Questions about races in Chicago

Does the calendar cover only the city of Chicago?

It includes races in and around Chicago, within 70 km. Each event page names the starting town; check it before planning your trip. Counts reflect the listed races, rather than every race that may exist.

Where can I check registration?

Open the event page and follow the organizer or registration link when available. Check places, price, start time and rules there; a calendar listing does not mean entries are still available.

How do the distance filters work?

5K and 10K show distances close to 5 and 10 km; half and marathon show distances close to 21.1 and 42.2 km. Trail groups mountain races. Races without a published distance appear under All.
