Chicago is more than just a big city. It’s a city of neighborhoods and people that represent vibrant and diverse backgrounds and cultures. Every October, runners travel to Chicago to experience this incredible city by running through it at the Bank of America Chicago Marathon. Whether you’re looking for a shakeout run before the Chicago Marathon or want to be part of the excitement of race weekend, we invite you to join us for the Abbott Chicago 5K.

The 2026 Abbott Chicago 5K will take place on Saturday, October 10, 2026.
