Start Corrals

The start line for the Byline Bank Chicago Spring 10K 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.

All 10K participants will start at Corral J. Please keep in mind that this is a self- seeded corral; in other words: first come, first serve. 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.

*Corral changes: There are no corral changes available for the 10K as all participants will start in the same corral. 

Elite/Wheelchair: Corral A
13.1: Corrals B – I
10K (Self seeded): Corral J
