How the Chicago Marathon Came to Be

In 1977, Michael Bilandic, then the mayor of Chicago and an enthusiastic runner, threw his support behind putting on a race along the downtown streets of the Windy City. The Chicago Marathon was dreamed up by five founders, including original race director Wendy Miller, in November of 1976, and officially kicked off on September 25, 1977.

Fees for that debut event were just $5, and more than 4,200 runners showed up to compete—including 8-year-old Wesley Paul, who finished in 3:15:20—making the Mayor Daley Marathon (named after former Chicago Mayor Richard Daley) the largest 26.2-mile race in the world at the time. The 1977 men’s winner was Indiana native Dan Cloeter, who ran 2:17:52, while Texan Dorothy Doolittle won the women’s race in 2:50:47.

The enormous success of that debut marathon not only established the annual race for years to come, but it also set other running initiatives into motion. Under Bilandic’s hand, what was once an old equestrian trail along Lake Michigan was paved into a five-mile running path, which eventually became the 18-mile lakefront route Chicago Marathon course map.

Race Size and Weather

While Chicago’s flat course certainly contributed to fast performances in the past, the infectious atmosphere, competitive field, and weather on race day has helped, too. In 2007, the race began capping its field at 45,000 participants, making it more than 10 times larger than it was 30 years prior. In 2019, the last Chicago Marathon before the COVID-19 pandemic, 45,956 runners Results from the 2024 Chicago Marathon.

The average highs/lows in early October for Chicago are usually in the low 60s to low 40s. But in 2007, marathoners suffered record-high temps of 89 degrees and 73 percent humidity on race day. In 1988—the coldest race ever recorded—they endured temps as low as 21 degrees. In 1993, participants ran through snow. In 2019, runners had perfect marathon weather, with lows in the high 30s and highs in the low 50s. On Sunday, October 9, the expected low is 49 and high is 61—dang near close to perfect.

Quick Rundown of the Course

Because much of the route is flat as a pancake, and race day mornings are usually brisk, it can be hard to hold back in the early miles of Chicago—but no matter how good you feel from the gun, 26.2 miles is still a long way to go, so proper pacing is key for staying strong through the finish.

The looped course starts and finishes in Grant Park along Lake Michigan. After two miles of running through downtown Chicago (the tall buildings could cause problems with the GPS signal on your watch), runners go northward for about six miles, then turn back south, running through Boystown, Lincoln Park, and Old Town until they hit the halfway point. There, runners change directions and head east. For miles 14 through 21, runners pass through the West Loop, University Village, Little Italy, and Pilsen. After mile 21, runners turn south for a spin through Chinatown before heading back north toward the finish line in Grant Park.
