20 aid stations (see locations below) 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)
  • Water
  • Public address announcer

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

Lemon-Lime Gatorade Endurance Formula will be available on course at all aid stations. Endurance Formula has nearly two times the sodium and three times the potassium of traditional Gatorade. Newly reformulated, It now contains no artificial flavors or sweeteners and has a new, lighter flavor.

Gatorade Endurance Carb Energy Chews will be available at Aid Station 9 (Mile 12.5) and Gatorade Endurance Energy Gels will be at Aid Station 13 (Mile 17.8). Aid Stations 15-18 (Miles 20-23.5) will offer bananas.

Each aid station is approximately two city blocks in length; participants are advised to continue moving through the aid station if the first tables are too crowded to conveniently obtain fluids.

Medical support

Medical staff is available at 21 on-course locations (20 aid stations and an additional medical tent in the final mile). Medical tents can be identified by tall, red, blade signs with a medical icon. Each tent is equipped with a team of certified medical personnel, ambulances, emergency and first aid supplies.

In Grant Park, the Main Medical Tent is located just beyond the finish line. An additional medical tent is located in Grant Park adjacent to the Bank of America Chicago Marathon 27th Mile Post-Race Party. For the safety of all participants, only those requiring medical assistance will be allowed access to the medical tents.
