The Bank of America Chicago 13.1 half-marathon sent runners through Chicago’s West Side parks on Sunday, with the 13-mile race starting at 7 a.m. and finishing in Garfield Park. The course cut through Douglass and Humboldt parks, drawing a moving line of traffic controls across several neighborhoods before the morning was over.

The race is what many Chicagoans were searching for on Sunday because it brought immediate changes to streets and parking along the route. No-parking zones took effect at 1 a.m., and street closures followed between 5:30 and 11 a.m., affecting drivers and residents near the course as the field moved through the parks.

Chicago’s Office of Emergency Management and Communications said streets would reopen as runners passed points along the route, a step-by-step approach meant to ease the shutdown as the pack advanced. That did not mean the disruption ended with the finish line. The closures were set to remain in effect until 5 p.m. Monday, long after the last runner reached Garfield Park.

That schedule left the city with a split reality: a Sunday race built around parkland and a Monday cleanup that reached into the workweek. The event itself was brief, but for people living or driving along the route, the restrictions lasted far longer than the competition.
