The star of the show

Race day kicks off with a one-loop half marathon course through Chicago’s historic and scenic museum campus alongside Soldier Field with a finish at Maggie Daley Park.

Course Map

The Byline Bank Chicago Spring Half Marathon & 10K will start and finish along Columbus Drive, adjacent to our new race venue, Maggie Daley Park. The course will utilize a combination of closed street* and Lakefront Path giving way to sweeping views of Chicago’s famed skyline and Lake Michigan.

*Course pending final approval by the City of Chicago and Chicago Department of Transportation.

Start Corrals

The start line for the Byline Bank Chicago Spring Half Marathon is located along Columbus Drive. The start line is approximately one-third of a mile from the Gear Check area within Maggie Daley Park. Please allow extra time to check gear and walk to the start line.

To lessen course congestion and to provide each participant with a quality experience, the Chicago Spring Half Marathon will utilize a corral wave start. Participants must assemble in their assigned corral (corral letter located on the race bib). Half Marathon corrals will begin to close, following the below schedule, promptly at 6:45 a.m.

Half Marathon Wave 1 (Corrals A – F) line up in your corresponding corral along Columbus Drive, north of Monroe Street. Wave 1 Corrals will close at 6:45 a.m. Those who are in wave 1 and not in their assigned corral by 6:45 a.m. will be directed to wave 2 corrals and must start with wave 2.

Half Marathon Wave 2 (Corrals G – I) line up in your corresponding corral along Monroe Street, east of Columbus Drive. Wave 2 Corrals will close at 7:05 a.m. Half Marathon runners not in their corrals when half marathon corrals close will not be allowed to start the half marathon and will be moved to the 10K race.

10K (Corrals J – L) will line up along Columbus Drive after the Half Marathon has cleared the start line and race staff open 10K corrals at 7:25 a.m. 10K corrals will close promptly at 7:40 a.m. 10K runners not in their corral when corrals close will not be allowed to start the race.

The timing chip (located on the back of the bib) will record the official race time. The participant’s time does not start until they cross the start line and stops when they cross the finish line. Corral A will start at 7:00 a.m. with subsequent corrals being released in waves. Participants will follow the corral volunteers to the start line as the corrals are released.

Please Note: Participants may move back a corral, however you may not move ahead a corral*. Participants displaying unsportsmanlike conduct will be disqualified and possibly banned from future Life Time events.

*Need to change your corral? Corral changes are to be made in person during packet pick- up hours at the Solutions desk, pending space availability only. Please make sure to have proof of a time faster than the one submitted during your registration.
