If you feel like you need medical assistance on race day, you are encouraged to seek help from a medical volunteer or visit a medical tent in Grant Park or on course.


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.
