Racing in Illinois
Illinois runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in November, December, and May, with races most often held in Chicago, Springfield, Belleville, and Rockford.
Races in Illinois are mostly flat prairie and farmland across the central and southern parts of the state, with the Lake Michigan shoreline and skyline backdrop shaping courses around Chicago. Expect fast, flat road races statewide and scenic lakefront routes in and around the city.
Conditions vary widely by region across Illinois, so weather lives where it’s accurate — each race page shows its typical race-day high, low, and rain chance from NOAA climate normals for that venue and date.
