Chicago Marathon – As more than 55,000 runners prepare to race through Chicago, the marathon cements its status as a global powerhouse of tourism, charity, and elite athletic performance.
When the ceremonial cannon misfired into a crowd of spectators during the inaugural 1977 race. wounding the wife and daughter of a founder. few could have predicted the Chicago Marathon would grow into the massive. record-breaking event it is today. On Sunday at 7:20 a.m. the 48th running of the marathon will take over the city. beginning and ending in Grant Park with a field of more than 55. 000 participants—the largest in the event’s history.
For the thousands of athletes navigating the 26.2-mile course. the flat. scenic route through 29 of Chicago’s 77 neighborhoods offers a prime opportunity for personal records and Boston Marathon qualifying times. The logistical ease of the start and finish in Downtown Chicago stands in stark contrast to races requiring hours of pre-dawn transit. drawing runners from all 50 states and over 130 countries. More than 75% of this year’s participants are traveling from outside Illinois. with top international contingents arriving from the United Kingdom. Mexico. Brazil. and Canada.
The race is one of eight prestigious Abbott World Marathon Majors. alongside Tokyo. Boston. London. Cape Town. Sydney. Berlin. and New York City. Its influence extends well beyond the elite field; in 2025. athletes running for the official charity program raised a record $47.1 million for nonprofits. One notable legacy remains Jim Preschlack of Lake Forest. who in 2024 set the event’s all-time fundraising record. collecting $335. 665 for lung cancer research at Northwestern University in honor of his wife. Paula.
Economic data suggests the race is a vital engine for the city. In 2025, the marathon injected nearly $756 million into the local economy, a 7.5% increase over 2024. For local business owners. the influx of visitors—particularly the 20. 000 international runners who tend to stay twice as long and spend twice as much as domestic tourists—serves as a critical post-pandemic boost. While some urban events trigger friction over noise or traffic. the marathon remains a central fixture on the city’s calendar. drawing 1.7 million spectators to the streets.
Competition remains fierce at the front of the pack. Defending champions Jacob Kiplimo of Uganda. who clocked a 2:02:23 last year. and Hawi Feysa of Ethiopia. who hit a personal best of 2:14:56. are both returning. They join a high-caliber professional field that includes Sharon Lokedi, Brigid Kosgei, Amos Kipruto, and American Charles Hicks. The course has seen historic speed in recent years. including Kelvin Kiptum’s 2023 men’s record of 2:00:35 and Ruth Chepngetich’s 2024 women’s record of 2:09:56. Conner Mantz also previously shattered the American record on this pavement with a 2:04:43 finish.
As the city prepares to host its latest record field. the data reveals a steady upward trajectory in participation: from 45. 932 finishers in 2019 to 48. 472 in 2023. and 55. 744 last year. With over 200,000 people applying to join the 2026 race, the marathon’s demand continues to outpace its capacity. Whether for the elite runners chasing world records or the one-third of participants currently fundraising for a cause. the event remains a complex intersection of individual endurance. charitable impact. and the city’s broader economic health.
