.5-23.5) will offer Chiquita Bananas.

Don’t miss the Biofreeze Pain Relief Zone around Mile 21.2 (Cermak Road and Archer Avenue) where the Biofreeze Cooling Crew will be armed with Biofreeze spray to help Cool the Pain to get participants across the finish line.


Medical support is available at 22 on-course locations: medical tents are located at all 20 aid stations with additional medical tents located between Mile 14 and Mile 15 and in the final mile. Medical tents are indicated by tall, red, blade signs with the medical icon. Each medical tent is staffed by a team of medical professionals equipped with medical supplies and equipment, 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 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. If you feel like you need medical assistance on race day, you are encouraged to seek help from a medical volunteer or to visit a medical tent in Grant Park or on course.

Lend a hand, save a life! Participants, volunteers and event staff are encouraged to watch an instructional Hands Only CPR video. This training is critical and can be lifesaving.


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. Participants outside of the time limit may not be recorded or published as official finishers and may not receive full on-course support from aid stations and traffic safety personnel.


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.


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. Motorized devices of any kind are prohibited.

The use of selfie-sticks, camera mounts, video devices, computers or any similar devices by anyone while participating in the event is prohibited.

Camelbaks® and any type of hydration backpack are not permitted. For the avoidance of doubt, fuel belts and hand-held water bottles are allowed. Please be aware you may be asked to empty the contents of these containers before entering Grant Park.
