Chicago 13.1

Lace up for an unforgettable journey through Chicago's vibrant West Side at the Chicago 13.1, set to take place on June 7, 2026. This popular half marathon offers a unique perspective of the Windy City, venturing beyond the typical lakefront routes to showcase diverse and culturally rich neighborhoods. Runners can anticipate typical race day conditions with highs around 79F and lows around 60F, with a 17% chance of precipitation, making for potentially warm but generally favorable running weather.

The Bank of America Chicago 13.1 course, starting and finishing in Garfield Park, provides a captivating tour through historic parks and boulevards, including scenic loops through Humboldt and Douglas Parks. While some sections outside the parks feature long, straightaways with less shade, the overall flat terrain makes it a fast and accessible race for many. Runners consistently praise the abundant aid stations, provided by hydration sponsor Nuun, which are stocked with water and even wet sponges, ensuring ample support throughout the 13.1 miles.

Known for its exceptional organization by the same team behind the Chicago Marathon, the Chicago 13.1 has quickly built a reputation as a world-class event, growing significantly since its inaugural run in 2022. Participants rave about the smooth logistics, robust cheer stations from local running clubs, and the lively Race Day Festival held at Garfield Park, which offers entertainment, health activities, and community engagement. This race is not just a run; it's an immersive experience that celebrates the spirit and diversity of Chicago's West Side.
