Ever wondered what it feels like to run through one of America’s most iconic cities with thousands of cheering fans lining the streets? The Chicago Marathon 2026 is shaping up to be one of the most exciting races yet, and whether you’re a runner, a spectator, or just a fan of big cultural moments, there’s plenty to look forward to. Let’s dive into what makes this marathon so special and why it’s worth marking October 11, 2026, on your calendar.
When and Where It’s Happening
The Bank of America Chicago Marathon traditionally takes place on the second Sunday of October, and in 2026, that date is October 11. The race begins in Grant Park, right in the heart of downtown Chicago, and winds through 29 neighborhoods before looping back to the finish line in the same park.
This course is famous for being flat and fast, which makes it a favorite for runners chasing personal records—or even world records.
Why the Chicago Marathon Stands Out
Chicago isn’t just another marathon city. It’s part of the World Marathon Majors, alongside Boston, New York, London, Berlin, and Tokyo. That means it attracts elite athletes from around the globe, as well as everyday runners who want to experience the thrill of a world-class race.
Here are a few standout facts:
The first Chicago Marathon took place in 1977, with just over 4,000 participants.
Today, the race welcomes over 45,000 runners from more than 100 countries.
The course record for men is 2:03:45, set by Dennis Kimetto in 2013.
For women, Brigid Kosgei stunned the world in 2019 with a 2:14:04, breaking the women’s marathon world record at the time.
How to Get In
Registration for the Chicago Marathon 2026 opens months in advance, and there are several ways to secure a spot:
Lottery System – Most runners enter through a random drawing.
Time Qualifiers – If you’ve run a marathon fast enough to meet the qualifying standards, you can bypass the lottery.
Charity Entries – Many runners join through fundraising for nonprofit organizations.
Legacy Runners – Those who’ve completed multiple Chicago Marathons may qualify for guaranteed entry.
Did You Know?
Chicago’s marathon course is so flat that it’s often used by runners hoping to qualify for the Boston Marathon, which requires strict qualifying times.
What Makes Race Day Special
The Chicago Marathon isn’t just about running—it’s about the city itself. Along the route, runners pass through neighborhoods like Pilsen, Chinatown, and Lincoln Park, each offering its own flavor of music, food, and cheering crowds.
Spectators are a huge part of the experience. In fact, more than 1.7 million people line the streets to cheer on runners every year. That energy is part of what makes Chicago unforgettable.

I’ve never run the Chicago Marathon myself, but I’ve stood along the sidelines, coffee in hand, cheering as strangers pushed themselves past mile 20. There’s something deeply moving about watching thousands of people chase a goal together. It’s not just about running—it’s about resilience, community, and the joy of being part of something bigger than yourself.
